Figure 2 HP ProLiant BL p-Class GbE2 Interconnect Switch and QuadSX Interconnect Module Features The ProLiant BL p-Class GbE2 Interconnect Switch and interconnect modules are designed for easy installation and high performance in an environment where traffic on the network and the number of users increases continually.
• Remote Monitoring (RMON) feature, which allows network devices to exchange network monitoring data. RMON performs the following major functions: • Gathers cumulative statistics for Ethernet interfaces • Tracks a history of statistics for Ethernet interfaces • Creates and triggers alarms for user-defined events • Quality of Service (QoS) feature, where the switch uses the Differentiated Services (RFCs 2474 and 2475) architecture to provide QoS functions.
GbE2 Interconnect Switch redundancy The ProLiant BL p-Class GbE2 Interconnect Switch offers several redundancy and failover features. With these features, the network configuration can be designed to allow for continued network access to each server blade in case of a component or link failure.
• Statistic monitoring including port utilization, data packets received/transmitted, port error packets, trunk utilization, and so on • Ping and trace route capability • Remote syslog with support for primary and secondary syslog server • Portable Diagnostic Station option to configure and diagnose a GbE2 Interconnect Switch and server blade removed from the rack • The ability to return the GbE2 Interconnect Switch to known good condition in case of firmware corruption • State information dump f
GbE2 Interconnect Switch architecture The ProLiant BL p-Class system provides integrated switching technology for network cable reduction. The following diagram illustrates the Ethernet signal connectivity between server bays and the interconnect bays through the backplane for the p-Class server enclosure.
The following diagram illustrates the Ethernet signal connectivity between server bays and the interconnect bays through the backplane for p-Class server enclosures with enhanced backplane components that support high-density blade servers. Figure 4 Ethernet signal connectivity for server enclosures with enhanced backplane components The interconnect switch does not affect or determine NIC enumeration and the associated mapping of NIC interfaces to interconnect switch ports.
HP Ethernet Connectivity Mapper utility (hpecm) The HP Ethernet Connectivity Mapper is a utility used to determine the NIC name enumeration and the associated mapping to switch ports. The physical connections between server blade network interface controllers (NICs) and switch ports depend on the server blade type and the enclosure backplane type, as described above. The logical NIC name enumeration depends on the operating system software (such as Local Area Connection, Local Area Connection 2, etc.
Layer 2 switching technology allows the GbE2 Interconnect Switch to look into data packets and redirect them based on the destination MAC address. This reduces traffic congestion on the network because packets, instead of being transmitted to all ports, are transmitted to the destination port only. IEEE 802.1Q-based Virtual Local Area Network The ProLiant BL p-Class GbE2 Interconnect Switch provides support for a total of 255 IEEE 802.
Interconnect Switch can also be uploaded to a TFTP server, a configuration file can be downloaded into a GbE2 Interconnect Switch from a TFTP server, and configuration settings can be saved to the TFTP server. Store and forward switching scheme The GbE2 Interconnect Switch provides a store and forward switching scheme that allows each packet to be buffered (stored) before it is forwarded to its destination. While this method creates latency, it improves reliability in a heavily used interconnect switch.
authenticated using a shared key that is not sent over the network. In addition, the remote administrator passwords are sent encrypted between the TACACS+ client (the switch) and the back-end TACACS+ server. The GbE2 Interconnect Switch supports: • Only standard ASCII inbound login authentication. PAP, CHAP, or ARAP login methods are not supported. Onetime password authentication is also not supported. • Authorization privilege levels of only 0, 3, and 6.
Redundant images in firmware The GbE2 Interconnect Switch can store up to two different software images, called image1 and image2, as well as boot software, called boot. When you download new software, you are given the ability to specify where it is to be placed: either into image1, image2, or boot. For example, if your active image is currently loaded into image1, you should probably load the new image software into image2.

The following are the enterprise SNMP traps supported in the GbE2 Interconnect Switch: Table 14 Supported enterprise SNMP traps Trap name Description bt2SwDefGwUp Signifies that the default gateway is alive. bt2SwDefGwDown Signifies that the default gateway is down. bt2SwDefGwInService Signifies that the default gateway is up and in service. bt2SwDefGwNotInService Signifies that the default gateway is alive but not in service.
