Network Equipment Building Systems 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 regularly.
● 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.
