This MAP is the entry point to the MAPs for the 7031-D24 or 7031-T24.
If you are not familiar with these MAPs, read Using the MAPs first.
You might have been directed to this section because:
- The system problem determination procedures sent you here.
- Action from an SRN list sent you here.
- A problem occurred during the installation of a 7031-D24 or 7031-T24 or a disk drive
module.
- Another MAP sent you here.
- A customer observed a problem that was not detected by the system
problem determination procedures.
Attention: Do not remove power from the host system or 7031-D24 or 7031-T24 unless you are
told to in the instructions that you are following. Power cables and
external SCSI cables that connect the 7031-D24 or 7031-T24 to the host system
can be disconnected while that system is running.
- Does the 7031-D24 or 7031-T24 emit smoke or is
there a burning smell?
- Are you at this MAP because power is not removed
completely from the 7031-D24 or 7031-T24 when the host systems
are switched off?
Note: Power will remain on the 7031 for approximately
30 seconds after the last system is powered off.
- No
- Go to step 3.
- Yes
- Go to MAP 2030: 7031-D24 or 7031-T24 power control.
- Have you been sent to this MAP from an SRN?
- No
- Go to step 4.
- Yes
- Go to step 7.
- Have the system diagnostics or problem determination
procedures given you an SRN for the 7031-D24 or 7031-T24?
- No
-
- If the system diagnostics for the 7031-D24 or 7031-T24 are available,
go to step 5.
- If the system diagnostics for the 7031-D24 or 7031-T24 are not available,
but the stand-alone diagnostics are available, do the following:
- Run the stand-alone diagnostics.
- Go to step 6.
- If neither the system diagnostics nor the standalone diagnostics
are available, go to step 7.
- Yes
- Go to Service request numbers.
- Run the concurrent diagnostics to the 7031-D24 or 7031-T24. For information
about how to run concurrent diagnostics, see Running
the online and stand-alone diagnostics.
- When the concurrent diagnostics are complete, go to step 6.
- Did the diagnostics give you an SRN for the 7031-D24 or 7031-T24?
- No
- Go to step 7.
- Yes
- Go to Service request numbers .
- Is the subsystem check LED flashing?
- No
- Go to step 8.
- Yes
- A device is in Identify mode. A power supply, SCSI card, or disk
drive module is to be added or installed.
- Is the subsystem check LED on continuously?
- No
- Go to step 12.
- Yes
- Go to step 9.
- Does the power-supply assembly have its FLT LED
on because its DC On/Off switch is set to Off?
- No
- Go to step 10.
- Yes
-
- Set the DC On/Off switch to On.
- If you still have a problem, return to step 2. Otherwise, go to MAP 2410: 7031-D24 or 7031-T24 repair verification to verify the repair.
- Does any FRU have its Check or Fault LED on?
Note: The
check LED might be on any of the following parts:
- A SCSI interface card assembly (CARD FAULT LED)
- A power-supply assembly (FLT LED)
- A fan assembly (CHK LED)
- A disk drive module (CHK LED)
- No
- In the following sequence, exchange the following FRUs for new
FRUs. Ensure that for each FRU exchange, you go to MAP 2410: 7031-D24 or 7031-T24 repair verification to verify the repair.
- SCSI interface card assembly (go to the 5786,
5787, and 7031 models D24 and T24 removal and replacement procedures ), and select the appropriate
part.
- Power supply (go to the 5786,
5787, and 7031 models D24 and T24 removal and replacement procedures ), and select the appropriate
part.
- Fan assembly (go to the 5786,
5787, and 7031 models D24 and T24 removal and replacement procedures ), and select the appropriate
part.
- Frame assembly (go to the 5786,
5787, and 7031 models D24 and T24 removal and replacement procedures ), and select the appropriate
part.
- Yes
-
- If the FRU is a fan-and-power-supply assembly, go to step 11. Otherwise, exchange the FRU whose
Check LED is on.
- Go to MAP 2410: 7031-D24 or 7031-T24 repair verification to verify the repair.
- Is the enclosure set up for remote power control
(that is, is the power control switch of the SCSI interface card assembly
set to Off)?
- No
-
- Exchange, for a new one, the power supply whose FLT LED is on
(go to the 5786, 5787, and 7031 models D24 and
T24 removal and replacement procedures ), and select Power supply.
- Go to MAP 2410: 7031-D24 or 7031-T24 repair verification to verify the repair.
- Yes
-
- Ensure that:
- The DC On/Off switch is set to On.
- Both ends of the SCSI cable are correctly connected.
- The host system is switched on.
- If the FLT LED of a power supply is still on, pull out the power
supply to disconnect it from the 7031-D24 or 7031-T24, then push it back
to reseat its connectors (go to the 5786,
5787, and 7031 models D24 and T24 removal and replacement procedures ), and select the appropriate
part.
- If the FLT LED is still on, exchange, in the sequence shown, the
following FRUs for new FRUs. Ensure that for each FRU exchange,
you go to MAP 2410: 7031-D24 or 7031-T24 repair verification to verify the repair.
- Power supply whose FLT LED is NOT on, (go to the 5786,
5787, and 7031 models D24 and T24 removal and replacement procedures ), and select Power supply.
- SCSI interface card
- Frame assembly
- Is the subsystem power LED on?
- No
- Go to MAP 2020: 7031-D24 or 7031-T24 power.
- Yes
- Go to step 13.
- Does either power supply assembly have its DC PWR
LED off when it should be on?
- No
- Go to step 14.
- Yes
-
- Exchange the power-supply assembly whose LED is off.
- Go to MAP 2410: 7031-D24 or 7031-T24 repair verification to verify the repair.
- Are you here because access to all the SCSI devices
that are in the 7031-D24 or 7031-T24 has been lost?
- No
- No problem has been found on the 7031-D24 or 7031-T24. For a final check,
go to MAP 2410: 7031-D24 or 7031-T24 repair verification.
- Yes
- Go to MAP 2340: 7031-D24 or 7031-T24 SCSI bus.