Safe Mode configuration Introduction GbE2 Interconnect Switch configuration files are specified in text format. Trivial File Transfer Protocol (TFTP) or Secure Copy (SCP) services can to be used to upload and download these text-based configuration files. When these configuration files are downloaded and applied to the GbE2 Interconnect Switch, the GbE2 Interconnect Switch interprets the contents and applies it to the system as active configuration.
GbE2 Interconnect Switch replacement scenario using a Safe Mode configuration When an in-production GbE2 Interconnect Switch fails: 1. Remove the failed GbE2 Interconnect Switch. 2. Insert the spare GbE2 Interconnect Switch that was previously configured for safe operation. 3. Upgrade to new firmware if appropriate. 4. Download the correct configuration for that particular GbE2 Interconnect Switch.
Method 2: Via any switch management interface using TFTP functionality 1. Power up the switch using the Diagnostic Station or by inserting the switch in a non-production blade enclosure. After resetting the switch to factory settings (if required), login to the switch CLI via the serial console as Admin. 2. If the switch cannot get BootP assigned IP settings, configure the switch IP address settings so that it can access a TFTP server on the attached network. 3.
Electrostatic discharge Overview To prevent damage to the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage, observe the following precautions: • Avoid hand contact by transporting and storing products in static-safe containers.
RJ-45 pin specification When connecting the HP ProLiant BL p-class GbE2 Interconnect Switch to a switch, bridge, or hub, an Ethernet cable is necessary. The following figure displays the standard RJ-45 receptacle/connector for 10/100 Mb/s and Gigabit over Copper ports. Table 15 indicates the pin number and wire color assignments for the switch-to-network adapter card connection, and the Ethernet cable for the switch-to-switch, switch-to-hub, or switch-to-bridge connection.
Troubleshooting This section provides information on solutions to problems that may occur during the configuration and operation of a ProLiant BL p-Class GbE2 Interconnect Switch. The following tables provide steps to take before calling your service representative. Following are four tables with basic troubleshooting information: • Setting up and accessing—Table 17 contains general troubleshooting information about setting up and accessing the GbE2 Interconnect Switch.
Table 17 Troubleshooting: Setting up and accessing Problem Possible cause Possible solution The RJ-45 connector on the switch or LED • is faulty. • After checking and replacing the cable, if no link LED displays, check whether the port is transferring data. If yes, the LED is faulty. If no, it could be a faulty RJ-45 connector. Call your service representative. This could be caused by using a crossover cable instead of a straight-through cable.
Table 17 Troubleshooting: Setting up and accessing Problem Possible cause Possible solution Password is not accepted by the GbE2 Interconnect Switch using the remote console interface immediately after a reboot. The GbE2 Interconnect Switch is still working on network convergence. Wait up to 10 seconds, and the password should be accepted. Cannot connect to the GbE2 Interconnect Switch console interface remotely using SSH. The GbE2 Interconnect Switch IP address • may not be configured or correct.
Table 18 Troubleshooting: Configuring Problem Possible cause Possible solution After connecting more than one port to another switch or destination device, the port activity LEDs continuously indicate activity. Because there are multiple links across this device and the destination device, they form loops, which cause broadcast storms. Enable STP if you want multiple links. This setting prevents loops and maintains standby links for resilience in case of primary link failure.
Table 19 Troubleshooting: Using a TFTP server Problem Possible cause While using TFTP to download firmware, The TFTP server is not available to the GbE2 Interconnect Switch fails to connect to or there is connectivity failure connect to the TFTP server, or after between the switch and TFTP server. connection the download fails. The firmware file is not found on the TFTP server. The file name could be wrong.
Table 20 Troubleshooting: Upgrading firmware using the serial port Problem Possible cause Possible solution After forcing the GbE2 Interconnect Switch into the download mode, the console screen displays a message to change the baud rate for your terminal emulation session for XModem transfer and does not display CCCC…. Your terminal emulation session baud rate does not match the GbE2 Interconnect Switch serial console baud rate in the download mode.
