Removing the Integrated Storage Controller Card
WARNING:
Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Before you begin this
procedure, review the safety instructions that came with the system.
1 Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet.
2 Open the system. See "Opening the System."
3 Remove all expansion cards from expansion-card riser 1. See "Removing an
Expansion Card."
4 Disconnect the SAS cable(s) from the storage controller card.
CAUTION:
Disconnecting the RAID battery cable from a PERC card can cause
data loss if the "dirty cache" LED on the card is lit. The LED indicates that data is
still cached in controller memory and the data was not cleared at system
shutdown.
5 If necessary, disconnect the RAID battery cable from the controller.
6 Bend both card-edge guides outward and pull the storage controller card
out of the connector. See Figure 3-20.
7 Bend outward on both card-edge guides to release the controller, lift the
side of the controller that is adjacent to the blue guide, and then remove
the controller out towards the rear of the chassis. See Figure 3-20.
Installing the Integrated Storage Controller Card
1 With the storage controller card-edge facing the riser, insert one side of the
card into the black card-edge guide.
2 Bend outward on the blue card-edge guide, lower the card onto the blue
card-edge guide, and release the guide. See Figure 3-20.
