4.2 Replacing Subsystem Components
CAUTION: When replacing the components of the subsystem, make
sure to handle the parts carefully. When handling ESD sensitive
parts such as boards or PCBA, it is recommended to use anti-static
hand gloves or wrist strap.
Make sure somebody is around to give help when servicing the
subsystem.
Take note of the following when replacing the components of the subsystem.
Hot Swappable
(Subsystem is online)
Need to Power Off
(Subsystem should be offline)
Disk Drive Trays
Front Panel
Power Supply
Bottom Board
JBOD Controller
(dual controller mode)
JBOD Controller (single controller mode)
SAS Expander (dual controller mode)
SAS Expander (single controller mode)
Turbo Fan (Fan 06-1)
IMPORTANT:
(1.) When the subsystem is online and a Power Supply fails, and
the replacement Power Supply module is not yet available, don’t
remove or disconnect the failed Power Supply module. This is to
maintain proper airflow within the enclosure, since the fans will
still be working.
(2.) When the subsystem is online and a Controller module or SAS
Expander module fails and the replacement is not yet available, in
order to maintain proper airflow within the enclosure, the failed
module can be disconnected just about an inch but not entirely
removed from the slot. This is to maintain proper airflow within
the enclosure.
(3.) When replacing a failed component online, it is not
recommended to remove the failed component for a long period of
time; proper air flow within the enclosure might fail causing high
controller / disk drive temperature.
