Network Requirements
2.3
100BASE-TX NETWORK
The fixed front panel ports of the SmartSwitch provide an RJ45 connection that supports Category
5 UTP cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3u
100BASE-TX Fast Ethernet network requirements for the devices to operate at 100 Mbps. Refer to
the Cabletron Systems Cabling Guide for details.
2.4
1000BASE-SX AND -LX NETWORK
The GPIM ports of the 6H262-18 provide fiber optic SC connections that support 1000BASE-SX
and 1000BASE-LX connections. The device at the other end of the fiber optic connection must
meet the necessary 1000BASE-SX or -LX specification requirements for the devices to operate at
1 Gbps. Refer to for cable specifications, and
Section 3.6
for installation instructions.
NOTE
If a port is to operate at 100 Mbps, Category 5 cabling must be used. For 10 Mbps
operation only, Category 3 cabling can be used. Refer to
Section 2.3
for information
about 100BASE-TX networks and cabling.
NOTE
The fixed ports of the SmartSwitch support Category 5 UTP cabling with an impedance
between 85 and 111 ohms for 10 and 100 Mbps operation.
SmartSwitches are capable of operating at either 10 or 100 Mbps. SmartSwitches
automatically sense the speed of the other device and adjusts their speed accordingly.
