Cisco uBR10012 Router Features

The Cisco uBR10012 router has the following features:

•19-inch rack mount, 22.75-inch depth. See “Cisco uBR10012 Router”.

•31.5-inch height, 18 Rack Units (RU)—2 chassis per 7-foot rack

•Twelve card slots:

–8 cable interface line cards

–4 network uplink line cards

•LCD module, see “LCD Module”.

•Performance routing engine (PRE1, PRE2 and PRE4) modules, see “Performance Routing Engine”.

–PRE1 modules support error checking and correction (ECC) for all onboard memory, replacing the simpler parity error algorithm of the original PRE module.

–PRE2 modules are designed to address Internet-service-provider (ISP) requirements. The PRE2 provides 6.2 mpps of processing power and has a 500-MHz RM7000 mips processor with integrated 16-KB data and 16-KB instruction Level 1 caches integrated 256-KB Level 2 cache, and 4-MB Level 3 cache. Cisco IOS Release 12.3(9)BC.

–The PRE4 is the fifth generation Parallel Express Forwarding (PXF) packet processing and scheduling engine for the Cisco uBR10012 router. The PRE4 provides 10 mpps of processing power and has a 800-MHz dual processor with a 512-MB packet buffer and a 128-MB control memory with error-correcting code. Cisco IOS Release 12.3(33)SB.

Note When replacing a PRE1 module with a PRE2 module, you must also install EMI gaskets and RF absorber material, for more information, go to the following URL:

•AC and DC power supply options:

–Dual –48/–60 VDC hot-swappable and redundant power entry modules (DC PEMs). See “DC Power Entry Modules”.

–Dual 200-240 VAC hot-swappable and redundant power entry modules (AC PEMs). See “DC Power Entry Modules”.

–Optional external 100-120VAC-input power shelf with redundant power supply support. For more information go to the following URL:

•Alarm relays: minor, major, and critical.

•Two timing, communication, and control plus (TCC+) modules —each TCC+ card provides a connector for an external clock reference source, with a second connector for a backup clock source. See “Timing, Communication, and Control Plus Card”.

•Fan module—Forced-air convection cooling, see “Cisco uBR10012 Router FRU Resources”.

–Dual-speed fan uses lower speed for when operating at nominal temperatures and high speed when operating at or above recommended operating temperatures.
