Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. The first four 10/100 Fast Ethernet ports (FE0/1, FE0/2, FE0/3, FE0/4) on the GRWIC-D-ES-2S-8PC switch module are PoE+ ports.

Note On the GRWIC-D-ES-2S-8PC switch module, the first four 10/100 Fast Ethernet ports (FE0/1, FE0/2, FE0/3, FE0/4) are PoE+ ports. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable. The 100BASE-TX traffic requires Category 5, Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The maximum cable length is 328 feet (100 meters). The 10/100BASE-T ports use RJ-45 connectors with Ethernet pinouts. In all cases, the attached device must be within 328 feet (100 meters). If the connected device also supports auto-negotiation, the switch negotiates the best connection (the fastest line speed that both devices support and full-duplex transmission if the attached device supports it), and configures itself accordingly. When set for auto-negotiation, the switch determines the speed and duplex settings of the attached device, and advertises its own capabilities. You can set the ports for speed and duplex auto-negotiation.

You can set the 10/100BASE-T ports on the switch to operate in any combination of half duplex, full duplex, or 10 or 100 Mb/s. The port labeling for the switch modules is described in Table 1-2 and Table 1-3.ĭual-purpose port (10/100/1000BASE-T port and 100/1000 Mb/s SFP module slot)
