Basic procedures
4.5 Opening the server
VCAUTION!
●Only for non-hot plug components:
Before removing or installing covers, turn off the server, all peripheral
devices, and any other connected devices. Also unplug all power
cables from the outlet. Failure to do so can cause electric shock.
●The housing covers must be replaced as soon as possible for
purposes of cooling, to comply with EMC regulations (regulations
regarding electromagnetic compatibility) and to prevent fires. The
housing covers must not remain open for longer than 5 minutes.
●Follow the safety instructions in the chapter "Safety instructions" on
page 31.
The server is accessible via three covers, see figure5, that can be removed
independently from each other:
1. Front cover, see "Removing the front cover" on page45
2. Fan cover, see "Opening the fan cover" on page102
3. Rear cover, see "Removing the rear cover" on page46
You can remove the fan cover as such for accessing the fans directly. For all
other tasks, it is removed together with the front cover.
