Processing Engines (NPEs)
The Cisco uBR7225VXR currently must contain one uBR7200-NPE-G1 processor that must
have at least 256 MB of DRAM. If it contains more than one BPE, Cisco recommends
installing either 512 MB or 1 GB of DRAM on the uBR7200-NPE-G1 to ensure best
performance.
FE/GE ports availability: 3 GE ports (UBR-NPE-G1).

●
Single or dual redundant power supplies
●
100 to 240 VAC input, 50/60 Hz frequency
●
5.5 A maximum AC input current
●
