Control Panel and front panel LED's may be functioning), and air is flowing
from the power supply cooling fan grill on the rear of the library, observe the
"Green" LED (lowest of the three). If it is lit, the power supply is OK.
Note: If your library has -04 level redundant power supplies (see label on top
of power supply), it is normal for the one in "Standby" mode to turn its
"Green" LED off. You can test this power supply by pulling the power
connector from the other "Active" power supply. The power supply that
was in "Standby" mode will now become "Active", and its "Green" LED
should light. If it doesn't, replace it (refer to "Replacing a Power Supply"
on page 10-7).
If your library has -05 level redundant power supplies, the "Green" LED
will be ON on both power supplies. If both "Green" LEDs are not ON,
replace the failed power supply (refer to "Replacing a Power Supply" on
page 10-7).
