Cold swap procedure. Use this procedure to replace CP blades after removing
power to the device.
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 133.
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.
