NOTE: If a module slot is to be left empty, the filler plate (provided) must be installed.
Installation of the filler panel is necessary for proper cooling inside chassis.
•
SCSI I/O Connectors - The DS550 chassis is unwired and comes equipped with
rear panel cut-outs for up to six (6) I/Os.
• Power Supply Module(s) - Dual auto-ranging power supply modules run in
Shared Mode which allows both to operate at reduced wattage and lower operating
temperature. In the event that one power supply should fail, the other will carry the
full load.
Blower Vent(s) - Two (2) adjustable dual-speed blowers (one in each power
supply module) provide ample cooling of chassis (79 CFM Total).
Module Handle(s) - Provide a sturdy grip for the installation and removal of the
power supply modules.
WARNING: DO NOT USE MODULE HANDLES TO LIFT CHASSIS! These
handles are specifically designed for the installation and re-
moval of modules only!
Power Switch(es) - Rocker switch(es) control power to the power supply
module(s).
A/C Power In - Accepts U.S. and other available international standard power
cords.
Blower Speed Selector Switch(es) - Allow user to manually select between two
speeds (Low & High) for each blower. High speed (factory default) is recommended
for high performance (10K RPM and higher) drives.
NOTE: In the event a blower fails, always set the speed of the remaining blower
to High.
Status LED(s) -
Green = Steady glow indicates normal power supply/blower operation.
OFF = No glow indicates a fault in either the power supply or blower
(or both). Refer to the Indicator and Control Panel LEDs on the
front of the DS550 for further information.
