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.
WARNING! Hazardous voltages are present inside the server. Always remove AC power
from the server and associated assemblies while working inside the unit. Serious injury can
result if this warning is not observed.

• Electrically conductive field service kit (P/N 9300-1155)
• 1/4 inch flat blade screwdriver

Accessing a Rack Mounted Server
The HP Integrity rx4640 server is designed to be rack mounted. The following procedure explains
how to gain access to your server that is mounted in an approved rack. For rack installation
instructions, review the document titled Installation Guide, Mid-Weight Slide Kit, 5065-7291. This
document is on the HP website at: http://www.hp.com/racksolutions.
WARNING! Ensure that all anti-tip features (front and rear anti-tip feet installed; adequate
ballast properly placed; and so on) are employed prior to extending the server.
Extending the Server From the Rack
NOTE: Ensure that there is enough area (approximately 1.5 meters [4.5 ft]) to fully extend the
server out the front and work on it.
To extend the server from the rack, follow these steps:
1. Remove the T-25 screws that fasten the server to the rack. See Figure 4-1.
2. Flip out the two pull handles at either end of the front bezel and slowly pull the unit forward
by the handles. The server is fully extended when the rail clips are locked in place. When
fully extended, the front and top covers are fully accessible.
