Chapter Installing and Configuring the SilkWorm 4100 2 This chapter provides the following information: • • • • • • “Installation and Safety Considerations,” next “Items Included with the SilkWorm 4100” on page 2-2 “Setting Up the SilkWorm 4100 as a Standalone Unit” on page 2-3 “Installing the SilkWorm 4100 in an EIA Cabinet” on page 2-3 “Configuring the SilkWorm 4100” on page 2-3 “Recommendations for Cable Management” on page 2-10 Installation and Safety Considerations You can install the SilkWorm 41
2 Items Included with the SilkWorm 4100 If installing the switch in a cabinet: • • The cabinet must be a standard EIA cabinet. • Ground all equipment in the cabinet through a reliable branch circuit connection and maintain ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power strip. • Ensure that airflow and temperature requirements are met on an ongoing basis, particularly if the switch is installed in a closed or multirack assembly.
Setting Up the SilkWorm 4100 as a Standalone Unit 2 Setting Up the SilkWorm 4100 as a Standalone Unit The SilkWorm 4100 can be configured as a standalone unit, which means that it resides outside of a rack. To configure the SilkWorm 4100 as a standalone unit: 1. Unpack the SilkWorm 4100 and verify that all ordered items are present. 2. Clean the four corner depressions on the bottom of the switch and place a rubber foot in each one.
2 Configuring the SilkWorm 4100 3. “Connecting to the Switch Using the Serial Connection” on page 2-5 4. “Setting the Switch IP Address” on page 2-5 5. “Creating an Ethernet Connection” on page 2-6 6. “Completing Switch Configuration” on page 2-6 Caution Do not connect the switch to the network until the IP address is correctly set. For instructions on how to set the IP address, see “Configuring the SilkWorm 4100” on page 2-3.
Configuring the SilkWorm 4100 Flow control: • 2 None In a UNIX environment, enter the following string at the prompt: tip /dev/ttyyb -9600 Connecting to the Switch Using the Serial Connection To log in to the switch through the serial connection: 1. Verify that the switch has completed POST. When POST is complete, the port status and switch power and status LEDs return to a standard healthy state; for information about LED signals, refer to “Interpreting LED Activity” on page 3-1. 2.
2 Configuring the SilkWorm 4100 Creating an Ethernet Connection To create an Ethernet connection to the SilkWorm 4100: 1. Remove the plug from the Ethernet port. 2. Connect an Ethernet cable to the switch Ethernet port and to the workstation or to an Ethernet network containing the workstation. Note At this point, the switch can be accessed remotely, by command line or by Brocade Advanced Web Tools. Ensure that the switch is not being modified from any other connections during the remaining tasks.
Configuring the SilkWorm 4100 2 a. Remove the plugs from the ports to be used. b. Position a transceiver so that it is oriented correctly and insert it into a port until it is firmly seated and the latching mechanism clicks. For instructions specific to the type of transceiver, refer to the transceiver manufacturer’s documentation. Note The transceivers are keyed to ensure correct orientation. If a transceiver does not install easily, ensure that it is correctly oriented. c. 5.
2 Configuring the SilkWorm 4100 Brocade recommends backing up the configuration on a regular basis to ensure that a complete configuration is available for downloading to a replacement switch. For specific instructions about how to back up the configuration, refer to the Fabric OS Procedures Guide. The switchShow, fabricShow, and configUpload commands are described in detail in the Fabric OS Command Reference Manual.
Configuring the SilkWorm 4100 1. Log in as admin. 2. Enter the tsClockServer [ipaddr] command 2 The ipaddr variable represents the IP address of the NTP server that the switch can access. This argument is optional; by default, its value is “LOCL”. Example switch:admin> tsclockserver LOCL switch:admin> tsclockserver 132.163.135.

3 Interpreting POST Results Interpreting POST Results POST is a system check that is performed each time the switch is powered on, rebooted, or reset, and during which the LEDs flash different colors. To determine whether POST completed successfully and whether any errors were detected: • • Verify that the LEDs on the switch indicate that all components are healthy (LED patterns are described in Table 3-1 on page 3-3 and Table 3-2 on page 3-5). If one or more LEDs do not display a healthy state: 1.
Maintaining the SilkWorm 4100 3 Diagnostic Tests In addition to POST, Fabric OS includes diagnostic tests to help you troubleshoot the hardware and firmware. This includes tests of internal connections and circuitry, fixed media, and the transceivers and cables in use. The tests are implemented by command, either through a telnet session or through a terminal set up for a serial connection to the switch.
3 Maintaining the SilkWorm 4100 Fan Assemblies The three fan assemblies are hot-swappable if replaced one at a time. They are identical and fit into any fan assembly slot. Each fan assembly contains two fans, identified by Fabric OS as follows (viewing the switch from the nonport side): • • • Fan assembly #1 is on the right. Fan assembly #2 is in the center.

A port is defined as a U_Port when it is not connected or has not yet assumed a specific function in the fabric. User Datagram Protocol. A protocol that runs on top of IP and provides port multiplexing for upperlevel protocols. Underwriter's Laboratories. A product-safety testing and certification organization; independent, notfor-profit. Upper-level protocol.
X X.25 xlate domain A protocol that uses logical channels. X.25 allows high-quality communications between computers and can accommodate “noisy” data communications through error-detection and -correction (retransmission) algorithms. Translate domain. A router virtual domain that represents an entire fabric. Device connectivity can be achieved from one fabric to another, over the router and through this virtual domain, without merging the two fabrics. Also known as “phantom domains.
