Cisco 12000 Router Installation Preinstallation Guidelines (ULT 121): Identify preinstallation guidelines for the Cisco 12000 router. • AC−Input Power Supply: Installing (ULT 122): Sequence the steps involved in installing an AC−input power supply.
Cisco 12000 Series GSR: Troubleshooting Startup Problems: Identifying (ULT 171): Identify Cisco 12000 Series Gigabit Switch Router (GSR) startup problems. • Power Subsystem: Troubleshooting (ULT 172): Identify guidelines for troubleshooting the power subsystem.
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.
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.
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.
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.
British thermal unit buffer A temporary storage area, usually in RAM. C.S.C Cisco Systems Capital cage a piece of hardware into which cards are installed CEF Cisco express forwarding Challenge Handshake Authentication Protocol (CHAP) Challenge Handshake Authentication Protocol.
Cyclic redundancy check. Error−checking technique in which the frame recipient calculates a remainder by dividing frame contents by a prime binary divisor and compares the calculated remainder to a value stored in the frame by the sending node. CSC Clock and scheduler card CSU Channel Service Unit.
dynamic random−access memory. RAM that stores in capacitors that must be periodically refreshed. DSU Data Service Unit. Device used in digital transmission that adapts the physical interface on a DTE device to a transmission facility such as T1 or E1.
FRU Field Replaceable Unit Gbps gigabits per second Gigabit Switch Router The Cisco 12000 Gigabit Switch Router is Cisco’s high−performance, carrier−class routing platform for tier 1 Internet Service Providers (ISPs). GRP Gigabit Route Processor GSR Gigabit Switch Router HSSI High−Speed Serial Interface.
Integrated Services Digital Network. ISP Internet Service Provider LAN Local Area Network LED light emitting diode MAC Media Access Control MAU Media Attachment Unit Mbus Maintenance bus. A router's monitoring system. Network Termination (NT1) network termination 1.
OC optical carrier Ohm Ohm's Law is the mathematical relationship among electric current, resistance, and voltage. OSI Open Systems Interconnection Packet over SONET (POS) Packet over Synchronous Optical Network.
reduced instruction set computing ROM read−only memory Route/Switch Processor (RSP) Route/Switch Processor. Processor module in the Cisco 7500 series routers that integrates the functions of the RP and the SP.
SONET Synchronous Optical Network, a standard for connecting fiber−optic transmission systems. Static Random−Access Memory (SRAM) Type of RAM that retains its contents for as long as power is supplied. SRAM does not require constant refreshing, like DRAM.
VIP Versatile Interface Processor. Interface card used in Cisco 7000 and Cisco 7500 series routers. The VIP provides multilayer switching and runs Cisco IOS.
