Replacing The I/O Board; Removing The I/O Board - Intel SR870BN4 - Server Platform - 0 MB RAM Product Manual

Replacing the I/O Board

The I/O board resides on the bottom of the I/O bay and plugs into the midplane board. The I/O
board accepts the I/O riser card, the DC-to-DC converters, and the PCI add-in cards.

Removing the I/O Board

1. Observe the safety and ESD precautions described in "Removing the I/O Board" on page 197.
2. Turn off all peripheral devices connected to the system.
3. Power down the system by pressing and holding the power button on the front panel for several
seconds. Unplug both AC power cords to remove standby power from the server.
4. Disconnect all peripheral cables attached to the I/O bay.
5. Slide the I/O bay out of the chassis and place on a clean static-free work surface.
6. Remove all PCI add-in boards from the I/O bay as described in "Removing the I/O Board" on
page 197.
7. Remove the I/O riser card as described in "Removing the I/O Riser Card" on page 187.
8. Remove the four DC-to-DC converters plugged into the I/O board as described in "Removing
I/O Board DC-to-DC Converters" on page 193.
9. Remove the fan housing as described in "Removing the Fan Housing" on page 195.
10. The PCI slot plastic dividers (A in Figure 72) can be removed by pulling them in the direction
of the arrow. Alternatively, they can be left in place and removed as an assembly (dividers and
plastic base) in step 13.
11. If the optional external SCSI connector is installed, loosen the captive screw (A in Figure 73),
remove the back panel SCSI connector (B in Figure 73) and drape the cable over the side of the
chassis out of the way (C in Figure 73).
