Swap power between the failing switch and another one in the stack, see if the problem moves?

On that note... does this ring any bells?

Have a 3750E that has had spurious reloads (4 since Friday), was
switch-1 of a 3-member stack, initially was the master, now switch-2 has
taken over as master.   Show version on the failing one just shows

The other members have 23-week uptimes.

There's no crashinfo in the logs, no "software forced reload" type
reload events.

TAC insists power was cut to the switch (four times?).

Stack members are in a pair of self-contained, self-cooling Liebert
racks, 240v PDUs, different phases of a 3-phase supply, dual UPS,
generator backup, it's your "above average" server room.  There are
dozens of servers in these racks (3 x 48-port 3750Es full, mostly
dual-connected) and nothing has burped whatsoever.

Running 12.2(53)SE2 IPServices.  Stack has been up almost 6 months
(switch-3, a 3750X, was added about 4 months ago and has a 19-week
uptime).  No incidents until Friday, and no changes then that we can
identify.
