Chapter 1 Cisco uBR10012 Universal Broadband Router Overview
Cisco uBR10012 Router Features
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 100-120 VAC-input power shelf with redundant power supply support. For

• 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.
