8608GTE and 8608GTM modules 27Type Label Color/State MeaningGreen/Steady The module has completed its power-onself-test and software initialization andis operating normally.Amber/Steady The module failed its power-on self-test.Module OnlineOff The switch power is off. If the switchpower is on, the module is going throughits power-on self-test and softwareinitialization. A module in this state isnot yet functional.The 8608GBE module supports up to 32 000 table entries in its forwardingengine. For information about table entry characteristics, see NetworkDesign Guidelines (313197-E).The 8608GBM module is an M module and supports up to 128 000 tableentries in its forwarding engine, allowing for large Layer 2 and Layer 3configurations, including Internet routing tables. For information about tableentry characteristics, see Network Design Guidelines (313197-E).The Metro Ethernet Routing Switch 8600 system has three hardwareoperating modes:• Default mode (32 000 table entries) supports up to 32 000 hardwarerecords. This mode supports all modules.• M mode (128 000 table entries) supports up to 128 000 hardwarerecords. This mode supports M modules only.• R mode supports up to:— 256 000 IP routes— 64 000 MAC entries— 32 000 Address Resolution Protocol (ARP) entriesThis mode supports R modules only.The 8608GBE module does not support R or M mode. The 8608GBMmodule supports R and M mode. For specific R and M mode configurationrequirements, see "R mode configuration requirements" (page 24) and "Mmode configuration requirements" (page 23).8608GTE and 8608GTM modulesBoth the 8608GTE and 8608GTM module ("8608GTE/8608GTM module"(page 28)) provide eight 1000BaseT, copper Gigabit Ethernet ports with8-pin modular (RJ-45) connectors. Each port operates in 1000 Mb/s(1 Gb/s) full-duplex mode and supports IEEE 802.3 1998 Clause 28Nortel Metro Ethernet Routing Switch 8600Installation — ModulesNN46220-306 02.02 Standard4.2 7 July 2008Copyright © 2005-2007, Nortel Networks.
