Site Requirement Guidelines

AC-Powered Systems

In sites where the Cisco 12012 operates with AC-input power supplies, observe the
following guidelines:
•
The AC-input power supply operating between 185–264 VAC requires a minimum of
20-amp service, North America; 10-amp or 16-amp, International.
•
There are five styles of AC-input power supply power cords available (differing in plug
type); make sure you have the correct style for your site. (See Figure 2-2 and Table 2-3.)
All AC-input power supply power cords measure 14 feet (4.3 m).
•
Provide dedicated power sources for each power supply installed in the router.
•
Install an uninterruptible power source where possible.
•
Install proper grounding to avoid damage from lightening and power surges.
Table 2-2 lists the nominal and acceptable value ranges for source AC power.
