Installation Guidelines
Installation Guidelines
Follow these guidelines when installing a PFC3B or PFC3BXL on a Supervisor Engine 720:
• If you have redundant Supervisor Engine 720s, the hardware on both supervisor engines must be
identical. You cannot have a mix of PFC3A, PFC3B, or PFC3BXL in the same chassis. You must
shut down the switch to install the PFC3B or PFC3BXL, even if you have redundant supervisor
engines.
• If you have redundant Supervisor Engine 720s, you must install the PFC3B or PFC3BXL on each
Supervisor Engine 720.
• Observe the following cautions:
Caution Always use an ESD wrist strap when handling modules or coming into contact with internal
components.
Caution Use care not to damage the connectors on the supervisor engine. If you damage a connector,
you will have to return the supervisor engine to Cisco for repair.
Caution Ensure that the PFC3B or PFC3BXL is securely seated before you install and tighten the cap
nut and the securing screws. If you use the screws to seat the PFC3B or PFC3BXL, the card
might warp.
Caution You must install all screws. The screws provide grounding between the PFC3B or PFC3BXL
and the supervisor engine. Failure to install all screws will invalidate the safety approvals and
can cause fire and electrical hazards.
Caution The hardware on both supervisor engines in a single chassis must be identical. If you have
redundant supervisor engines, you must install a PFC3B or PFC3BXL on each Supervisor
Engine 720.
