The
Private\DriveBay\Power Left
or
Right
status screens display the sta-
tus of all power supply modules. The right (as viewed from the front of the RLS) mod-
ule is only found on models with dual-redundant power supply modules installed. The
left power supply status screen also covers all single module supplies. All 250-watt
modules contain two identical 24VDC, 125-watt power supplies called A and B and
thus the reasons for Alarms A & B.
All power supply modules are or’ed together so that it’s po ssible to have a power sup-
ply fail and still have power to run the processors to get out an Alarm message over e-
mail using the Q-Link remote manager.
The following data is displayed on the
Private\DriveBay\Power ?
screens:
• Type
Description of the Power Supply Module(s) installed (see Table Table 5-6).
• Alarm A or B
OFF
is normal.
ON
indicates a failure of power supply A or B within the
Left
or
Right
module.
