Site Requirement Guidelines

Power Connection Guidelines

Cisco 12006 and Cisco 12406 Routers can be configured with either an AC-input power subsystem or a DC-input power subsystem. Site power requirements differ depending on which source power scheme is used. Follow these precautions and recommendations when planning power connections to the router:

•Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power.

•If necessary, install a power conditioner.

•Install proper grounding to avoid damage from lightning and power surges.

Note When operating your router on a single power module, the second power module bay must have a blank filler (MAS-GSR-PWRBLANK=) installed to ensure EMI compliance.

Power Connection Guidelines for AC-Powered Routers

When the Cisco 12006 or Cisco 12406 Router operates with an AC PDU, observe these guidelines:

•A power factor corrector (PFC) allows the PDU to accept AC power source voltage from an AC power source operating between 100 and 240 VAC, 20A service in North America; and a range of from 185 to 264 VAC, 16A service, in an international environment.

•Use only the 14-foot (4.3-meter) AC power cords shipped with the system.

•Provide a dedicated power source with its own circuit breaker for each AC-input power supply installed in the router.

•Install an uninterruptable power source where possible.

Power plug types used in North America, Australia, and Europe are described in Table 2-1and shown in Figure 2-3.
