Cold-Swap Procedure - IBM SAN512B-6 Installation, Service And User Manual

10. Log out of the standby CP blade and log in to the active CP blade.
11. Proceed to the procedures to "Completing the replacement."

Cold-swap procedure

Use this procedure to replace both CP blades while the device power is off. You
must power off the device to replace both CP blades. To replace a single blade,
refer to the hots-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.
