You can installFPCs in any order, however.
Be sure there isa blank panelover every empty slot. The blank panels must be in
place during router operation to guarantee ad equate circulation of cooling air.
To reinstallthe FPCs, follow this procedure (seeFigure 46):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wris t and
connect the strap toone of the ESD points on the chassis. Make sure the router
is attached to a proper earth ground. For more information about ESD, see
“Preventing ElectrostaticDischarge Damage” on page 226.
2. Locate the leftmost slot in the FPC card cage on the front of the chassis. It is
directly below the offline button on the craft interface that is labeled FPC0.
Locate the FPC that you labeled FPC0 during removal.
3. Verify that the ends of the ejector levers, which are located at each end of the
FPC, are pushed outward,nearly perpendicular to the face of the FPC.
