To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the

Caution

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

Cisco 2801 routers are not designed to connect to DC power.

Note

Warning

Read the installation instructions before connecting the system to the power source. Statement 1004

The installation must comply with all required electrical codes applicable at the installation site.

Note

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
