Connecting Network Devices
Foundry devices support connections to other vendors’ routers, switches, and hubs, as well other Foundry
devices.

Cable Specifications

See “Cable Specifications” on page6-7 for cable lengths and types supported on th e 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.
