Replacement of NetBAY 2x8 console switch
To replace the console switch you must remove the rails from the cabinet.
Uncable the console switch
1. Turn power off to the console switch being replaced and remove the power
cord.
2. Note the connection positions of signal cables and then disconnect them.
Remove the rails from the cabinet
1.
Remove the mounting screws from the front vertical cabinet rails and remove
the cover brackets.
2.
Remove the mounting screws from the rear vertical cabinet rails.
3.
Slide the rails out the rear of the cabinet.
Remove the console switch from the rails
Unscrew the console switch from the rails. There are two holes on each side of the
device.
Install the console switch and rails into the cabinet
To install a replacement console switch proceed as follows:
1. Select the location of an added console switch according to the following rules:
v
If a second 1-GB Ethernet Switch is present, or if console switch cable length
restrictions require it, install the second console switch in slot 20 of an
Expansion cabinet. Nodes to be connected to a console switch cannot have
more than one cabinet intervening between their own cabinet and the one
where that console switch resides.
v
If a Myrinet switch is present and console switch cable length restrictions
allow it, install the second console switch in slot 21 of the Primary cabinet.
v
If no Myrinet switch is present and console switch cable length restrictions
allow it, install the second console switch in slot 16 of the Primary cabinet.
2. Mount the switch rails to the console switch.
a. Mount the rails so that the Cable Management Tab is on the left rail, and
the holes in the console switch align with the two smallest holes on each
rail, as shown in Figure 10 on page 82.
b.
Use two screws on each side to secure the device.
