Connecting Network Devices

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

Connectors

See “Cable length summary table” on page 2-7

For port pinouts, see the section “Pinouts and Signaling” on page 2-6.

Cable Specifications

See “Cable Specifications” on page 2-7for cable lengths and types.

Connecting to Ethernet or Fast Ethernet Hubs

For copper connections to Ethernet hubs, a 10/100BaseTX or 1000BaseT 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 X-Series Configuration Guide or the Foundry Switch and Router Installation and Basic Configuration Guide.
