ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
10.0 Hardware Maintenance
The disk drive sleds, blower assemblies, power supplies, host interface cards, and system management
card may be replaced with identical or upgraded parts.
CAUTIONCAUTION
Do not leave empty openings on the front
or rear of the Diamond-VT under any
circumstances. Empty openings affect
airflow and may cause the unit to overheat
and shut down.
WARNING
The only way to completely de-energize the
unit is to turn off both
power supplies and
unplug both power
cords from the back of
the unit. Turning the
power switch to the
Stand-by position on one power supply
does not completely turn off power to the
Diamond-VT; it is not an AC on-off switch.
Power may still be in the unit through the
other power supply.
CAUTIONCAUTION
All modular components must be replaced
by qualified personnel only. Use a static
wriststrap when handling any of the cards
inside the Diamond-VT. Components are
electrostatic sensitive. Use proper
grounding methods when working with or
around the Diamond-VT. Always store
spare components in proper ESD
containers when not in use.
• The power supply and blower assembly may be
replaced while the unit is running. (See
Hot Swap
Operating Instructions

• Host interface cards and management cards
may only be replaced when the Diamond-VT is
off. Backup the unit fully before replacing these
components.
• You may remove a disk drive sled while the
Diamond-VT is powered on. See the instructions
in

on page 69 for
