You can also see the SBM’s serial number on the back left corner of the module’s physical hardware. Default hostname: ______________________________ You will also need to know the SBM’s permanent hostname, which is the name in the SBM’s domain computer account and the domain name.
Introduction Ensure that You are Ready to Complete the Setup Wizard Either: • A .pfx certificate/private key file Certificate filename: _______________________ Private key password: ______________________ Caution Whoever generates the .pfx file must mark the key as exportable. Otherwise, the Media Gateway cannot start and the installation will fail.
Introduction Ensure that You are Ready to Complete the Setup Wizard This is the listening port that the CS Administrator defined for the PSTN gateway when adding the SBM as a survivable branch appliance. Figure 11 shows the default ports for TCP and TLS marked with 1. Figure 1-1. SIP Ports SIP transport protocol for communications from the Media Gateway to the Mediation Server: • TLS (recommended) • TCP This is the protocol defined for the SBM’s Mediation Server in the topology.
Introduction Ensure that You are Ready to Complete the Setup Wizard Table 1-1.
Introduction Ensure that You are Ready to Complete the Setup Wizard Routing rules and normalization have been established for the SBM’s pool. A CS Health Monitoring Configuration has been created for the SBM’s pool (so a Lync test call can be placed without specifying user information). Media Bypass has been enabled for the SBM (optional but recommended) You are now ready to run the Setup Wizard. Important You must complete all initial setup tasks through the Setup Wizard.
2 Complete the Setup Wizard Access the Setup Wizard You should be at the Welcome page of the SBM Setup Wizard. To access the wizard, open a Web browser and navigate to the SBM’s IP address. Supported Web browsers include: Windows Internet Explorer (IE) 7 Windows IE 8 Mozilla Firefox 3.6 Note You must complete all initial setup tasks through the Setup Wizard.
Complete the Setup Wizard Using the Setup Wizard Using the Setup Wizard The figure below displays the Welcome page, which is the first page in the Setup Wizard. Figure 2-1.
Complete the Setup Wizard Using the Setup Wizard General Troubleshooting Tips Keep these tips in mind for a smoother experience in setting up your SBM. Access the SBM via Remote Desktop Protocol (RDP) You must set up the SBM using the Setup Wizard because the wizard completes some setup in the background. However, you can access the SBM via RDP during the process if you want.
Complete the Setup Wizard Using the Setup Wizard You might see the location for a log file. You can then access the SBM via RDP, navigate to the log file’s location, and read the log for detailed messages. You can also insert a USB storage device in the SBM’s USB slot (make sure to use the slot on the SBM’s front panel and not the USB slot on the HP zl switch chassis). Then you can copy the log file to the USB storage device and send the file to an expert for help. Cmdlet Log file location Figure 2-2.
Complete the Setup Wizard Using the Setup Wizard Figure 2-3. Setup Wizard > Installation Process Overview Page 3. Click Next.
Complete the Setup Wizard Configure IP Settings Configure IP Settings Your SBM might already have the correct IP settings either assigned to it by the domain DHCP server or set during the initial installation. The SBM requires: A valid IP address and default gateway address, which provide the SBM with connectivity to the data center The domain DNS server IP address The IP settings should typically be configured on the internal Ethernet interface 2.
Complete the Setup Wizard Configure IP Settings Management Interface—The 1 Gigabit Management port on the front of the SBM, which you can connect directly to a management station. This interface is intended to provide backup management access to the SBM, typically for support purposes. You configure the settings for each interface by clicking the corresponding tab. You can set the basic settings manually, or the SBM can receive them using DHCP.
Complete the Setup Wizard Configure IP Settings Figure 2-4. Setup Wizard—Configure IP Settings Page If you need help configuring a field, click the help icon (?) in the Setup Wizard. Before you click Next, you must manually commit the changes made in each tab by clicking the Apply button at the bottom of the tab. (Before you commit changes, you can revert the settings to those that were last applied by clicking Discard Changes.
Complete the Setup Wizard Configure IP Settings Note When you configure an SBM Ethernet interface in the Setup Wizard, the interface must either receive all settings using DHCP or be configured with all settings manually. However, these interfaces do support receiving a DHCP IP address and default gateway but using a manually-defined DNS server address. If your environment requires such a setup, you must access the SBM via RDP and configure the Ethernet interfaces using the typical Windows procedure.
Complete the Setup Wizard Configure the System Time Configure the System Time This page displays the SBM time. On this page, you can also set the SBM’s timezone and Daylight Saving Time settings. The SBM takes its date and time from the HP zl switch chassis in which it is installed. Because the domain join and other functions will fail unless the SBM time matches the domain controller's, the HP zl switch should be synchronized to the same time as the domain controller. Figure 2-6.
