Reconfiguring Ethernet Switches; Installing Xpak Transponders - HP StorageWorks 9000 - Virtual Library System User Manual

Reconfiguring Ethernet Switches

Before installing the interswitch kit, establish a CLI session with each switch to ensure that Rapid
Spanning Tree Protocol (RSTP) is enabled.
1. Locate a null-modem (serial) cable provided with the VLS.
2. Connect one end of the serial cable to a PC or workstation and the other to the serial port on
the rear of an Ethernet switch in rack 1.
3. Establish a CLI session using a terminal emulation program, such as Windows Hyperterminal™.
4. At the prompt, select a baud rate between 9600 and 115200 with 8 data bits and no parity.
5. Press Enter twice to reach the command line, which reads HP ProCurve Switch [switch
number]#, where the switch number is 2510 24 or 2810 24G as appropriate.
6. Enter show spanning-tree. The screen displays the status of the spanning-tree protocol and
the options set.
This optional step serves as a check of the initial status before you make the change. If the status
of the protocol is Yes, you may skip this procedure.
7. At the command line, enter config. The command line now reads HP ProCurve Switch
[switch number](config)#.
8. Enter spanning-tree force-version rstp-operation.
9. Enter spanning-tree. This turns on the spanning-tree protocol as configured.
10. At the command line, enter exit.
11. Enter exit.
12. Enter exit.
13. A prompt asks if you want to log out. Enter y.
The switch logs off, and the spanning tree is now reconfigured to include the new switch.
14. Repeat this procedure for the remaining Ethernet switches in racks 1 and 3.
NOTE:
After reconfiguring the Ethernet switches, power down the entire VLS system. See
System for instructions.

Installing XPAK Transponders

The XPAK transponders (XPAKs) plug into the 10 Gb Fibre Channel ports in the front of Fibre Channel
Switches 4/16q. Fibre Channel Switches 4/16q are included in the 32 port connectivity kits. See
Figure 23.
