Power Connections
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 Routers 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.
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 relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than:
15A, 120VAC (10A, 240VAC). Statement 1005
Connecting the Router to DC Power
If your router has a DC-input power supply, follow the directions in this section for proper wiring.
Warning
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than:
15A, 60VDC. Statement 1005
Warning
Use copper conductors only. Statement 1025
DC Wiring Requirements
A Cisco router with a DC-input power supply requires copper wire for the power connections. Table 2 summarizes the wiring
requirements for Cisco 2600XM series and Cisco 2612 routers with a DC-input power supply.
Note
For installations compliant with the National Electric Code, AWG 14 (2.0 mm
safety ground wire.
