Connecting to the Network

The following procedures cover the cable connections from the network or other devices to the switch RJ45 ports or any installed optional Mini‐GBIC.

Connecting UTP Cables

The fixed RJ45 front panel ports (ports 1 through 24) are 10/100 Mbps ports and have auto polarity detect. The two front panel 1000 Mbps stacking ports, ports 25 and 26, which can be configured as standard Gigabit Ethernet ports, also have auto polarity detect. Refer to the SecureStack A2 Configuration Guide for information about configuring standalone A2 stack ports.

When connecting a workstation to these ports, use a straight‐through cable. When connecting networking devices to these ports, such as a bridge, repeater, or router, it is not necessary to use a crossover cable.

Note: All fixed RJ45 front panel ports support Category 5 Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. Category 3 cable may be used if the connection is going to be used only for 10 Mbps.
