EX4100-H Power System

This topic details the power systems (PSUs) and their specifications for the EX4100-H switches.

AC Power Supply Unit in EX4100-H Switches

The EX4100-H-12MP uses 340 W AC and 340 W DC external fanless power supply units (PSUs). You can connect up to two PSUs to the switch.

Note:

This device is designed to support overvoltage category II (OVC II). If the equipment is subjected to transient voltages greater than OVC II, it will need additional external protection. Ensure that the component you use for this external protection complies with IEC 61643/UL 1449 based on the local code.
Note:

EX4100-H switches are designed for Pollution DEGREE II

You can connect the EX4100-H-12MP switch to any one of the following:

  • One external 340 W AC PSU
  • One external 340 W DC PSU
  • Two external 340 W AC PSUs
  • Two external 340 W DC PSUs
  • One external 340 W AC PSU and one external 340 W DC PSU

The AC PSU for the EX4100-H-24MP and EX4100-H-24F switch is a FRU PSU.

Characteristics of the AC PSU

  • The EX4100-H-12MP uses an external 340 W AC PSU.

  • The EX4100-H-24MP uses a FRU 340 W AC PSU.

  • The EX4100-H-24F uses a FRU 90 W AC PSU.

Refer EX4100-H Power System to check the EX4100-H models and their respective external PSUs or FRU PSUs.

Specifications of the Power Cord for AC PSUs for EX4100-H Switches

A detachable AC power cord is supplied with the AC PSUs. The coupler is a custom lug-type. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.

CAUTION:

The AC power cord provided with each power supply is intended for use with that PSU only and not for any other use.
Note:

The power cord of spare PSUs is separately orderable.
Note:

In North America, AC power cords must not exceed 4.5 m (approximately 14.75 ft) in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and with Canadian Electrical Code (CEC) Section 4-010(3).
