Module Placement In A Matrix E7 Chassis; 100Base-Fx Fiber-Optic Network - Enterasys Matrix 7H4284-49 Hardware Installation Manual

Module Placement in a Matrix E7 Chassis

2.2 MODULE PLACEMENT IN A MATRIX E7 CHASSIS
If you want to mix 6x1xxx, 6x2xxx, 6x3xxx, and 7H43xx-xx series modules in the same Matrix
E7 chassis, it is necessary to have a 7H4382-25, 7H4382-49, 7H4383-49, or 7H4385-49 DFE
module installed and also follow the module placement rules described in
successfully bridge data traffic to some or all modules in the chassis.

100BASE-FX FIBER-OPTIC NETWORK

The 7H4284-49 DFE module provides 48 ports that support 100 Mbps multimode fiber-optic
connectivity via 48 fixed front-panel MT-RJ connectors.
The 48 fixed front-panel ports support 100BASE-FX fiber-optic cabling. The device at the other
end of the fiber-optic segment must meet 100BASE-FX Fast Ethernet network requirements for
the devices to operate at 100 Mbps. IEEE 802.3u 100BASE-FX characteristics for Multimode
Fiber is a segment length of 412 meters (switched port) in half duplex, 2 kilometers (switched
port) in full duplex. This distance will be considerably shorter from a repeater port. Make sure to
check your network diameter specifications. Refer to the Cabling Guide for details.
