HP DC04 SAN Director Switch Hardware Reference Guide
To remove a CP blade:
1. Remove the chassis door. See Removing the chassis door (page 65).
2. Log in to the active CP as admin. 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 38 (page 73)).
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 38 (page 73)).

Installing a control processor blade (CP8)
CAUTION: Wear a grounded ESD strap when handling a CP8 blade. Use the grounding
connections above the power connectors on the chassis.
To install a CP blade (slot 4 or 5):
1. Open the ejector handles to approximately 45 degrees. Orient the CP blade so that the
handles are toward you and the flat metal side is on the bottom.
2. Align the flat metal side of the CP blade inside the left and right blade guides in the slot. Slide
the CP blade into the slot until it is firmly seated (see Figure 38 (page 73)).
3. Use the Phillips screwdriver to tighten the thumb screw inside each handle.
4. Power on the CP blade by sliding the ON/OFF switch in the left handle to the left, to cover
the thumb screw.
5. Verify that the power LED is green. If it is not, ensure that the CP blade has power and is firmly
seated and that the ejectors are in the locked position.
6. Connect the cables to the new CP blade.
7. Verify the installation. See Verifying operation of the new CP blade (page 73).
8. Replace the chassis door. See Installing the chassis door (page 65).
Verifying operation of the new CP blade
To verify that boot and POST are complete on the new CP blade and that the CP blade has achieved
failover redundancy:
1. Log in to the active CP as admin.
2. Enable the redundancy feature using the haEnable command.
