Chapter 3 Installing and Connecting the Router
Connecting Power
Warning When installing the product, please use the provided or designated connection cables/power
cables/AC adaptors. Using any other cables/adaptors could cause a malfunction or a fire. Electrical
Appliance and Material Safety Law prohibits the use of UL-certified cables (that have the “UL” shown
on the code) for any other electrical devices than products designated by CISCO. The use of cables
that are certified by Electrical Appliance and Material Safety Law (that have “PSE” shown on the
code) is not limited to CISCO-designated products. Statement 371 .
Connecting 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 90 and 264 VAC.
Note This product requires surge protection to be provided as part of the building installation. To comply with
the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, an external surge
protective device (SPD) is required at the AC power service equipment.
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:
15A, 120VAC (16A, 240VAC). Statement 1005
