Removing Hardware
Note
4
The following steps explain how to remove a 10Base-T hub and associated
hardware from a Catalyst test system.
1) Remove the external network cable (pn 804-183-00) connecting the
second optional ethernet board in the user computer to the external
network.
Discard the existing 804-183-00 cable and install the replacement 804-183-00
included in the upgrade kit. The existing cable will not support 100Base-T
operation.
2) Remove the center test system cover by releasing the two quarter-turn
fasteners in the middle of the cover (service side). Then lift the cover away
from the mainframe.
3) Remove the test system cover on the left side of the service side by
releasing the quarter-turn fastener at the lower left side of the cover. Then
lift the cover away from the mainframe.
4) Detach the AD958 user power panel mounted in front of the option space
by loosening the two screws holding the power panel to the mainframe.
The upper screw is captive and the lower is conventional. See [A] and [B]
in
AD958
Detail.
Carefully pull the power panel away from the option space and tie-wrap
the AD958 and cables to the mainframe to reduce strain.
