Connecting the Four-Lane Links
Connecting the Four-Lane Links
When the guided procedure indicates that both clusters are ready to add remote
cluster switches, you can connect the four-lane links between the X1/Y1 and X2/Y2
cluster switches.
To connect the four-lane links:
1. Label both ends of each fiber-optic cable to be used for the four-lane links. On the
label, include the fabric and cluster switch position (X1, for example) and the port
number (8, for example) to which the cable will be connected.
2. If they are not already routed, route the fiber-optic ServerNet cables to be used for
the four-lane links.
3. Remove the black plugs from ports 8 through 11 on the double-wide PICs inside
each switch enclosure.
4. Remove the dust caps from the fiber-optic cable connectors.
Caution. Before connecting ServerNet cables, inspect the cables as described in Connecting
a Fiber-Optic Cable to an MSEB or ServerNet II Switch on page 3-18. Using defective
connectors can cause ServerNet connectivity problems.
Note. ServerNet II Switch ports 8, 9, 10, and 11 are keyed differently from ports 0 through
7. To connect the four-lane link cables, you must align the fiber-optic cable connector with
the key on top. See Figure 4-8
.
