Connecting To Ethernet Or Fast Ethernet Hubs - Brocade Communications Systems ICX 6430 Hardware Installation Manual

Connecting network devices

Connecting to Ethernet or Fast Ethernet hubs

For copper connections to Ethernet hubs, a 10/100Base-TX or 1000Base-T switch, or another Brocade device, a crossover cable is
required (see the figures below). If the hub is equipped with an uplink port, it requires a straight-through cable instead of a crossover
cable.
NOTE
The 802.3ab standard (automatic MDI or MDIX detection) calls for automatic negotiation of the connection between two
1000Base-T ports. In this case, a straight-through cable may work just as well as a crossover cable. For more information
about this feature, refer to the Brocade FastIron Security Configuration Guide.
