Error code Description Action
005100A No usable memory detected.
1. Make sure that the server contains DIMMs.
2. Reseat the DIMMs.
3. Install DIMMs in the correct sequence (see
“Installing a memory module” on page 89).
4. Clear CMOS memory to re-enable all the memory
connectors (see “System-board switches and
jumpers” on page 31).
0058001 PFA threshold exceeded
1. Update the server firmware to the latest level (see
“Updating the firmware” on page 151).
2. Reseat the DIMMs and run the memory test (see
the Hardware Maintenance Manual).
3. Replace the failing DIMM, which is indicated by a
lit LED on the system board.
0058007 DIMM population is unsupported.
1. Reseat the DIMMs, and then restart the server.
2. Remove the lowest-numbered DIMM pair of those
that are identified and replace it with an identical
pair of known good DIMMs, then restart the
server.
3. Return the removed DIMMs, one pair at a time, to
their original connectors, restarting the server after
each pair, until a pair fails. Replace the DIMMs in
the failed pair with identical known good DIMMs,
restarting the server after each DIMM is installed.
Replace the failed DIMM. Repeat this step until
you have tested all removed DIMMs.
4. (Trained service technician only) Replace the
system board.
0058008 DIMM failed memory test.
1. Reseat the DIMMs, and then restart the server.
2. Replace the following components one at a time,
in the order shown, then restart the server after
each:
a. DIMM
b. (Trained service technician only) System
board
00580A1 Invalid DIMM population for mirroring mode
1. If a fault LED is lit, resolve the failure.
2. Install the DIMMs in the correct sequence (see
“Installing a memory module” on page 89).
00580A4 Memory population changed. Information only. Memory has been added, moved, or
changed.
00580A5 Mirror failover complete Information only. Memory redundancy has been lost.
Check the event log for uncorrected DIMM failure
events.
