Chapter 11 XSCF Unit Replacement 11-13
Caution – After stopping all the domains, be sure to switch off the main line switches in
the power supply system to completely shut off the supply of power.
6. Connect the clip of the antistatic wrist strap and of the antistatic mat to the server
grounding port. (See Section 1.4, “Antistatic Precautions” on page 1-9)
7. Ensure that the metallic underside of the wrist strap is in direct contact with your
skin.
The wrist strap should be snug around the wrist so that it does not rotate. (See Section 1.4,
“Antistatic Precautions” on page 1-9)
Caution – Before handling FRUs, be sure to connect the clip of the antistatic wrist strap
and of the antistatic mat to the server grounding port, and attach the band of the wrist strap
to one of your wrists. Place the FRUs on the grounded antistatic mat. Failure to take these
antistatic measures might result in serious damage.
8. For the M9000 (with the expansion cabinet), disconnect the cables from the
connectors of the XSCFU to be replaced. Disconnect any other cables, such as a LAN
cable, as necessary.
9. Remove the XSCFU to be replaced. (See
FIGURE 11-5 or FIGURE 11-6)
a. Using a Phillips screwdriver, turn the knob screws securing the upper and lower
eject/lock levers (in the M8000 server) or left and right eject/lock levers (in the
M9000 server) 90 to 180 degrees to unlock the levers. (Turn the knob screw while
lightly pulling the lever by one hand.)
b. Unlock the eject/lock levers to pull the XSCFU off the backplane.
c. While grasping the eject/lock levers, pull out the XSCFU slowly from the slot.
10. Place the removed XSCFU on an antistatic mat.
11. Mount the replacement XSCFU by following the removal instructions in Step 8 and
Step 9 in reverse order. Align the XSCFU with the slot guides, insert it carefully, and
secure it firmly.
Push the levers as far as they will go, and then push the knob screws on the eject/lock
levers to lock them in position. When the knob screws remain in position, the XSCF unit
is securely mounted.
Caution – Do not forcibly push the XSCFU when inserting it, even if it is not moving
smoothly. You may fail to insert the XSCFU due to the presence of any obstruction in a slot
or any problem with a connector pin; and if you forcibly insert it, serious damage may result.
