Hot-Plug Procedures
The hot-plug procedures described in this section use the hardware interface only. Software interface
procedures are described in Table 3-10 on page 100.
IMPORTANT Before adding or replacing a PCI/PCI-X card, determine whether that card is critical to the
server operation. If you replace a card that is still operating and it is a critical resource to the
server, you can cause undesired system downtime.
OLA
Before installing a PCI/PCI-X card, ensure that the proper drivers for that PCI/PCI-X card are installed.
NOTE If you are installing the Graphics Kit A6150B, use slots 3-8. However, DO NOT install the
included USB card. The server currently supports USB and the ports are already located on the
rear of the server.
If you are installing the RAID card A7143A, you must install it into slot 8. If you install this
card in any other slot, it interferes with the manual retention latch (MRL) on the OLX divider
in the next slot. Because of this interference, you can install only two RAID cards in the server
in slot 1 and slot 8.
To add a PCI/PCI-X card into an empty slot, follow these steps:
Step 1. If rack-mounted, slide the server out from the rack until it stops. (See “Extend the Server from the
Rack” on page 64.)
Step 2. Remove the top cover from the chassis. (See “Removing the Top Cover” on page 73.)
Step 3. Choose an empty slot and pull up on the MRL located on the OLX divider approximately 75
degrees. (Figure 3-33)
CAUTION Do not pull up on the MRL of a powered on, occupied slot or the server will crash.
