Agency Compliance
Network Equipment Building Systems (NEBS) Compliance
• Use shielded cables for ports 0 - 43. You must ground the shields at both ends.
• Use only reverse airflow configurations in a NEBS-compliant installation. Use only AC supply
S55-PWR-AC-R, DC supply S55-PWR-DC-R and Fan Only S55-FAN-R, Systems S55-44T-AC-R and
S55-44T-DC-R.
• Fit the power supplies and fan modules with filter kits (S55-PWR-FLTR). You must replace the fan
filters on a regular basis.
• Use this equipment with an external, second-level 6kV lightning Surge Protective Device (SPD) at the
AC input of the building.
