Before Configuring Your Network
Before you configure your network, consider your:
Plans for expansion – If the network expands beyond a certain
size, you may need to add additional internetworking devices.
Maximum cable length – Cabling requirements include:
100 Ohm 2-pair Category 5 UTP for up to 100 meters (328 feet)
100 Ohm STP for up to 100 meters (328 feet)
Management access – For in-band management through the
DMM, SNMP and TELNET require another type of Downlink
Fastmodule, SwitchModule, or 10BASE-T Ethernet module and
network monitor card installed in the hub.
Out-of-band management requires Serial Line Interface
Protocol (SLIP) (includes SNMP, TELNET) and Direct Asynchronous
terminals.
