Installing Components When the Server is in a Rack
Power supplies, disks and fans can be installed when the server is fully inserted into a rack. Only front and
rear access is required.
Internal components can be accessed by removing the top cover. Proceed as follows:
WARNING Hazardous energy is present inside the HP Server. Always remove power from the
server before working inside the unit. Serious injury may result if this warning is
not observed.
NOTE Ensure that there is enough area (approximately 1.5 meters [5 ft.]) to fully extend the server
out the front of the rack and work on it.
Step 1. Turn off and disconnect system power. Disconnect power at the DC source end of the power cable(s),
using the disconnect device that is part of the rack or facility power system.
Step 2. Label and disconnect all cables from the unit rear panel connectors.
Step 3. Remove or loosen (as appropriate) the screws that fasten the server to the rack.
Step 4. If the server is slide-mounted, slowly pull the chassis forward (or push from the rear) to extend the
chassis from the rack. The server is fully extended when the rail clips are locked in place. If the
server is tray-mounted, it is not held in the rack and can fall from its mounting. Do not extend the
server from the rack but remove it from the rack for internal access.
Step 5. Remove the top cover. Refer to “Removing the Top Cover” on page 25.
Remove the Server from a Rack
WARNING Do not attempt to lift the server alone. The server may weigh as much as 32
kilograms (70 lbs). Serious injury may result if this warning is not observed.
NOTE Ensure that there is enough area (approximately 1.5 meters [5 ft.]) to fully extend the server
out the front of the rack and work on it.
To remove the server from the rack, perform the following steps:
Step 1. Turn off and disconnect system power. Disconnect power at the DC source end of the power cable(s),
using the disconnect device that is part of the rack or facility power system.
Step 2. Label and disconnect all cables from the unit rear panel connectors.
Step 3. Remove or loosen (as appropriate) the screws that fasten the server to the rack.
Step 4. Label and disconnect the rack/facility ground cable from the chassis rear panel. (See Figure 3-1.)
