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
“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. Remove the XBU to be replaced. (See
)
a. If the M9000 server expansion cabinet is installed, firstly make room for drawing
the crossbar unit. Move the cable support brackets at the front of the replacement
target crossbar unit up or down by one tier (by a single hole) with the cables
attached. In so doing, move the cable support brackets above the target crossbar
unit up and move the brackets under the target crossbar unit down, for one layer
each.
b. Secondly, remove the clock cables connecting the crossbar units in the base and
the expansion cabinets, and then use a flathead screwdriver to remove the data
cables.
c. Using a Phillips screwdriver, turn the knob screws securing the left and right
eject/lock levers 90 to 180 degrees to unlock the levers. (Turn the knob screw
while lightly pulling the lever by one hand.)
d. Unlock the eject/lock levers to pull the XBU off the backplane.
