2 Overview
The Cisco 2800 series integrated services routers include the Cisco 2801, Cisco 2811, Cisco 2821, and Cisco 2851 routers. These
routers differ as follows:
•Cisco 2801 routers support 2 HWIC/WIC/VIC/VWIC slots capable of supporting double-wide HWICs, 1 WIC/VWIC/VIC
slot, 1 VWIC/VIC (voice only) slot, 2 advanced integration modules (AIM), 2 packet voice data modules (PVDMs), 2 Fast
Ethernet connections, and 16 ports of IP phone power output.
•Cisco 2811 routers support 1 single network module enhanced (NME), 4 single or 2 double high-speed WAN interface cards
(HWICs), 2 AIMs, 2 packet voice data modules (PVDMs), 2 Fast Ethernet connections, and 24 ports of IP phone power
output.
•In Cisco 2821 routers, the network module slot adds support for a single network module enhanced extended (NME-X),
and an additional slot supports an extension voice module (EVM); 3 PVDMs are supported; the LAN ports support 2
Gigabit Ethernet ports; and 36 ports of IP phone power output are available.
•In Cisco 2851 routers, the network module slot adds support for network module double-wide (NMDs) and network
module enhanced extended double-wide (NME-XDs), and the IP phone power output is increased to 48 ports.
Note A high density extension module (HDEM) operates in the EVM slot on the Cisco 2821 and Cisco 2851 routers.
The EVM slot supports additional voice services and density without consuming the network module slot on those
routers.

Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the
built in Gigabit Ethernet ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must
be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or
subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces
are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue
4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient
protection in order to connect these interfaces metallically to OSP wiring.
Power Connections
This section describes procedures for connecting your router to AC power, DC power, and backup power. See the appropriate
subsection:
•Connecting the Router to AC Power, page 20
•Connecting the Router to DC Power, page 21
•Connecting the Router to Backup Power, page 26
Note Cisco 2801 routers are not designed to connect to DC power.
Warning Read the installation instructions before connecting the system to the power source. Statement 1004
Note The installation must comply with all required electrical codes applicable at the installation site.
Connecting the Router to AC Power
If your router uses AC power, connect it to a 15 A, 120 VAC (10 A, 240 VAC) circuit with overcurrent protection. If backup
power is required, see the “Connecting the Router to Backup Power” section on page 26.
Note The input voltage tolerance limits for AC power are 85 and 264 VAC.
Warning AC connected units must have a permanent ground connection in addition to the power cable ground wire.
NEBS-compliant grounding satisfies this requirement. Statement 284
Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation.
Install only in accordance with national and local wiring regulations. Statement 1045
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than:
120 VAC, 15 A (240 VAC, 10 A). Statement 1005
