2.2100BASE-FX NETWORK
The fixed ports (1 through 16) of the 2H258-17R provide fiber optic multimode connections via MT-RJ connectors. Segments connected to these ports must meet the optical performance requirements for 100BASE-FX IEEE 802.3u. The front panel slot for optional modules can also support Enterasys Networks fiber optic interface modules. The device at the other end of the segment must meet the 100BASE-FX Fast Ethernet network requirements to operate at 100 Mbps. Refer to the Enterasys Networks Cabling Guide for details.
