Notice to Service Technicians
This is the service document for the HP NetServer LC2000 server. You also need to access the HP
NetServer LC2000 Installation Guide which comes with the server and is also available on the Network
Server Division WEB site and on the Information Assistant Documentation CD-ROM.
The LC2000 installation guide contains additional information on the installation process which the end users
follow. Both documents are needed for complete servicing information.
Removing Covers - Pedestal (LC 2000)
Use this topic to remove the bezel and covers (left & right) on the HP NetServer LC 2000 (pedestal).
• If you are installing hardware options, you must remove the front bezel and top cover. The
hardware options include accessory boards, DIMMs, and an additional processor.
• If you are only installing hot-swap disk drive modules or a redundant power supply, you do not
need to remove the bezel or the covers.
l You do not need to remove the pedestal for access to the HP NetServer, but if you do need to
remove the pedestal, refer to Removing the Pedestal.
WARNING Do not operate the HP NetServer with its covers removed. 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.
1. If the HP NetServer is operating, log off all users and, if necessary, back up files.
2. Follow instructions in your network operating system (NOS) documentation to gracefully shut
down all networking software and applications.
3. Press the power switch on the HP NetServer's control panel when prompted by the operating
system.
Normally, this completes the power-down procedure.
CAUTION To prevent overheating, never operate the NetServer 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).
4. Disconnect the power cord from its power source.
5. To remove the bezel, pull the top of the bezel forward until it unsnaps, then lift the entire bezel
upward and away from the chassis.
The bezel connects to the front of the HP NetServer chassis with two snap-in connectors at the
top front of the chassis and two metal tabs, which fit into two slots on the bottom front of the
chassis.
