Twisted-Pair Connections
All models, excluding the R641-53, R641-55, R642-53 and R642-55,
provide one or two shielded RJ-45 connectors which support a maxi-
mum segment length of 100 meters. Use Category 3, 4 or 5 cables for
10Mbps segments; only use Category 5 cables for 100Mbps segments.
NOTE: Be sure to properly set the MDI-II to MDI-X
switch located
between the two port connectors. Refer back to
Step 2
if necessary.
Once power is applied to the line card, correct connectivity can be
verified via the LK (link) LED, if a device is connected to the remote
end of the cable.
