Replacing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D power interlock switch with the power off

Use this procedure to replace the power interlock switch with the power off.

Before proceeding with this procedure, you must have already completed the procedure Removing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D power interlock switch with the power off.

If your system is managed by the Hardware Management Console (HMC), use the HMC to complete the steps for replacing the power interlock switch in the server. For instructions, see Exchanging a part by using the Hardware Management Console. If you do not have an HMC, complete this procedure to replace the power interlock switch.

Note: Check the display on your control panel to see if your system is managed by the HMC. If you do not see HMC displayed, your system has not ever been connected to the HMC. A display of HMC=0 indicates that your system does not currently have the HMC. If the HMC display equals a number greater than 0, your system has the HMC.

If your system is managed by the IBM® Systems Director Management Console (SDMC), use the SDMC to replace the power interlock switch in the server. For instructions, see Replacing a part by using the Systems Director Management Console. If you do not have an SDMC, complete this procedure to replace the power interlock switch.

To replace the power interlock switch with the power off, complete the following procedure:

Perform the prerequisite tasks as described in Before you begin.
If necessary, remove the new power interlock switch from its packaging.
Reconnect the signal cable to its attachment location on the system board (C).
Figure 1. Replacing a power interlock switch in a rack-mounted system

Figure 2. Replacing a power interlock switch in a stand-alone system
Slide the switch mechanism hole (A) over the side screw holds (B) until it latches into place.
Replace the service access cover:
- For a rack-mounted system, see Installing the service access cover on a rack-mounted model.
- For a stand-alone system, see Installing the service access cover on a stand-alone model.
For a rack-mounted system, place the system into the operating position. For instructions, see Placing a rack-mounted model into the operating position.
To verify the repair, start the system. For instructions, see Starting the system or logical partition. If the switch was installed correctly, the system operates normally.

Note: If a ball or dot appears in the middle of the control panel, toggle between function 02 and function 01 through the Operations Console or through the Hardware Management Console (HMC) until the ball or dot disappears. Systems managed by the HMC should use the HMC to perform control panel functions. For more information about the control panel, see Control panel functions.
