Removing the power supplies from the chassis
The two power supplies must be removed from the chassis; they will be installed
in the new chassis. Refer to Figure 21 on page 40 and Figure 22 on page 41 to
complete these steps to remove each power supply.
1. Push the locking tab to the left and hold it there while using the handle on the
power supply to pull it straight out and away from the chassis. Pull the power
supply out slowly to avoid catching a finger on the locking tab.
2. Set the power supply aside for later installation in the new chassis.
3. Repeat steps 1 and 2 for the other power supply.
Removing the fans from the chassis
The three fans must be removed from the chassis; they will be installed in the new
chassis. Refer to Figure 23 on page 42 and Figure 24 on page 43 to complete these
steps to remove each fan.
1. Using the Phillips screwdriver, unscrew the captive screw on the fan.
2. Remove the fan from the chassis by using the handle on the fan to pull it
straight out and away from the chassis.
3. Set the fan aside for later installation in the new chassis.
4. Repeat steps 1–3 for the other two fans.
Remove the old switch chassis and install the new switch
chassis
Follow these steps to remove the switch chassis from the cabinet. The rack mount
hardware from the old chassis will be used for installing the new chassis in the
cabinet. Depending on whether the switch chassis is mounted flush with the front
of the cabinet or flush with the rear of the cabinet, refer to "Installation instructions
for flush-front mounting" on page 12 or "Installation procedure for flush-rear
(recessed) mounting" on page 16 to complete the removal and installation of the
new chassis. Complete the appropriate instructions in reverse to remove the chassis
from the cabinet and the rack mounting kit hardware from the old chassis. Then
complete the appropriate instructions from the beginning to attach the rack
mounting kit hardware to the new chassis and install it into the cabinet.
You can install the power supply FRUs and fan FRUs into the new chassis either
before or after mounting the chassis in the rack. See "Fan removal and
replacement" on page 41 and "Power supply removal and replacement" on page
39 for details.
Complete these steps after the new chassis is installed in the cabinet.
1. Reconnect all transceivers and fiber cables, using the information recorded in
Table 24 on page 59 to ensure that connections are made to the correct ports.
2. Connect the two power cables to the power supplies and the power sources.
The switch will begin to power up and start the POST as soon as the first
power cable is connected.
3. Once POST has completed, the switch is ready to restore the saved
configurations. Refer to the Fabric OS Command Reference for more information
on the CLI commands.
