IGX Power Consumption by Card Type
IGX Power Consumption by Card Type
This section contains information on power consumption by individual IGX front card type.
Power input voltage: AC system: Normal operating range is 200–240 VAC, 47 to 63 Hz.
The under and over-voltage range is 180–254 VAC.
DC system: –42 to –56 VDC.
Each AC supply can provide up to 875W to a card shelf. Cabinet
has space for six AC power supplies.
Note Three of the six available AC power supply slots should
be used for power redundancy.
Current requirements: Configuration-dependent: Use Network Design Tool for exact
requirements. For planning purposes, use the following:
• AC system IGX 8420/8430 node: 12A at a nominal voltage of 200 VAC. At
the under-voltage limit of 180 VAC, the current draw is a
maximum of 16A.
• DC system IGX 8420 node: 24A max. per circuit at –42 VDC (worst case)
IGX 8430 node: 44A at nominal –48 VDC; 50A maximum per
circuit at –42 VDC.
Input AC power
connector:
AC power distribution unit is the same for all cabinets: IEC 16A
input connector. Six different power cords available, depending
on country of destination. See the “Power Cabling” section on
page A-47.
DC input connections: DC power is the same for all IGX 8420 and IGX 8430 cabinets
shipped.
DC: 3-screw pluggable terminal connectors.
Operating environment: 0 to 40°C (32 to 104° F) normal operation (50°C or 122° F up to
72 hours). 10 to 85 percent relative humidity, non-condensing.
Shock: Withstands 10 G, 10 ms. at 1/2 sine wave.
Vibration: Withstands 1/4 G, 20 to 500 Hz.
Heat transfer to room: IGX 8420 node: 4300 Btus max, AC-powered system; 3600 Btus
in a DC-powered unit.
IGX 8430 node: 8600 Btus max, AC-powered system; 6800 Btus
in a DC-powered unit.
