Removing and Replacing the Ethernet Switches
The following procedure replaces the procedure found in Section 9.2.1 and 9.2.2 of
the Sun Technical Compute Farm Installation and Service Manual.
Note – When removing or replacing the Ethernet switches, a nonconducting step
ladder and a flashlight might be required. Refer to the Cisco AS2509-RJ and AS2511-
RJ Access Server Hardware Installation Guide and the Cisco Catalyst 3500 Series XL
Installation Guide for complete details.
Note – The procedures to remove and replace the C3508 Ethernet switch are
identical to those for the C3524 Ethernet switch. The C3524 and C3508 Ethernet
switches are now mounted facing the rear of the rack.
Caution – Never remove or replace a device when system power is on.
To Remove an Ethernet Switch
1. Unlock, open, and remove the rack door(s) as appropriate.
2. Power off the system.
Refer to Chapter 6 in the Sun Technical Compute Farm Installation and Service Manual.
Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in
antistatic bags before placing them on any surface.
3. Remove the 4RU filler panel from the front of the rack (above the top compute
engine).
4. Disconnect the power cable from the back panel of the Ethernet switch as
described in the Cisco Catalyst 3500 Series XL Installation Guide.
5. From the back of the rack:
a. Disconnect the Ethernet switch cabling.
Refer to Chapter 5 in the Sun Technical Compute Farm Installation and Service
Manual.
b. Using a No. 2 Phillips screwdriver, loosen the back mounting screws securing
the Ethernet switch chassis to the mounting plate (
