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 determine 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 Gigabit 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 that plug into a Gigabit
Ethernet (E1000-2 or E1000-2-G) card to link the port with the fiber-optic network and determine the
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 micron fiber 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.
