To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, the router must be adequately grounded before power is connected.
To ground AC-powered or DC-powered routers, you must connect a grounding cable to
earth ground and then attach it to the chassis grounding points using the two screws
provided. (see Figure 158 on page
Thermal Output (BTUs per hour)
34.5 KW divided by 0.91 * 3.41 = 129,280 BTU/hr
(Zone 0 output. The calculation method for Zone
1 is the same as for Zone 0).
34.5 KW of output power consumed by the chassis.
This is the maximum output the chassis can
consume in a redundant configuration. The input
power is 34.5 divided by 0.91 = 37.9 KW.
