5 RRP: Control processor blade (CP8) 4. If the functioning CP blade is performing as the active CP blade, go to step 5. If the faulty CP blade is performing as the active CP blade, fail over the blades: a. Log in to the faulty CP blade as admin, using either a Telnet or a serial console connection. If you connect successfully to the faulty CP, continue to step b. If you cannot connect to the faulty CP, remove the faulty CP blade for repair as follows: • Turn the CP blade off and notify the PowerConnect B-DCX-4S of a hot swap request by sliding the slider switch in the left ejector to the off position (Figure 23). • Wait until the active CP LED on the functioning CP blade is lit. Remove the CP blade. b. Enter haFailover. The functioning CP blade becomes the active CP blade. c. Wait until the status LED on the functioning CP blade is no longer lit. d. Enter haShow from the functioning CP blade (the new active CP blade) to verify the failover.
