Chapter 6 Maintaining the Router
Removing and Installing a Clock and Scheduler Card, Switch Fabric Card, or Alarm Card
Caution When operating your router with a single CSC, the second CSC slot must have a
CSC blank filler (MAS-GSR6-CSCBLNK=) installed to ensure electromagnetic
compatibility (EMC) compliance, to avoid overheating, and to ensure compliance
with regulatory electromagnetic interference (EMI) standards.
Step 6 Slide the card out of the slot and place it directly into an antistatic bag or other
ESD-preventive container.
If you plan to return the defective CSC to the factory, repackage it in the shipping
container you received with the replacement card.
Installing a Clock and Scheduler Card
To install a clock and scheduler card, see Figure 6-32 and follow these steps:
Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis
or to another grounded, bare metal surface.
Step 2 Remove the CSC from its antistatic bag or ESD-preventive container.
Caution Avoid touching the card circuitry or any connectors.
Step 3 Touching only the metal card carrier, use your free hand to support the bottom of
the CSC.
Caution CSC slots are equipped with card alignment grooves on both sides. When you
insert a CSC in the slot, make sure you carefully align both edges of the card
carrier in the corresponding card slot grooves.
Step 4 Set both edges of the CSC carrier into the card slot carrier alignment grooves on
either side of the CSC slot.
Step 5 Pivot the ejector levers away from each other; rotate each ejector lever outward
away from the faceplate.
