Goal

How to remove and replace a Starcat AC Module

Solution

CAP PROBLEM OVERVIEW: Centreplane to be replaced.

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
Starcat training, familiarity with SMS command set

DELIVERY REQUIREMENT:
This procedure requires an extended outage on all domains, to be negotiated with the customer during contract hours.

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

1. Ensure SC failover is enabled and all data in in sync ("showfailover; showdatasync").
2. All domains should be shut down to the OBP ("ok prompt"), then powered off using "setkeyswitch -d X off".?

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Removing a Power Module:

1. Both SCs should also be brought to the ok prompt before switching all 12 power supply breakers to the OFF position.
2. Confirm above actions are taken. Frame needs to be powered down completely.
3. Route I/O cables away from the power module, ensuring not to disconnect any cables.
4. Label and disconnect the twelve AC power cords with the labels provided in the shipping kit.
5. Remove the power supplies from the power module.
6. Remove the air-plenum cover by removing the eighteen M4x35 panhead screws from the top, sides, and bottom of the air-inlet screen.
   Caution – The seven power cables and the two control cables MUST BE REMOVED from the system chassis on both the front and rear sides of the system prior to removing the power module.
7. Loosen the jackscrews on the seven 8W8 Combo-D 8-pin DC power connectors (on the left side) and the two DB-25 control connectors (on the right side).
8. Disconnect the cables from the mounting bulkhead of the system chassis.
9. Remove the four M4x10 panhead screws attaching the power module front flanges to the system chassis.  With one person on each side of the power module, grasp the front (at the power supply opening) and the bottom and slide the power module outward from the cabinet.
10. Place the power module on a flat sturdy surface.
11. From the top rear of the power module, loosen the seven 8W8 Combo-D 8-pin DC power connectors (on the left side) and the two DB-25 control connectors (on the right side).

 Installing a Power Module:

1. Follow the removal procedures in reverse order.
2. Monitor SC bootup and SMS startup.
3. Enable SC failover.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
