Exchange the UPS

Before you begin

CAUTION:

This assembly contains mechanical moving parts. Use care when you service this assembly. (C025)

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 UPS

Procedure

The UPS FRU should have arrived with a new battery FRU, in a separate box. Check the date labels on the FRU packaging or on the front of the new battery FRU.
1. Record the "Install / Recharge by: " date for reference at a later screen.
2. Record the "Battery Mfg. Date" for reference at a later screen.
  
  Note: Both dates appear in the format YYYY-MM-DD. Later in this repair you will be asked to enter the "Battery Mfg. Date" in the format YYYYMM.
3. Has the "Install / Recharge by: " date passed?
  Yes. The date has passed. Stop the repair. You cannot continue with an expired battery FRU.
  - Click Close to close the parts exchange procedure.
  - When asked, "Has the part been replaced?", click OK.
  - When directed to check "Install / Recharge by: " date, click Exit to exit the service action.
  No. The date has not passed. Continue the repair.
Locate the UPS to be replaced.
1. There is no FRU identify LED indicator for the UPS.
2. The UPS is part of the storage controller module, the group of enclosures shown in Figure 1.
3. You must use the FRU location code information to locate the FRU.
  
  The location code is in the format Unnnn.mmm.ssssss-E6y. Example:
  nnnn = machine type
  mmm = model
  sssssss = storage facility serial number (Not the serial number of the customer-provided rack.)
  y = 1 (upper), 2 (lower)
  See Figure 1.
4. Use the storage facility serial number label on the front of the management enclosure to confirm.
Figure 1. Storage controller module (enclosures shown)

2. Wait 30 seconds. Is the UPS control panel output status green LED indicator off? See Figure 3.
  Note: The control panel displays oFF status.
  - Yes. Go to step 4 to disconnect the input power cable.
  - No. The UPS cannot power down normally. Go to step 4 to force power off (by disconnecting the input power cable).
At the rear of the UPS, unplug the input power cable from J10. See Figure 4.

Warning: An immediate customer outage will occur if the input power cable is unplugged from the wrong UPS.

Note: The UPS is temporarily powered by the battery until the "On battery" condition times out.
Remove the UPS front panel and disconnect the control panel cables from the UPS.
1. Remove the four screws. See Figure 6.
  
  Note: The screws are small and are not fastened to the front panel. Use caution to avoid dropping the screws.
2. Partially remove the front panel.
3. Disconnect the control panel cables from the UPS.
  
  Note: Handle with care to avoid damaging the connecting cables.
4. Remove the UPS front panel. It is reinstalled on this UPS after the battery is removed from the UPS and the UPS is removed from the rack.

Note: The battery is returned or disposed of separately. The old battery is not reused.

Transfer network card from old to new UPS

Procedure

At the rear of the UPS, remove the network card (C1). See Figure 4.
1. Remove the dust plug from C1-J2.
2. Remove the two screws.
3. Remove the black plastic bezel.
4. Remove the network card. Note the orientation of the network card.
  
  Note: If the card is hard to remove, a spare Ethernet cable can be connected to the network port (C1-J1) and pulled to remove the card.
Note: The network card is hot-plugged. The UPS stays fully operational.
To install the network card in the new UPS, reverse the steps above.

Transfer UPS 1U side rails from old to new UPS

Procedure

If the new UPS did not come with side rails pre-installed, transfer the rails from the old UPS to the new UPS.
Each rail is fastened with 10 screws . See Figure 14.

Install the side rails on the new UPS.

Install the UPS

Procedure

Temporarily remove the front panel from the new UPS FRU. Set it aside.
1. Remove the four screws. See Figure 6.
  
  Note: The screws are small and are not fastened to the front panel. Use caution to avoid dropping the screws.
2. Partially remove the front panel.
3. Disconnect the control panel cables from the UPS.
  
  Note: Handle with care to avoid damaging the connecting cables.
4. Remove the UPS front panel.
If spare labels were provided with the FRU kit, create a system serial number and UPS location cable label to affix to the top from edge of the new UPS.

2. Find the blank label shipped with the new UPS.
3. Write the system S/N and UPS location on the new label. Fasten it to the new UPS in the same location as the old UPS.
Figure 15. Storage facility serial number label location
Ensure that the new UPS does not have a battery installed. The new battery FRU is in a separate box.

Note: If the new FRU has a battery installed, remove it.
Install the new UPS (without battery) in the rack and fasten with the two screws . See Figure 13.

CAUTION:
The combined weight of the UPS with battery exceeds the single-person weight limit.
At the rear, install the four screws. Ensure that the cable tie bar is in the upper position.
At the front of the new battery FRU, check the front label(s) if you have not already done so.
1. Record the "Install / Recharge by: " date for reference at a later screen.
2. Record the "Battery Mfg. Date" for reference at a later screen.
Note: Both dates appear in the format YYYY-MM-DD. Later in this repair you will be asked to enter the "Battery Mfg. Date" in the format YYYYMM.
