Hot-swap procedure
Use this procedure to replace CP blades, one at a time, while the device power is on. The device
continues to operate while replacing a blade if the redundant blade is active and failover does not occur.
You can prevent failover by entering the
haDisable command.
To replace both CP blades with power off, refer to the cold-swap replacement procedures.
Removing a blade
Use the following procedure to power down the device and remove CP blades. You can replace a single
CP blade or both blades one at a time using the hot-swap procedure.
Procedure
1. Be sure to perform all steps under “Preparing for replacement” on page 138.
2. Power down the device.
3.
Remove the chassis door.
4. Disconnect all cables from the CP blades.
5. Loosen the captive screws for each ejector handle on the blade using a #1 Phillips screwdriver.
Loosening the screws initiates a hot-swap request and disconnects power from the blade. The
spring-loaded captive screws will pop out from the slot .63 cm (.25 in.) when fully disengaged. Do not
eject the blade using blade handles until screws disengage from slot and the power LED is off.
6. Grasp each ejector handle on blade and simultaneously pull the handles away from the blade to
approximately 45 degrees. As you move the handles, you will hear connectors disengaging from the
backplane connector and possibly a slight popping noise. This is normal and is due to the dense
backplane. The blade will move out approximately 1.27 cm (.5 in.) from the slot when fully
disengaged.
7. Slowly pull the blade from the slot. Do not support blade fully using injector handles after removal.
As you slide out the blade, place one hand under blade for support. Be sure blade has cooled
sufficiently to touch.
CAUTION:
To avoid damaging blade and chassis, do not push the blade into a slot or pull the blade from a
slot using the ejector handles.
