Installing PCI retainer

1. Disconnect power from the system (

Predisassembly procedures on page 57) and remove the side

access panel (

Side access panel on page 63).

2. Attach the PCI retainer. For short PCI cards, attach the hooks of the support arm 1 under the slots

on the rear of the chassis, and rotate the card support down. The arm will flex on the card and you

lift the front part of the arm 2 onto the chassis.

●

For short PCI cards, attach the lip of the PCI retainer over the chassis slot 1 and pull the lower

part of the arm over the PCI retention clamp 2.

●

For tall PCI cards, attach the lip of the PCI retainer under the chassis slot 1 and pull the lower

part of the arm over the PCI retention clamp 2.

Express lane consists of four wires and can transmit 250 MB in a single direction or 500 MB in both

directions simultaneously. This bandwidth is not affected by what is happening on other PCI Express
