Automatic Cable Sensing on Twisted-Pair Ports:
When the ports for the 10/100-TX and the Gig-T vl Modules are in their default
configuration,
Auto
, both modules automatically negotiate whether the ports
operate as MDI or MDI-X, depending on the cable type and the connected
device’s operation. As a result, you can use either straight-through or
crossover twisted-pair cables for all network connections to these modules.
On the 10/100-TX vl Modules, this feature is identified as
HP Auto MDI-X
; on
the Gig-T vl Module, it is identified as
IEEE Auto MDI/MDI-X
and it is part
of the IEEE 802.3ab standard. Both features operate the same.
Operation of this feature depends on the port configurations being kept at
Auto
. If the configuration is changed to one of the available fixed options (for
example, 100-Full Duplex), the port operates as an MDI-X port. In that case,
to connect the module to another switch or hub, use a crossover cable; to
connect to an end node, use a straight-through cable.
