New Position of Cisco Networking Devices
The Cisco C3524 and C3508 Ethernet switches have been repositioned and reversed
in the Sun TCF base and star rack configurations. In both configurations, the C3524
is now mounted below the two terminal server units and faces the rear of the rack.
For the star rack configuration, the C3508 is mounted below the C3524 and faces the
rear of the rack.

Removing and Replacing the Rack Front and Back
Doors
Use the following procedure to remove and replace the rack front and back doors.
This section supplements the information in Chapter 3 of the Sun Technical Compute
Farm Installation and Service Manual.
▼ To Remove a Rack Door
1. Reach inside the door and push down on the lever attached to the spring of the
top hinge pin.
This causes the hinge pin to retract into the door.
2. Tilt the door out from the top mounting bracket.
3. Remove the door and set it aside.
▼ To Replace a Rack Door
1. Tilt the door and insert the bottom hinge pin into the outside hole of the bottomleft mounting bracket.
2. Reach inside the door and push down on the lever attached to the spring of the
top hinge pin.
This causes the hinge pin to retract into the door.
3. Align the top hinge pin with the outside hole of the top-left mounting bracket.
4. Release the lever.
The hinge pin extends into the mounting bracket.

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 terminal server back panel as described in
the Cisco AS2509-RJ and AS2511-RJ Access Server Hardware Installation Guide.
5. From the back of the rack:
a. Disconnect the terminal server 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 terminal server chassis to the mounting plate (FIGURE 7).
6. From the front of the rack:
a. Using a No. 2 Phillips screwdriver, remove the front mounting screws securing
the terminal server chassis to the mounting plate (FIGURE 7).
b. Remove the terminal server from the rack.
