Chapter 3 Installing the Router
Power Connections
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
Caution To comply with Telcordia NEBS GR-1089-Core and EN 300386 requirements, you must use foil
twisted-pair cable that is properly grounded at both ends.
Connecting Routers to a DC-Input Power Supply
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
Warning Use copper conductors only. Statement 1025
Note The installation must comply with the 1996 National Electric Code (NEC) and other applicable codes.
If your router has a DC-input power supply, follow the directions in this section for proper wiring.
A router with a DC-input power supply has a terminal block for the DC power connections.
Depending on the type of router you are installing, see one of the following procedures:
• Wiring the DC-Input Power Supply in Cisco 3725 Routers, page 3-12
• Wiring the DC-Input Power Supply in Cisco 3745 Routers, page 3-17