Complete the Setup Wizard Configure the System Time Although you cannot configure the time on the SBM, you can configure these settings: Timezone Caution Remember to click Set Time Zone after you select the correct zone from the list. Whether Daylight Saving Time is enabled If you set Daylight Saving Time on the SBM but not on the switch, the SBM will become unreliable until this setting is reconciled. If you experience this problem, first reconcile the setting on the HP zl switch and the SBM.
Complete the Setup Wizard Configure the System Time 3. Set the SNTP mode: hostzlswitch(config)# sntp unicast 4. Configure the SNTP server IP address (either the domain controller or an SNTP server with the correct time): Syntax: sntp server priority 1 Replace with the reachable IP address of the domain controller or SNTP server. 5. Set the timezone: Syntax: time timezone <-780 - 840> The switch calculates the time zone offset in minutes. For example, type 60 for GMT +1. 6.
Complete the Setup Wizard Configure the System Time Set the HP zl Switch Time Manually Follow these steps: 1. Open a CLI management session with the HP zl switch and access the global configuration context: hostzlswitch# config 2. Set the date: Syntax: clock set Replace with the two-digit date, two-digit month number, and four-digit year. For example, 05:05:2010 3.
Complete the Setup Wizard Join the SBM to the Domain Join the SBM to the Domain On this page, you join the SBM to the domain. 1. For Computer Name, type the SBM’s permanent name. It is very important that you enter the correct name in order for the SBM to work with the other servers in the Lync Server topology. Note that the computer name is only the hostname portion of the SBM’s FQDN. For example, if the SBM’s designated FQDN is HP-SBM.example.hp.com, type HP-SBM. 2.
Complete the Setup Wizard Join the SBM to the Domain 4. Click Join. 5. When the domain join is successful, the SBM reboots and a countdown is displayed on the window, indicating the time until the SBM will have completed the reboot. Figure 2-8. Setup Wizard—Reboot Countdown 6. Note If you have launched the Setup Wizard from the Remote Desktop, you will lose access. Wait until the SBM reboots (if you have physical access to it, verify that the Module Status LED glows solid green).
Complete the Setup Wizard Join the SBM to the Domain 8. When prompted to log in, do not log in as the local Administrator. Instead, type the credentials of a domain user with sufficient privileges to finish configuring the SBM (typically, the credentials that you used to join the SBM to the domain). Remember to include the domain name in your username, either: • \ • @ Figure 2-9.
Complete the Setup Wizard Join the SBM to the Domain Troubleshooting The sections below give troubleshooting tips for the section above: “Failed Domain Join” on page 2-19 “When you have succeeded in joining the domain, return to step 5 on page 2-17.
Complete the Setup Wizard Join the SBM to the Domain Failed Login Contact your Domain Administrator and verify you are a member of RTCUniversalSBATechnicians. If not, ask the administrator to add you to this group. If you are a member of the group, you might have one of these two problems: The SBM’s clock does not match the domain controller’s clock.

Complete the Setup Wizard Initiate the Installation Process SBM Service Principle Hame (SPN) Prerequisite. This prerequisite fails if the Domain or Enterprise Administrator has not configured this setting. Without the proper SPN, the SBM does not receive the proper group memberships when it is added to the Lync topology. As far as you are concerned, you will not be able to complete the setup, and the SBM will not be able to provide the communication services. To resolve this issue: 1.
Complete the Setup Wizard Initiate the Installation Process Next, the CS Administrator must check the topology and verify that the SBM has been added as a survivable branch server with the correct FQDN. (See Appendix A: “Ready the Data Center for an SBM Deployment” or Microsoft documentation for more details.) If any changes were made to the topology, the CS Administrator must publish it. (The topology is automatically enabled when published.
Complete the Setup Wizard Initiate the Installation Process SBM Not Added to the Topology.
Complete the Setup Wizard Initiate the Installation Process Failed Network Connection. If you see a “network related or instancespecific” error, the SBM’s link to the server at the data center that stores the topology might have failed. Test this theory by pinging that server from a command prompt via RDP or from the SBM OS CLI. If the link has failed, you can either: Wait until the link is restored and then click Restart Automated Replication Process.
Complete the Setup Wizard Initiate the Installation Process Figure 2-18. Setup Wizard—Perform Lync Server Replication Failed > Next Steps Continued If the topology imports successfully, you can move on with the wizard. However, you will need to regain access to the data center before you start the Lync Server services and finish the wizard.
Complete the Setup Wizard Install Server Certificates Install Server Certificates Before you install the certificate, you need to determine whether the SBM has the correct CA certificate chain installed. Many domains use group policy objects (GPOs) to automatically push this chain to devices when they join the domain. Therefore, the SBM might have received the chain already; ask your data center contact.
