Exchange the CEC enclosure service processor or time of day battery

Before you begin

Icon for electrostatic discharge wrist strap Use approved ESD procedures to prevent damage.

Attention:

This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.

Notes:

All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

Remove the service processor or battery

Procedure

Was this screen displayed after selecting a serviceable event repair option or an Exchange Parts menu option?
- Yes, go to the next step.
- No, STOP! Customer disruption, hardware damage, incorrect firmware and VPD settings may occur if microcode and power boundaries are not in the proper conditions for this service action. Use one of the above options to replace this part.
Is the FRU container security seal broken?
- No, go to the next step.
- Yes, you must not install this part. Obtain a new service processor with an unbroken security seal and then go to the next step.
Note: A broken security seal indicates this service processor may have been installed in a CEC enclosure. If it was, the card VPD is no longer in the reset state, and the repair action will fail. There is no field process to reset the card VPD. The card must be returned to IBM® for reset and not as a failed FRU.
Verify that the CEC enclosure is in the "power off" state before you continue. (The CEC enclosure should already be in the power off state.)
Note: If this FRU has a FRU identify indicator LED, it is no longer lit.
If you have not already located the FRU to be replaced, use the location code listed in the serviceable event FRU list. See MAP1245 Finding FRUs by using location codes.
At the rear of the storage facility, view both CEC enclosure power supplies.
Figure 1. CEC enclosure DC good LEDs

Are both DC GOOD LEDs flashing?
- Yes, continue with the next step.
- No, do not continue with this FRU replacement. Go to MAP4840 CEC enclosure fails to power off during CEC enclosure parts exchange to fix the problem with the CEC enclosure not being in the power off state.
Use a replacement part with a valid DS8000® part number to ensure that the DS8000-unique firmware is already installed and configured.
Attempting to use a generic part from an eServer™ will fail and complicate the repair.
Remove all power from the CEC enclosure.
- At the rear of the CEC enclosure, disconnect the power input cables to both CEC enclosure power supplies.
- At the CEC enclosure control panel, observe the green Power® Present icon, beneath the white Power button.
  - If it is slow flashing, the CEC enclosure is still in the power-off state. DO NOT CONTINUE. Ensure that you have unplugged the power cables.
  - If it is off, go to the next step.

Remove the service processor. See Figure 3.
Figure 3. Removing the service processor card
1. Disconnect all cables connected to the service processor.
2. Press the thumb release on the service processor to unlock the handle.
3. Pull the handle to the right to unseat the service processor.
4. Pull the service processor from the I/O backplane assembly using the handle and supporting the bottom of the card.
If replacing the battery, do the following:
1. Locate the battery on the service processor.
  Note: Do not bend the tab up when you remove the battery. Use tweezers or needle nose pliers to remove the battery. Be careful not to damage the tab's surface plating where it contacts the battery.
2. Remove the time-of-day battery from the service processor as shown in Figure 4.
  CAUTION:
  The battery contains lithium. To avoid possible explosion, do not burn or charge the battery.
  Do not:
  
  Throw or immerse into water.
  
  Heat to more than 100-degrees C (212-degrees F).
  
  Repair or disassemble.
  Exchange only with the IBM-approved part. Recycle or discard the battery as instructed by local regulations. In the United States, IBM has a process for the collection of this battery. For information, call 1-800-426-4333. Have the IBM part number for the battery unit available when you call. (C003)

  Note: Before installing the replacement battery, support the short horizontal section of the tab with needle nose pliers while simultaneously pressing the end of the tab down to increase the tension on the battery.
3. Before replacing the battery, ensure that the positive (+) side of the battery is facing up.
4. Insert the battery into its mount.
If replacing the service processor card, and the new card does not have a VHDM EMC cover, do the following:
1. Remove the EMC cover located on the right front of the old service processor card. See Figure 5.
  Figure 5. Service processor card VHDM EMC cover
2. Install the EMC cover on the new service processor card.
If replacing the service processor card, and if the new card has a cover for the P1-I2C connector, remove and discard it. See Figure 6.

Install the service processor

Procedure

Install the service processor.
1. Slide the service processor all the way into the card slot in the system enclosure.
2. Push the handle toward the service processor until the release tab locks the handle in place. This will secure the service processor into the card slot. See Figure 3.
Reconnect the cables to the service processor.
At the rear of the CEC enclosure, connect the power input cables to both CEC enclosure power supplies.
Ensure that the CEC enclosure is in the power-off state before you continue. At the CEC enclosure control panel, wait for the green Power Present icon, beneath the white Power button to slow blink, and then continue the repair.
