Chapter 2 Preparing to Install
Site Preparation
• For the IGX node and peripheral equipment to function safely and correctly, use only the power
cords, cables, and connectors that are specified for the equipment and make sure that they are in
good condition.
• Use a wrist strap when handling cards.
Power and Grounding
This section lists the requirements that relate to electrical power and grounding. These requirements
cover installations at central office (CO) and private enterprise locations.
AC Power Circuit Breakers
For an AC-powered system, verify that the node’s power comes from a dedicated AC branch circuit. The
circuit must be protected by a dedicated, two-pole circuit breaker. The circuit breaker must have a rated
current and trip delay that is greater than those of the IGX circuit breaker. Cisco Systems recommends
the following:
• For IGX 8420 or IGX 8430 nodes, the site should have a 20A, 2-pole AC circuit breaker with a long
trip-delay at each branch circuit.
• For IGX 8410 nodes, the site should have a 15A, 2-pole AC circuit breaker with a long trip-delay at
each branch circuit.
The IGX 8420 and IGX 8430 nodes use a 20A, 2-pole circuit breaker for each AC input. The
manufacturer of this circuit breaker is ETA, and the ETA part number for the circuit breaker is
8340-F120-P1P2-B2H020A. The IGX 8410 node uses a 15A, 2-pole AC circuit breaker on each input.
This circuit breaker comes from either ETA (part number 8340-F120-P1P2-B2H015A) or Airpax (part
number IEGH11-1-62-15.0-91V).
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that
the protective device is rated not greater than:
120 VAC, 15A U.S. (240 VAC, 10A international)
To see translations of this warning, refer to the Regulatory Compliance and Safety Information
document that accompanied this product.
DC Power Circuit Breakers
For a DC-powered system, verify that the node’s power comes from a dedicated DC branch circuit. The
circuit must be protected by a dedicated circuit breaker. The circuit breaker must have a rated current
and trip delay that is greater than those of the IGX circuit breaker. Cisco Systems recommends that the
site have a dedicated 25A, 1-pole circuit breaker with a medium trip delay at each branch circuit.
The DC-powered nodes use a 25A, 1-pole circuit breaker with a short trip delay on each –48V input. The
manufacturer of this circuit breaker is ETA, and the ETA part number is 8340F110P1K1A2H00025.
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that
the protective device is rated not greater than:
25A minimum, 60VDC
