When a port labeled with an “X” is connected to a device that
does not support the crossover function, straight-through
cabling can be used. However, when connecting two identical
ports (that is, ports that either both support or do not support
the crossover function), the crossover must be implemented in
the wiring. This is summarized in the following table:
A list of the fixed and switch-selectable crossover (uplink) ports
for each TigerStack model can be found in the following table:
Connecting Devices
Adapters, other hubs, and LAN switches are connected to
10BASE-T ports of a TigerStack hub with a twisted-pair cable
segment. If the hub is located in a wiring closet, the connec-
tion to an adapter is made via a patch cable, modular wall out-
let, punch-down block, and patch panel.
