Procedures Cisco 12000 Series GSR Routers Cisco 12000 Router Installation AC−Input Power Supply: Installing Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets. • Verify that the power supply power switch is in the STANDBY position. • Slide the power supply into the vacant bay, using two hands to support [...]

System Startup Turn each system power switch to the ON position. • Check that the blower modules are operating by listening for them. • As the GRP boots, observe the GRP alphanumeric LED displays. • As the line cards boot, observe the alphanumeric LED indicators on each line card. Line cards boot from left to right. • Boot the Cisco IOS sof[...]

Router Card: Installing Connect the switch to a computer or other data terminal equipment (DTE) device. • Connect the EIA−232 cable to the console, the DB−9 connector, on the switch. • Use the console configuration default settings for communication with the switch. • Power up the switch. • At the Greeting screen, press Return to enter [...]

data terminal equipment. Device at the user end of a user−network interface that serves as a data source, destination, or both. DTE connects to a data network through a DCE device (for example, a modem) and typically uses clocking signals generated by the DCE. DTE includes such devices as computers, protocol translators, and multiplexers. 10BaseT[...]
