  • Page 56: Configure Ip Addresses For Cp Cards

    Configure IP addresses for CP cards The Core Switch 2/64 and the SAN Director 2/128 Director each require three IP addresses, which are configured using the ipAddrSet command. IP addresses are required for both CP cards (CP0 and CP1) and for the switch. NOTE: Use a block of three IP addresses that are consecutively numbered in the last octet.

  • Page 57: Configure Ip Address For The Switch

    NOTE: The host name is the name assigned to the CP card. The same gateway address must be used for both CP cards (these gateway addresses are referenced for the IP addresses). Press Enter to update the IP address of the active CP card immediately. Repeat these steps to configure the IP address of the standby CP card.

  • Page 58: Establish An Ethernet Connection

    Reboot the CP card by entering the reboot command at the prompt. CAUTION: The terminal serial port can be used to monitor error messages through a serial connection. HP does not recommend using the terminal serial port as a command interface during normal operations.

    Set the Domain ID Each switch in the fabric must have a unique Domain ID. You can set the Domain ID using the configure command. You can also allow the system to set the Domain ID automatically. NOTE: The default Domain ID for the Core Switch 2/64 SAN Director 2/128 is 1.

  • Page 61: Enable Software Licenses

    Position one of the SFP transceivers so that the key is oriented correctly to the port. Insert the transceiver into the port until it is firmly seated and the latching mechanism clicks. Transceivers are keyed so that they can be inserted only with the correct orientation. If a transceiver does not slide in easily, ensure that it is correctly oriented.

  • Page 62: Back Up The Configuration

    Back up the configuration HP recommends that you save all key configuration data for the Core Switch 2/64 or the SAN Director 2/128—including license key information—and upload it to a host for emergency reference.

    Obtaining chassis and component status The CLI commands listed in Table 14 provide status and environmental information about the chassis and its components. These commands provide information only, and they do not interrupt traffic flow. For more information about these commands, refer to the HP StorageWorks command reference guide for the Fabric OS version running on your switch.

  • Page 80: Interpreting Post And Boot Results, Post

    Interpreting POST and boot results The Core Switch 2/64 and the SAN Director 2/128 perform power on self test (POST) by default each time the chassis is powered on or the switch is rebooted or reset. You can reboot the switch using the switchReboot, reboot, or fastBoot commands. The fastBoot command reboots the switches without running POST.

  • Page 81: Boot, Diagnostics

    Boot Boot completes in a minimum of three minutes if POST is run. In addition to POST, boot includes the following steps after POST is complete: • Universal port configuration is performed. • Links are initialized. • Fabric is analyzed. If any ports are connected to other switches, the switch participates in a fabric configuration.

  • Page 90: Replacing The Cable Guides (pillars), Replacing A 16-port Card And Filler Panel, Preliminary Steps

    Replacing the cable guides (pillars) You can use cable guides (pillars) to organize the port cables into logical groups, such as port quads (sets of four neighboring ports). The cable pillars do not attach to the chassis. The cable pillars also serve to keep the cables evenly spaced and hold them away from the 16-port card to prevent them from bending to less than the minimum bend radius.
