Removing a CP
Remove a CP from a Passport switch to replace it or upgrade it.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• When upgrading (or downgrading) CP2 and CP3 card pairs, ensure that
you have followed the criteria identified in 241-5701-600 Passport 7400,
15000, 20000 Configuration Guide.
Procedure steps
1 At the front of the Passport 15000 or 20000, locate the CP to be removed.
The slot numbers are labeled on the shelf below the cards.
2 To ensure that proper connection of cables at the faceplate, verify that
each cable has a label matching the faceplate receptacle label or that its
connector is a unique size and shape for that its receptacle. If a label is
missing, add it.
3 Wait in readiness until the software operator confirms that the CP is
offline, that is, out of service and ready to be replaced. The CP LED
indicates solid red for only a few seconds. While the LED is solid red,
unseat the CP by fully swinging out the upper and lower card latches until
they stop horizontally, then pull the card at the faceplate to remove it about
10 cm (4 in.).
After a few seconds of being offline, the CP is automatically reloaded. The
LED changes from solid red to flashing red to indicate loading has begun.
If reloading begins, do not remove the CP. You must wait until loading
completes. Otherwise, traffic on other hardware parts such as a fabric or
an active CP can be degraded or dropped by the subsequent steps.
CAUTION
Risk of shelf reset by disconnecting an active cable
If the Ethernet cable is disconnected from the active CP,
the shelf undergoes a switchover to the spare provided the
mate is in-service. The status LED of an active CP is solid
green. Only one CP can be active.
