Both leds on a BA356 8 bit I/O modules were lit again this morning on one
of our BA-356. The system cabinet is pretty full, but we have air
conditionning in the machine room and the air is cool. According to the
manuals, this situation means that both blowers are running at high speed.
Is this a normal situation ? Should we expect the leds to go off after a
certain amount of time ?

This only appear on ONE shelf out of 7 shelves. All of our shelves are
equipped with 2 power supplies.

On all the 2 power supplies shelves, both green leds on each power supply
are lit up (which is the normal situation).

We were wondering if there was a bug in the doco for SINGLE power supply
equipped shelves: On our single power supply shelf, only ONE led is lit up
(the bottom one) Accordin to the doc, this indicates that the power supply
is OK but that there is a shelf fault. The devices connected to that shelf
seems to operat normally. This shelf is splitted in two and contains a TZ87
and a TZ88. One of the drives is ID 2 and the other is ID 5, each of 2
alpha servers are connected to this shelf via a KZPAA.
