Replacement Procedure

6 Control Processor Blade (CP8) Replacement Procedure
53-1001806-01
Removing a control processor blade (CP8)
The PowerConnect B-DCX 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.
ATTENTION
The instructions below refer to the top and bottom of each blade in the vertical orientation as used in the
PowerConnect B-DCX. For the PowerConnect B-DCX-4S, because the blades are horizontally oriented, top should be
read as left and bottom should be read as right.
ATTENTION
Follow ESD precautions (see “ESD Precautions” in your chassis’ hardware reference manual).
NOTE
The CP8 blade is compatible only with the PowerConnect B-DCX-4S Backbone and the PowerConnect B-DCX
Backbone.
1. Remove the chassis door (see the Chassis Door Replacement Procedure for your chassis).
2. Power off the faulty blade by sliding the slider switch in the top ejector down to the off position (Figure 1).
3. Disconnect all cables from the faulty (standby) CP.
4. Unscrew the thumb screw from both ejectors using the Phillips screwdriver.
5. Lever open both ejector handles simultaneously to approximately 45 degrees and pull the CP blade out of the
chassis (Figure 1 and Figure 2).
