9.1.1 E100T-12/E100T-G
E100T-12/E100T-G cards provide twelve switched, IEEE 802.3-compliant 10/100 Base-T Ethernet
ports. Ports detect the speed of an attached device by auto-negotiation and automatically connect at the
appropriate speed and duplex mode, either half or full duplex, and de termine whether to enable or disable
flow control. An E100T-12/E100T-G card consumes 55 W, 1.46 AMPS, and 188 BTU/Hr.
9.1.2 E1000-2/E1000-2-G
E1000-2/E1000-2-G cards provides two switched, IEEE 802.3-compliant Gi gabit Ethernet (1000 Mbps)
ports that support full duplex operation. An E100T-12/E100T-G card consumes 60 W, 1.25 AMPS, and
205 BTU/Hr.
Gigabit interface converters (GBICs) are hot-swappable input/output devices th at plug into a G igabit
Ethernet (E1000-2 or E1000-2-G) card to link the port wit h the fib er-opti c ne two rk an d determ i ne t he
maximum distance that the Ethernet traffic will travel from the E1000-2/E1000-2-G card to the next
network device.
E1000-2/E1000-2-G cards support two types of standard Cisco GBICs: the IEEE 1000Base-SX
compliant 850 nm “short reach” and the IEEE 1000Base-LX compliant 1300 nm “long reach.” The 850
nm SX optics are designed for multimode fiber and distances up to 220 meters on 62.5 mi cr on f ib er and
up to 550 meters on 50 micron fiber. The 1300 nm LX optics are designed for single-mode fiber and
distances up to 5 kilometers.
