MULTILINK MC-E10 & MC-E100 CONVERTER SWITCH
The various models of DC power type and extended ambient temperature power supplies
are numerous and your choice needs to be called out on your order.
4.6 Powering the Multilink MC-E10 & MC-E100 with 12V, 24V or –48VDC power input
Each Multilink MC-E10 or E100 is reliably equipped with an internal DC power supply, and
has built-in screw terminals for secure attachment of the power leads. Three models
support a range of power input types. The three model choices are for use with 12VDC,
24VDC or -48VDC power. DC power input may be chosen for high-availability.
The extended temperature capability of the DC-powered Multilink MC-E10s or E100s can
go outdoors, rated at –40`C to +75`C. If indoors, the DC jack is also present and optionally
can be used with an external AC power supply.

4.7 Multilink MC-E10 & MC-E100, DC-powered, -48VDC, 24VDC and 12VDC Installation
This section describes the proper connection of the -48VDC leads (or 24VDC, 12VDC leads)
to the DC power terminal block on the MC-E10 & MC-E100 hardened media converter (as
shown in Figure ). The DC terminal block on the MC-E10 & MC-E100 is located on the left
side of the unit and is equipped with three (3) screw-down lead posts. The power terminals
