Replacing A Cp Card - Brocade Communications Systems SilkWorm 12000 Hardware Reference Manual

Replacing a CP Card

This document describes how to remove and replace a Control Processor (CP) card from the SilkWorm
12000 switch (see
5 and the other in slot 6.
Both logical switches in the SilkWorm 12000 can continue to operate while a CP card is replaced if the
other CP card continues to operate and no failover occurs (you can prevent failover by entering the
hadisable command). The active CP card is determined by the most recent failover.
If you need to replace the active CP card and you are an earlier version of Fabric OS (prior to v4.1),
traffic through the SilkWorm 12000 may be temporarily suspended until failover to the standby CP card
is complete (a few seconds).
The configuration on the active CP card is automatically mirrored to the standby CP card; this section
includes steps to ensure that the new CP card boots up as the standby CP card.
The new CP card automatically assumes the IP address and host name assigned to the slot.
If the new CP card does not have the same firmware as the active CP card, it must be upgraded/
downgraded to the same firmware version.

SilkWorm 12000 Hardware Reference Manual
Figure 3-4 on page 3-14). Each SilkWorm 12000 has two CP cards: one located in slot
Disassembling any part of a CP card voids the part warranty and regulatory certifications.
There are no user-serviceable parts inside a CP card. To ensure adequate system pressure for
cooling purposes, leave the faulty CP card in the slot until you are ready to perform the
replacement procedure.
Use the same version of Fabric OS on both CP cards and logical switches. Using different
versions may cause malfunctioning. If the replacement CP card has a different version of
Fabric OS, bring both cards to the same firmware version.
Do not attempt to replace the battery on a CP card. There is danger of explosion if the battery
is incorrectly replaced or discarded. Contact the switch supplier if the real time clock begins
to lose time.
