Control processor blade (CP8) removal and replacement
5
bring both blades to the same firmware version. Once you have installed the replacement CP
blade, see
“Verifying operation of the new CP blade” for information about determining the
version of firmware on the replacement CP blade and upgrading it if necessary.
For this procedure, please refer to “ESD precautions” and Figure 22 .
Complete the following steps to remove a CP8 control blade (CP).
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 your left.
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.
3. Tighten the thumb screw inside each handle using the Phillips screwdriver.
4. Turn the CP blade on 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 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. Remain logged in to the active CP and continue to “Verifying operation of the new CP blade.”
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, perform the following steps.
1. Type slotShow. The command output shows the new CP blade as “enabled.”
If the standby CP is unresponsive, you can try unplugging the new CP blade, running haDisable
on the active CP blade, and plugging the new CP blade back in. At that point, you can repeat
step 1 above to begin the verification process again.
2. Determine the version by entering firmwareShow. If the serial console on the replacement CP
blade is connected, issue the firmwareShow command there. More information is available
through the console.
NOTE
The DCX 8510-4 requires Fabric OS 7.0.0 or later to be recognized. If the firmware on the
replacement blade is earlier than 7.0.0 it must be brought up to the version on the active CP
blade, which must be at least 7.0.0.
3. If the firmware versions for both CP blades are the same, skip to “Complete the replacement.”
If the firmware version on the replacement blade does not match that on the active CP blade, a
warning message appears with the results of the firmwareshow command. The results of the
firmwareshow command may look similar to the following. Note the warning message at the
end of the output.
