Cable Specifications
See “Cable Specifications” on page 6-7 for cable lengths and types supported on the FGS devices.
Connecting to Ethernet or Fast Ethernet Hubs
For copper connections to Ethernet hubs, a 10/100Base-TX or 1000Base-T switch, or another Foundry device, a
crossover cable is required (Figure 4.1 and Figure 4.2). 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/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, see the Foundry FastIron Configuration Guide.
