Magnum 6K25e Gigabit Fiber Switch Installation and User Guide (10/07)

The -48VDC terminal block on the Magnum 6K25e Switch, as shown in Fig C5.0 is

located on the right rear of the unit and

 

 

 

is equipped with five (5) screw-down

A+ A-

lead posts. If it is the reverse model it

 

 

 

is located on the left rear. The primary

 

 

 

terminals are identified as positive

 

 

 

(A+), negative (A-), and the secondary

 

36-70VDC

 

power terminals as negative (B-),

positive(B+). The chassis “earth” or ground (GND) is a threaded post with a #6 nut. The Dual Source terminal block for the 24VDC and 125VDC are similar.

Figure C5.0: -48VDC Dual-Source, wiring connections to the External Terminal Block on a Magnum 48VDC with Dual-Source option

Note: The GND should be hooked up first. The 6K25e unit has a floating ground, so the user may elect to Ground either + or = terminal to suit the customer’s use.

Before connecting hot lines to the Terminal Block of –48VDC, 24VDC or 125VDC, always use a digital voltmeter to measure the output voltage of the power supply and determine the lead which is more “+ve potential”. The more “+ve” voltage lead from 48V or –48V supply must be connected to the post labeled “+”.

The connection procedure is straightforward. Simply connect the DC leads to the Switch’s power terminals, positive (+) and negative (-) screws. The use of Ground (GND) is optional; it connects to the Switch chassis. Ensure that each lead is securely tightened.

The 24VDC & 125VDC terminal block on Magnum 6K25e’s is similar to that described in the –48VDC information above.

C5.1 UL Requirements

The following must be adhered to in order to conform to UL requirements:

1.Minimum 18 AWG cable for connection to a Centralized DC power source.

2.Minimum 14 AWG cable for connection to earthing wiring.

3.Use only with Listed 10 A circuit breaker provided in building installation.

4.“Complies with FDA radiation performance standards, 21 CFR subchapter J.” or equivalent.

5.Fastening torque of the lugs on the terminal block: 9 inch pound max.

6.Centralized DC Power Source cable securement, use at least four cable ties to secure the cable to the rack at least 4 inches apart with the first one located within 6 inches of the terminal block.

C6.0 ORDERING INFORMATION

To order the optional Dual-Source -48VDC power supply factory installed, order “Dual-Src48V” as a separate line item following the product model.

Example: Magnum 6K25eR-48VDC

Dual-Src-48Vfor the regular DS model with no ON-OFF switch or Dual-Src48V-SWITCHwith the ON-OFF manual switch.

Similarly, order the “Dual –source 24VDC” or “Dual-source 125VDC” as a separate line item following the product model.

Example: Magnum 6K25eR-24VDC or Magnum 6K25eR-125VDC
