Connecting network devices
Brocade devices support connections to other vendors’ routers, switches, and hubs, as well other
Brocade devices.
Cable specifications
Refer to “Cable specifications” on page 151 for cable lengths and types.
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 (Figure 41 and Figure 42). If the hub is equipped with
an uplink port, it will require 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. Therefore, a crossover cable may not be required; a
straight-through cable may work as well. For more information about this feature, refer to the
FastIron Configuration Guide.
