About the CP Card
High availability is provided through redundant CP cards. One CP card acts as the
active CP card, actively controlling the Core Switch 2/64. The other acts as
standby in case rapid failover is required. Failover occurs as soon as the active CP
card is detected to be faulty or uninstalled. If the active CP card fails or is
uninstalled, the standby CP card automatically becomes the new active CP card.
The configuration is mirrored to the standby CP, so that if failover occurs, the
current configuration is still available.
Information about both CP cards, including which card is active, is available
through the hashow command. For information about commands and whether
they can be entered through the active or standby CP card, refer to the HP
StorageWorks Fabric OS Version 3.1.x/4.1.x Reference Guide.
The switch can continue to operate while a CP card is being replaced. To ensure
correct air circulation inside the switch and protection from dust, filler panels can
be ordered for any empty slots. An illustration of the CP Card is provided in

Caution:
Wear a grounded ESD strap when handling a CP card. A
grounding connection is available on the chassis above the power
connectors.
To ensure correct cooling of the chassis and provide protection from dust,
install a filler panel in any slots that do not contain a CP card.
Disassembling any part of a CP card voids the part warranty and regulatory
certifications. There are no user-serviceable parts inside the CP card.
