Agency Compliance

The S60 system is designed to comply with the following safety and agency requirements.

Network Equipment Building Systems (NEBS) Compliance

• Use shielded cables for ports 0 - 43. The shields must be grounded at both ends.

• You can only use reverse airflow configurations in a NEBS-compliant installation. Use only supported

Dell S60 AC power supply units, DC power supply units, and fans.

• You must fit the Power Supply Units (PSUs) and fan modules with the supported Dell S60 filter kits.

You must replace the fan filters on a regular basis.

• Use this equipment with an external second-level 6kV lightning Surge Protection Device (SPD) at the

AC input of the building.

• For the NEBS-compliant installation, in order to protect the AC PSUs from damage due to excessive

power line surges, AC power connections must use a SPD.

• In order to comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC Power

Ports, use an external SPD at the AC input of the router.
