Procedures for switch assemblies

CAUTION:

The unit weight exceeds 18 Kg (40 lbs) and requires two service personnel to lift. (SPSFC002)

Attention: Components in the frame are susceptible to damage from static discharge. Always use an ESD wristband when working inside frame covers. (See ªPersonal ESD requirementsº on page 3-1 for more details.) Do not touch the pins or circuitry on these components.

Note

There are different levels of the switch assembly hardware. The following lists indicate serviceable FRUs for each level of switch assembly:

SPS Fans, circuit breaker, LED card, switch supervisor card, switch power card(s), fan assembly cable, supervisor/power cable, complete assembly.

SPS-8Fans, circuit breaker, LED card, switch supervisor card, switch power card(s), fan assembly cable, supervisor/power cable, complete assembly.

Removing the switch assembly

Perform these procedures to remove the switch assembly:

1.Ensure that the switch is offline (shutdown) from the control workstation and powered off from the control workstation.

Attention: Removing power from one switch assembly may affect other switch assemblies and processor nodes attached to it.

2.Turn the power switch on the switch assembly to Off (`0').

3.Detach all cables from rear of switch assembly noting where external frame cables are attached. If wrap plugs are installed, remove them and save for the new switch.

4.If this is a switch drawer (in multi-switch frame F/C 2030/1) and you are replacing the switch assembly, remove the two screws at the rear of the switch assembly.

5.Remove four screws from front of switch assembly and slide switch assembly out of the front of the frame.

6.Remove the front chassis and then remove the inner chassis from the outer chassis sleeve.

7.Return to the procedure that directed you here.

Replacing the switch assembly

Perform these procedures to replace the switch assembly:

1.Replace the inner chassis into the outer chassis sleeve and then replace the front chassis.

2.If wrap plugs are installed, they can be plugged on the new switch.

3.Slide switch through the front of the frame and reinstall four screws that hold the switch to the frame.

4.If this is a switch drawer (in F/C 2030/1) and you are reinstalling the switch assembly, reinstall the two screws at the rear of the switch assembly.

5.Reattach all cables to rear of switch assembly.

6.Turn the power switch on the switch assembly to On (`1').

7.Refer to ªRestoring a switch assembly to the active configurationº on page 3-8.

8.Return to the procedure that directed you here.