Complete the Setup Wizard Install Server Certificates Figure 2-20. Setup Wizard—Install Server Certificates > Import Certificate Chain 6. You might be prompted to log back in to the Setup Wizard after the certificate is updated. Do so. Then move on to the section below. Select the Option for Installing the Certificate Once you know that the CA certificate chain is installed, you can install the SBM’s Lync Server certificate.
Complete the Setup Wizard Install Server Certificates 1. In the Install Lync Server Certificates page, select Automatically Request Certificate from Microsoft Certificate Authority. Figure 2-21.

Complete the Setup Wizard PSTN Configuration PSTN Configuration You have now successfully completed the initial Lync server setup. As a survivable branch solution, the SBM includes other components. In this page, you configure the built-in Media Gateway and establish a connection to your PSTN carrier. Do not move on until you have completed the PSTN Setup Wizard and have checked the Media Gateway status and channel status to verify that the PSTN connection is up.
Complete the Setup Wizard PSTN Configuration Important Typically, the SBM routes PSTN calls through ports on its telephony cards to a PSTN carrier. You must set up the Media gateway to manage the PSTN connections. However, when the SBM uses SIP trunking, PSTN calls bypass the SBM’s Media Gateway; instead the SBM routes the PSTN calls through its internal port 2 toward a WAN router that connects to an Internet telephony service provides (ITSP).

4 Support Remote Monitoring Supported Solutions Many organizations have centralized solutions for monitoring and managing network assets such as the HP Survivable Branch Communication zl Module (SBM) powered by Microsoft LyncTM. You can monitor the SBM remotely using one or more of these supported remote monitoring tools: ■ OpenView Agent ■ SNMP server ■ Syslog server ■ Microsoft Operations Monitor Agent You should refer to the documentation for your tool.
Support Remote Monitoring SNMP MIBs Ensuring Support You do not need to complete any extra configuration on the SBM to enable it to work with the supported monitoring solutions. However, if your solution relies on SNMP, the SNMP server requires the proper MIBs (see “SNMP MIBs” on page 4-3). In addition, someone must verify that any firewalls between the SBM and the remote solution permit the appropriate traffic. Finally, the SBM has also had its security hardened in a number of ways.
Support Remote Monitoring SNMP MIBs Media Gateway MIBs The SBM also has MIBs for its Media Gateway, which are stored in the SBM’s hard drive in the C:\Program Files\Hewlett-Packard\SIP-PSTN Gateway\config\mibs directory. (You can access this directory using RDP.) These MIB files have a .txt extension. The Media Gateway uses these MIBs: ■ SANGOMA-IF-MIB ■ GW-CALL-STATS-MIB ■ SANGOMA-IF-DECLARATION-MIB The other files that you see are necessary for those MIBs to function.
5 Manage Updates Install Updates To update the software of the HP Survivable Branch Communication zl Module (SBM) powered by Microsoft LyncTM, you will receive an installer file, which you run in a Remote Desktop Protocol (RDP) session with the SBM. The SBM’s configurations (including the Media Gateway settings) will be preserved after the update. However, the HP SBM must reboot after the installation. Therefore you should schedule a network outage during the update procedure.
Manage Updates Patches and Hotfixes Alternatively, you can place the file in a shared network folder to which the SBM has access. 4. Copy the update installer to the SBM’s desktop. You must run this as an administrator. If you do not, you will be prompted to enter administrator credentials. 5. When the installation is complete, you will be prompted to restart the SBM. Click Yes.
Manage Updates Driver Updates Driver Updates If you need to update the drivers for your PSTN telephony boards, refer to the Sangoma website (wiki.sangoma.com/wanpipe-windows-drivers). You can download both the drivers and instructions for installing them from there. Before you update the drivers, you must shut down the Media Gateway. Access the SBM Dashboard (contact the SBM at its FQDN) and click Stop next to HP Media Gateway.
6 Troubleshooting Overview This chapter teaches you how to perform basic PSTN troubleshooting, how to put T1/E1 lines into loopback, and how to view the status and statistics for PSTN connections. Several sections at the end of the chapter provide information on fixing specific problems. Basic Digital Line Troubleshooting This section guides you through basic troubleshooting of your PSTN connections: 1. Find your line’s interface ID. 2. View alarms on the line. 3. Place a line in loopback mode.
Troubleshooting Basic Digital Line Troubleshooting Figure 6-1. Remote Desktop—Open a Command Prompt as an Administrator 2. Enter wanrouter interfaces. Figure 6-2.
