Chapter 10 Switch Maintenance Procedures
Replacing Cards
Automatic Response for Redundant PXM Installations
For redundant PXM installations, the nativity check is performed only on the active PXM card set. If an
active PXM card set is operating correctly, you can replace any card in the standby or non-active card
set, and the active card set will attempt to configure the replacement card and bring it up in standby
mode.
When the entire switch is reset, the nativity check is used to determine which card set gains mastership.
The card set that gains mastership will attempt to go active and will resolve nativity conflicts as
described in
Table 10-1 . Table 10-2 shows how the nativity check is used to assign mastership to a PXM
card set.
PXM front card and hard
disk card are replaced
with a set that was
configured in another
switch. PXM45 Non-native front card and
non-native hard disk card. The standalone PXM enters the failed state.
You must manually resolve the
configuration conflict as described in the
“
Manually Responding to Nativity Checks ”
section which appears later in this chapter.
Both PXM front card and
hard disk card are
replaced with cards that
were configured in
different switches. PXM45 Non-native front card and
non-native hard disk card. In this scenario, you can clear the
configuration stored on the PXM cards,
restore a configuration from a saved file, or
you can use the configuration stored on the
hard disk. You must manually resolve the
configuration conflict as described in
“
Manually Responding to Nativity
Checks ,” which appears later in this
chapter.
