Opening and Closing the HP Server tc4100
Introduction
This section describes how to safely extend the rack-mounted HP Server tc4100 out of the rack and how to
remove and replace the covers from the HP Server tc4100 either rack-mounted or in the pedestal. This section
also describes how to remove and replace the pedestal base from the HP Server tc4100.
Tools Required
Antistatic service kit (3M™ 8501/8502/8503 or equivalent). This kit includes a static-dissipating work surface,
a chassis clip lead, and a wrist strap.
Removing the HP Server tc4100’s Covers
The HP Server tc4100’s covers are designated top and bottom for the rack-mounted version and left and right
for the pedestal version.
Removing Covers – Rack-Mount
Use this procedure to remove the bezel and then safely extend the Server to where you can remove the covers
(top and bottom) from the HP Server tc4100.
• If you are installing hardware options, you must remove the front bezel, extend the Server, and remove the
top cover. The hardware options include not-hot swap drives, common-tray drives, accessory boards,
DIMMs, and an additional processor, which require access to the interior of the Server.
• If you are only installing or removing hot-swap SCSI disk drives, remove the bezel, but do not extend the
Server or remove the covers.
• If you are only installing the redundant power supply, you do not need to remove the bezel, extend the
Server or remove the covers.
3 Installing and Configuring
WARNING Before removing the covers, shut down the operating system and disconnect the power
cords and unplug telephone cables. Disconnect the power cords to avoid exposure to high
energy levels that may cause burns when parts are short-circuited by metal objects, such
as tools or jewelry. Disconnect telephone cables to avoid exposure to a shock hazard from
telephone ringing voltages.
WARNING To prevent injury or system damage, do not operate the HP Server tc4100 with its covers
or front bezel removed, or install items with the power cord connected.
Always disconnect the power cord before removing any covers, to avoid exposure to high
energy levels that may cause burns when parts are short-circuited by metal objects such
as tools or jewelry. Disconnect any telephone cables to avoid exposure to shock hazard
from telephone ringing voltages.
CAUTION To prevent overheating, never operate the Server with its covers removed. This includes
the power supplies and Hot Swap hard disks, which must be replaced or the opening
covered immediately (within 2 minutes).
