Chapter 3 Maintaining the Server
Installing or Replacing Server Components
Enabling or Disabling the Internal USB Port
Caution We do not recommend that you hot-swap the internal USB drive while the server is powered on.
The factory default is for all USB ports on the server to be enabled. However, the internal USB port can
be enabled or disabled in the server BIOS. See Figure 3-16 for the location of the USB port on the
motherboard.
Step 1 Enter the BIOS Setup Utility by pressing the F2 key when prompted during bootup.
Step 2 Navigate to the Advanced tab.
Step 3 On the Advanced tab, select USB Configuration.
Step 4 On the USB Configuration page, select USB Ports Configuration.
Step 5 Scroll to USB Port: Internal, press Enter, and then choose either Enabled or Disabled from the dialog
box.
Step 6 Press F10 to save and exit the utility.
Replacing a Cisco Modular RAID Controller Riser (Internal Riser 3)
The server has a dedicated internal riser (riser 3) that is only used for the Cisco modular RAID controller
card. This riser plugs into a dedicated motherboard socket and provides a horizontal socket for the Cisco
modular RAID controller card.
Step 1 Prepare the server for component installation:
a. Power off the server as described in Shutting Down and Powering Off the Server, 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, page 3-8.
Step 2 Remove the existing RAID controller riser (see Figure 3-17):
a. If the existing riser has a card in it, disconnect the SAS cable from the card.
b. Lift the riser straight up to disengage the riser from the motherboard socket. The riser bracket must
also lift off of two pegs that hold it to the inner chassis wall.
c. Set the riser upside down.
d. Remove the card from the riser. Loosen the single thumbscrew that secures the card to the riser
bracket and then pull the card straight out from its socket on the riser (see Figure 3-18).
Step 3 Install a new RAID controller riser:
a. Set the new riser upside down.
