NOTE: The 802.3ab standard calls for automatic negotiation of the connection between two 1000BaseT ports.
Consequently, a crossover cable may not be required; a straight-through cable may work as well.
Connecting to Workstations, Servers, or Routers
Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or routers using
network interface cards (NICs).
Fiber cabling is required for direct attachment to Gigabit NICs or switches and routers via fiber ports. See
"Connecting to a Fiber Port" on page 4-16.
Automatic MDI/MDIX Detection
All 100/1000 Ethernet Copper ports on the Foundry FastIron devices support automatic Media Dependent
Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This feature is enabled on all 100/
1000 copper ports by default and cannot be disabled.
Connecting to a Fiber Port
For direct attachment from the Foundry device to a Gigabit NIC, switch, or router, fiber cabling with an LC
connector is required.
To connect the Foundry device to another network device using a fiber port, you must do the following:
