Estimating Power Requirements
Use the following formula to estimate total power consumption for each deployed chassis.
Use these estimates as a guide. Obey all cable and power safety regulations and assure that they are
sufficient for your system's requirements.
Note
(Total Application Card Maximum Power Load) + (Total Line Card Maximum Power Load) + Chassis
Maximum Power Load = Total Power Consumption
For example, the calculation for estimating the power required for an ASR 5000 installation with (3) PSC2s,
(2) SMCs, (2) SPIOs, (2) RCCs, and (4) GLC2s would be:
(325W x 3) + (130W x 2) + (20W x 2) + (13.5W x 4) + 800W = 2129W
Mounting Requirements
Each 24.5 in. (62.23 cm.) height chassis requires 14 Rack Units (RUs) of space. You can mount the system
into any 19-inch (482.6 mm) equipment rack or telco cabinet with the mounting brackets supplied with the
chassis. Additional hardware (not supplied), such as extension brackets, may be used to install the chassis in
a standard 23-inch (584.2 mm) cabinet or rack. Both front and mid-mount installations are possible, depending
on the position of the mounting brackets on the chassis.
You can mount a maximum of three ASR 5000 chassis in a 2- or 4-post equipment rack or telco cabinet,
provided that all system cooling and ventilation requirements are met. Three stacked chassis will occupy a
minimum of 42 RUs.
When planning chassis installation, ensure that equipment rack or cabinet hardware does not hinder air
flow at any of the intake or exhaust vents. Also, make sure that the rack/cabinet hardware, as well as the
ambient environment, allow the system to function within the required limits. For more information, refer
