Replacing a Mezzanine Card

The server has a dedicated socket on the motherboard for a mezzanine-style RAID controller card.

Note See RAID Controller Considerations, page C-1for more information about supported cards and cabling.

To install or replace a mezzanine card, follow these steps:

Step 1 Remove the mezzanine card that you are replacing (see Figure 3-19):

a.Power off the server as described in the “Shutting Down and Powering Off the Server” section on page 3-7.

b.Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution If you cannot safely view and access the component, remove the server from the rack.

c.Remove the top cover as described in “Removing and Replacing the Server Top Cover” section on page 3-8.

d.Disconnect all cables from the mezzanine card.

Tip Label the cables before you disconnect them to aid replacement.
