Ethernet Connections
Ethernet connections use either RJ45 (electrical) or mini-GBIC (optical) interfaces. All Ethernet connections are
located on the faceplate. Refer to Figure 1 through Figure 3.The number and type available for each product in
the GLM series is discussed in Section 2.1.3, GLM System Capabilities.
The activity and speed of each port is indicated separately, as documented in Section 3.6, LED Operation.
RJ45 Connections
GLM Switches use standard RJ45 connectors for their electrical interfaces. For example, on GLM082, Ports 1-8
are electrical only.
•
To connect to a PC, use a straight-through or a cross-over Ethernet cable
•
To connect the GLM Switch copper port to an Ethernet device, use UTP (Unshielded Twisted Pair) or
STP (Shielded Twisted Pair) Ethernet cables.
