Network Requirements

Before installing the module, review the requirements and specifications referred to in this chapter concerning the following:

•SmartTrunk ( Section 2.1)

•100BASE-FX Fiber Optic Network ( Section 2.2)

The network installation must meet the requirements to ensure satisfactory performance of this equipment. Failure to do so will produce poor network performance.

2.1SmartTrunk FEATURE

Before connecting the module to a network so it can take advantage of the SmartTrunk feature, there are certain rules concerning port connections and configurations that must be followed for proper operation. Refer to the MATRIX E7 Series and SmartSwitch 6000 Series Modules Local Management User’s Guide for additional information.

2.2100BASE-FX FIBER OPTIC NETWORK

The front panel ports of the module provide connections that 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.
