Agency compliance
The S4048–ON is designed to comply with the following safety and agency requirements.
Network Equipment Building Systems Compliance
• Use shielded cables for ports from 0 to 48. Ground the shields at both ends.
• Use only reverse airow congurations in a NEBS-compliant installation.
• Fit the power supplies and fan modules with lter kits. Replace the fan lters 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.
