Moving ServerNet Cables to Different Ports on the
ServerNet II Switches
Moving ServerNet Cables to Different Ports on
the ServerNet II Switches
The ServerNet II Switch is the main component of the cluster switch. Figure 6-1 shows
the ServerNet II Switch extended for servicing.
If a PIC installed in a ServerNet II Switch is faulty, you might need to move the fiber-
optic cables providing the external X-fabric and Y-fabric connections to different
(unused) ports on the X and Y ServerNet II Switches. (Because the cables must use
the same port on ServerNet II Switches, you must move both cables.)
You can move the cables to unused ports on the same group of switches. For
example, if the cables are currently connected to port 4 of the X1 and Y1 ServerNet II
Switches, you might move them to port 7 of the X1 and Y1 ServerNet II Switches.
Or you can move the cables to unused ports on the other group of switches. For
example, you might move the cables in the previous example to port 6 of the X2 and
Y2 ServerNet II Switches. However, make sure that both cables connect to the same
group of switches (X1 and Y1 or X2 and Y2—but not X1 and Y2).

Note. This procedure moves the cable connections at the ServerNet II Switches only. At the
server, the fiber-optic cables must always connect to port 6 of the MSEBs in slots 51 and 52 of
the group 01 enclosure.
