The Cisco 2811 is one of four Cisco 2800 Series routers, with the 2801, 2821 and 2851, and is ordered as CISCO2811 with AC power. CISCO2811-AC-IP adds power over Ethernet distribution, and CISCO2811-DC takes DC power. The router has two onboard 10/100 Fast Ethernet ports, four interface card slots, one network module slot, two onboard AIM slots, two PVDM slots and up to two USB ports. Wall mounting is supported. It starts with 256 MB of DRAM and 64 MB of flash, and DRAM goes to 768 MB.
The four interface card slots take HWIC modules and also WIC, VIC and VWIC cards, and two slots can be combined for a double-wide HWIC-D. Each HWIC slot offers up to 400 Mbps half duplex or 800 Mbps aggregate. The network module slot takes NM and NME modules, including the NME-16ES-1G and NME-16ES-1G-P EtherSwitch service modules. PVDM2-8, PVDM2-16, PVDM2-32, PVDM2-48 and PVDM2-64 fit the two PVDM slots, and the AIM slots take AIM-ATM, AIM-COMPR2-V2, AIM-CUE and AIM-VPN/EPII-PLUS. HWIC-16A and VWIC2-2MFT-T1/E1 are among the interface cards that Cisco supports on the 2811.
The in-line power upgrade to the internal supply feeds PoE-capable switch modules and HWICs, with up to 160 W of power distribution on the 2811. An optional DC supply is available, and an external connector on the chassis accepts a redundant power supply that can be shared with other Cisco products. CISCO2811 ships with Cisco IOS IP Base, and the IP Voice, Enterprise Base, Enterprise Services and SP Services feature sets are ordered as S28NIPV, S28NEB, S28NES and S28NSPSK9 for the 2811, 2821 and 2851. The Cisco 2901, Cisco 2911 and Cisco 1841 pages cover related routers, and the full range is on the networking page.
