Replacing the PCI OLR Assembly
To replace a PCI OLR assembly, follow these steps:
1. Position the assembly at an angle so that the bottom holding tabs engage into the bottom
holes of the chassis.
2. Tilt the assembly toward the chassis, bringing it upright, and engage the plastic tabs so that
the assembly is firmly and evenly attached to the chassis.
3. Replace all the PCI MRLs one at a time, beginning at the right-most clip position. Ensure
that the PCI MRL is in the OPEN position before inserting the bottom pivot pin into the hole
in the chassis.
4. Press the PCI MRL axle into the retaining clip.
5. Flip all the PCI MRLs to the CLOSED position.
6. Reconnect the PCI OLR cable to the PCI OLR assembly. Be sure that the connector is inserted
with the correct polarity orientation.
7. Replace the PCI access panel.
