Agency compliance
The S4048–ON is designed to comply with the following safety and agency requirements.
Network Equipment Building Systems (NEBS) Compliance
•
Use shielded cables for ports from 0 to 48. Ground the shields at both ends.
•
Use only reverse airflow configurations in a NEBS-compliant installation.
•
Fit the power supplies and fan modules with filter kits. Replace the fan filters on a regular basis.
•
Use this equipment with an external, second-level 6 kV lightning surge protective device (SPD) at the AC input of the building.
•
Use an SPD with the AC power connections to protect the AC power supplies from damage from excessive power line surges.
•
In order to comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC Power Ports, use an SPD at the AC input of
the router.
WARNING:
ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the S4048-ON and its components.
