WARNING Disconnect the system and peripheral devices from AC power before servicing internal
components! Failure to remove AC power may result in equipment damage or personal
injury.
WARNING Follow all warnings and cautions in the servicing instructions. If you fail to follow
documented, approved procedures, personal injury and damage to equipment can
result.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge.
“Right side” and “left side” are as seen from the front of the unit.
Tools
You will need the following tools to service the system:
u
Antistatic wrist strap
u
Quarter-inch nutdriver
u
No. 1 and No. 2 Phillips screwdrivers
u
Three-sixteenth-inch nutdriver
u
Five-sixteenth-inch or 8 mm nutdriver
u
Small single-slot screwdriver
Avoiding Electrostatic Discharge
Sensitive components inside the base unit can be damaged by static electricity. To protect
against this possibility, take the following precautions when working with internal
components.
u
Unplug the unit from AC power before servicing any electronic component inside the
chassis.
u
Touch the bare metal of the base unit to ensure the base unit and your body are at the
same electric potential.
u
Handle all printed circuit boards as little as possible and by the edges only. Leave new
parts in their protective packaging until you install them.
u
Use a disposable or reusable antistatic wrist strap when servicing or upgrading the system.
Once a disposable wrist strap is used, it cannot be used again.
u
A reusable antistatic wrist strap can be attached to any bare metal part of the base unit.
The metal conductor in the elastic sleeve of reusable antistatic straps must contact bare
skin.
Opening the Base Unit
CAUTION Before you open the base unit, shut down the system and turn off power to the system and
external devices (including peripheral drives and display). Use caution to avoid injury when
removing covers and other hardware.
CAUTION Ensure the front and side stabilizers of the rack in which the system is moun ted are fully
extended.
To open the base unit:
1. Remove the screws that secure the handles to the rack.
2. Disconnect all cables including the power cable, monitor, and all peripheral cables from
the back of the unit.
3
3. Slide the base unit out of the rack until it locks in the extended position.
4. Remove and retain the two screws that secure the cover to the chassis: one each on the
upper left and right corners of the back of the chassis.
5. Slide the cover back about an inch, then lift the cover off.
6. Attach the grounding clip from the antistatic wrist strap to bare metal.
Opening and Closing the Face Panel
To open the face panel:
1. Loosen the two thumb screws that secure the face panel to the base unit (on the upper
right and left corners of the face plate).

JBOD or RAID Disk Drives
The disk drive bay may contain up to four non-RAID (JBOD) or RAID drives. The
replacement procedure for these drives is similar.
To replace disk drives:
1. Open the drive access door on the front of the system.
2. Flip the drive latches outward to disengage the disk drive. Wait 30 seconds to allow the
drive to spin down and park the heads.
3. Carefully eject the drive completely from the rails, and remove it from the disk drive
section.
WARNING Handling a spinning drive or mishandling a removed drive can cause the heads to
crash! Subsequent failures may not be noticeable for three to six months. Handle disk
drives carefully to avoid damage.
4. Remove the drive mounting plate from the removed disk drive, making sure to retain the
mounting plate screws. Attach the mounting plate to the bottom (circuit board side) of the
new drive, using the four screws you retained from the removed drive.
WARNING Removing and attaching the drive mounting plate requires careful handling to avoid contact
with the delicate, electrostatic-sensitive parts on the circuit board of the drive. All drives must
be handled carefully to prevent failure and voiding the warranty for the drives.
