Removing Covers - Pedestal (LC 2000) Use this procedure to remove the bezel and covers (left & right) on the pedestal version of the HP NetServer LC 2000. • 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. 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. 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). 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. 28
