Step 4

Plug the AC power cord into a single-phase wall outlet rated for a nominal voltage.

For an IGX 8410 node, the AC voltage should be from 200 to 240 VAC or 100 to

120 VAC. The outlet must also be capable of supplying up to 12 amperes (A) (13 A in the UK). The

building circuit should be protected with a 15 A or 20 A circuit breaker.

For an IGX 8420 or 8430, the AC voltage should be between 200 and 240 VAC. Each outlet must also

be capable of supplying up to 16 A (13 A in the UK, where the plug has a built-in, 13 A fuse). In

North America, the building circuit should be protected with a 20 A circuit breaker.

Step 5 For the dual power feed version, plug each power cord into a receptacle that connects to a separate

building circuit to provide backup if one building circuit fails. Each building circuit should have a 15 A

or 20 A circuit breaker.

Step 6 The ground (green) wire of the AC power cord is connected to the IGX for safety ground. Make sure that

each AC receptacle in the building is grounded.

Step 7 In addition to the preceding, Cisco recommends that you provide an AC power strip with at least four

outlets. Place the strip near the IGX to supply optional modems, CSUs, DSUs, or test equipment. Be sure

to connect this power strip to an AC source voltage that is standard for the region (for example, 115 VAC

in North America or 230 VAC in Europe).

Note Neither the AC power supplies nor any other components have test points for checking power supply

voltages. For a visual check when power is on, observe whether the AC OK LED and DC OK LED are

lit. Also, use the dsppwr command to check the state of power supplies.

DC Power Connections

A system that uses a DC power source has one or two configurations, as follows:

• IGX 8410 node

–

Single power source

–

Dual power source (a separate branch circuit supplies each source)

• IGX 8420

–

Single power source

–

Dual power source (a separate branch circuit supplies each source)
