Removing a CP card
The 4/256 SAN Director continues to operate while a CP card is being replaced if the redundant
CP card is active and a failover does not occur (you can prevent failover by issuing the haDisable
command).
CAUTION: The core section within the 4/256 SAN Director CP cards provides internal routing
bandwidth that is always active on both CP cards. Removing a CP card might impact user
performance and should not occur until the replacement CP card is ready to be installed.
WARNING! Do not replace the real time clock battery on a CP card. There is danger of explosion
if the battery is incorrectly replaced or discarded. Contact HP Technical Support if the real time
clock begins to lose time.
To remove a CP card:
1. Login to the active CP as admin.
2. You can use a serial cable or if you have connected the Director to your IP network, you can use
telnet, Web Tools, or Fabric Manger. You can determine which CP is active using the haShow
command or view the active LED on the front of the CP.
3. If the CP you want to replace is the active CP issue the haFailover command. Wait until the
failover has completed. Use the haShow command to verify the CPs are synchronized and the
failover is complete.
4. Use the slider to power off the blade, and wait until the standby CP power LED is off.
5. Disconnect all cables (modem, serial, Ethernet) from the standby CP.
6. Unscrew the thumb screw from both ejectors using the Phillips screw driver.
7. Lever open both ejector handles simultaneously to approximately 45 degrees and pull the CP
card out of the chassis (see Figure 31 on page 115).
