HP DC SAN Backbone Director Switch Hardware Reference Guide (5697-2158, August 2012)

Removing a control processor blade (CP8)
The DC SAN Director continues to operate while a CP blade is being replaced if the redundant
CP blade is active and a failover does not occur. You can prevent failover by entering the
haDisable command.
CAUTION: Wear a grounded ESD strap when handling DC SAN Director components. The
Director chassis provides a grounding connection above the power connectors. Also, store
ESD-sensitive components in antistatic packaging.
IMPORTANT: The CP8 blade is compatible with the DC SAN Director and the DC04 SAN
Director.
To remove a CP blade:
1. Remove the chassis door. See Removing the chassis door (page 62).
2. Log in to the active CP as the admin user. You can use a serial cable or Telnet, Web Tools,
or Fabric Manger. Determine which CP is active using the haShow command or view the
active LED on the front of the CP.
3. If the faulty CP is the active CP, issue the haFailover command. Wait until the failover has
completed. Use the haShow command to verify that the CPs are synchronized and the failover
is complete.
4. Power off the blade by sliding the slider switch in the top ejector down to the off position (see
Figure 36 (page 70)).
5. Disconnect all cables from the faulty (standby) CP.
6. Use the Phillips screwdriver to unscrew the thumb screw from both ejectors.
7. Open both ejector handles simultaneously to approximately 45 degrees and remove the CP
blade from the chassis (see Figure 36 (page 70)).
