v AC module (see symbolic FRU “ACMODUL” on page 268) or battery charger unit (see symbolic
FRU “BATCHGR” on page 285)
v System unit control panel cable
v Power supply (see symbolic FRU PWRSPLY). With a new unit, replace one of the power
supplies 1, 2, 3, or 4 as installed until the failing unit is found.

c.
Reconnect the mainline ac power cables to the power outlet.
d. Attempt to power on the system.
e. If the system powers on, the FRU you exchanged is the failing item.
f. If the system does not power on, repeat steps 7a (See page 35) through 7f (See page 36), and
exchange the next FRU in the list. If the system does not power on after exchanging all of the
FRUs in the list, ask your next level of support for assistance.
This
ends the procedure.
- DANGER
Dangerous voltage being measured. (RSFTD005)
Perform the following:
1. Disconnect the ac power jumper cables from the ac module or battery charger unit.
2. Use a multimeter to measure the DC voltage (from battery charger) or ac voltage (from ac module)
at the outlets to the power supplies.
Is the DC voltage from 145 V DC to 259 V DC for the battery charger unit, or 200 V ac to 240 V ac for
the ac module (dual line cord)?
v Yes: Continue with the next step.
v No: Exchange the battery charger unit (see symbolic FRU “BATCHGR” on page 285) or ac module
(see symbolic FRU “ACMODUL” on page 268).
This
ends the procedure.
- DANGER
Dangerous voltage being measured. (RSFTD005)
Perform the following:
1. Connect the ac power jumper cables to the battery charger or ac module.
2. Disconnect the ac power jumper cable at the power supplies.
3. Use a multimeter to measure the DC voltage (battery charger) or ac voltage (ac module) at the
power jumper cables input to the power supplies.
Is the DC voltage from 145 V DC to 259 V DC (200 V ac to 240 V ac for dual line cord units) for each
power jumper cable?
v No: Exchange the power jumper cable.
This
ends the procedure.
v Yes: Exchange the following parts one at a time.
– SPCN card unit (see symbolic FRU “TWRCARD” on page 470).
– Display unit (see symbolic FRU “CTLPNL” on page 323).
– Power supply (see symbolic FRU “PWRSPLY” on page 431). With a new unit, replace one of the
power supplies 1, 2, 3, or 4 until the failing unit is found.
This ends the procedure.
-
Perform the following:
1. Power off the system.
