Common Procedures
This section provides information on how to remove and replace server components for the upgrades
described in this guide.
Safety Information
This section describes gaining access, removing, and installing components in your HP 9000 rp3410 and
HP 9000 rp3440 server. Always disconnect power to prevent injury. Always take the appropriate measures to
prevent equipment damage by electrostatic discharge.
Disconnect power from external server connectors before you upgrade the server. Voltages are present within
the server whenever power is connected, even when the power switch is set to OFF.
WARNING Ensure that the system is powered down and all power sources have been
disconnected from the server prior to working with the server.
Voltages are present at various locations within the server whenever an AC power
source is connected. This voltage is present even when the main power switch is in
the off position.
Failure to observe this warning could result in personal injury or damage to
equipment.
Many server components are electrostatic discharge (ESD) sensitive. Use care to prevent equipment damage.
Observe the following practices:
• Use an antistatic wrist strap and a grounding mat, such as those included in the Electrically Conductive
Field Service Grounding Kit (HP 9300-1155)
• Handle accessory boards and components by the edges only. Do not touch any metal-edge connectors or
any electrical components on accessory boards
• Do not wear clothing subject to static charge build-up, such as wool or synthetic materials
Removing and Replacing the System Covers
The HP 9000 rp3410 and HP 9000 rp3440 servers are designed to be tower or rack mounted. This section
explains how to remove and replace the cover for both tower and rack mount configurations.
WARNING Do not remove the system cover without first turning the system off and unplugging
the power cord from the outlet or power protection device unless you are only
replacing a hot-swappable fan. Always replace the cover before turning the system
on.