Troubleshooting Basic Digital Line Troubleshooting 3. The Interface Name column lists the interface ID for each of active interface. Depending on the type of signaling for your E1/T1/J1 line, you might see multiple interface IDs; one for the voice data channels and others for the data control channels (the D-channels). If you have found your ID, move to “View the Alarms on the Line” on page 6-7.
Troubleshooting Basic Digital Line Troubleshooting 5. Click the Groups of channels tab and note the interface ID, which is listed as the Interface Name. Figure 6-4.
Troubleshooting Basic Digital Line Troubleshooting View the Alarms on the Line To view the alarms on a line, follow these steps: 1. Access the SBM via Remote Desktop Protocol (RDP). (See “Remote Desktop Protocol (RDP)” on page 3-20 of Chapter 3: “Manage and Monitor the HP SBM Locally.”) 2. Open a command prompt by right-clicking and selecting Run as administrator. Figure 6-5. Remote Desktop—Open a Command Prompt as an Administrator 3.
Troubleshooting Basic Digital Line Troubleshooting Table 6-1. Possible Reasons for E1/T1/J1 Alarms Alarm Definition Possible Problems OOF Out of Frame The line coding or the framing format does not match the PSTN carrier’s settings. LOF Loss of Framing The line is experiencing a clocking problem. Generally, the interface should take the clock from the line (default setting). LOS Loss of Signal (continuity problem) • The cable is disconnected or bad.
Troubleshooting Implement a Loopback Implement a Loopback When your PSTN connection has an LOS alarm, but you cannot determine the error, you might put the line into a local loopback to determine the problem. In addition, your PSTN carrier might ask you to put the circuit in a loopback mode for testing. There are two general types of loopback: Local—The SBM sends data to the CO, which loops it back to the SBM. In this case, you are responsible for initiating the BERT and analyzing the results.
Troubleshooting Implement a Loopback Connect the Port to be Tested You have three options for connecting the port that you plan to put into local loopback: Leave the port connected to the Telco. Table 6-2. Pin Signal 1 RRING 2 RTIP 4 TRING 5 TTIP Connect the port to a loopback connector. Use an RJ-45 cable in which you have tied the pins together as shown in the table below. Table 6-3.
Troubleshooting Implement a Loopback Enable Master Clocking If you connected the port to a loopback connector or to another E1/T1/J1 port, the port that you are testing must act as the master clock. If you are connecting the port to the Telco, talk to your carrier and ask whether your port should be the master clock. Follow these steps to enable master clocking: 1. Open the Driver properties window: a. Open the Device Manager from the Control Panel. b. Expand Sangoma Communication Devices. Figure 6-6.
Troubleshooting Implement a Loopback Display Interface Driver Events It is a best practice to open a command line window for monitoring activity on the tested interface. 1. Open a command prompt, running the command as an administrator. 2. Enter this command: stail.exe Leave this window open throughout the rest of the process. Put the Line into Loopback Complete each task to put the line into loopback. Open a Command Line. Open a different command prompt (again selecting Run as administrator).

C Command-Line Reference Overview This chapter describes the commands provided by the command line interface (CLI) for the HP Survivable Branch Communication zl Module (SBM) powered by Microsoft LyncTM. This CLI is intended for basic monitoring and initial IP configuration. Most management and configuration should be performed using the Setup Wizard, Dashboard, and Remote Desktop as described in previous chapters of the guide.
Command-Line Reference Overview Table C-1.
Command-Line Reference Overview All italics indicate variables for which you must supply a value when executing the command. Some commands also include keywords, which are indicated in the command type. For example, name is a keyword for the services command. CLI Help Like the CLI for HP switches, the SBM CLI provides help that displays command syntax, including explanations of commands and command options.
Command-Line Reference Operator Context Commands Displaying Help for a Command You can display a list of help summaries for a particular command by typing: hostzlswitch(hp-sbm-branch-)# help Operator Context Commands The Operator context features a limited number of commands that allow you to see information about the SBM. To access the Operator context, access the operator context of the CLI of the HP zl switch in which the SBM is installed.
Command-Line Reference Operator Context Commands If other types of ONE Services zl Modules are also installed in the switch, the host switch assigns the SBM and each ONE Services zl product a different index number, based on the order in which each one boots. For example, if you install the SBM and boot it first, the host HP zl switch assigns it the index number 2.
Command-Line Reference Operator Context Commands For example, if you want to enter the Manager EXEC context for the SBM’s ONE App OS, enter one of the following commands: hostzlswitch> services c 3 hostzlswitch> services c name hp-sbm-branch To verify your location in the CLI, check the prompt. It is hostzlswitch(hp-sbm-branch)>. The following sections describe commands that are available from the Operator context of the SBM’s ONE-App OS. exit The exit command moves you back one context level.
