Recording critical backbone information
Back up the backbone configuration before you replace a CP blade. Refer to the Fabric OS Administrator’s Guide for
backup information.
ATTENTION
The instructions below reference specific slot numbers. these numbers will be different between the PowerConnect
B-DCX-4S and PowerConnect B-DCX.
1. Log in to the functioning CP blade as admin, using the serial console connection.
2. Type haShow to determine which CP blade is active:
swDir:admin> haShow
Local CP (Slot 7, CP1) : Active
Remote CP (Slot 6, CP0) : Standby, Healthy
HA Enabled, Heartbeat Up, HA State Synchronized
3. If the functioning CP blade is performing as the active CP blade, go to step 4. If the faulty CP blade is performing
as the active CP blade, fail over the blades:
a. Log in to the faulty CP blade as admin, using a serial console connection.
If you connect successfully to the faulty CP, continue to step b.
If you cannot connect to the faulty CP, remove the faulty CP blade for repair as follows:
• Turn the CP blade off and notify the backbone of a hot swap request by sliding the slider switch in the
top ejector down to the off position (Figure 1).
• Wait until the active CP LED on the functioning CP blade is lit. Remove the faulty CP blade.
b. Type haFailover. The functioning CP blade becomes the active CP blade.
c. Wait until the status LED on the functioning CP blade is no longer lit.
d. Type haShow from the functioning CP blade (the new active CP blade) to verify the failover.
Depending on the failure mode of the faulty CP blade, the haShow output may not show the “HA State
Synchronized” message but may indicate that the system is in non-redundant mode.
