APPENDIX B : Internal DC Power Supply Options

B1.0 SPECIFICATIONS FOR MAGNUM 6K16V SWITCHES, DC POWER
Power Magnum 6K16V models, for –48V and 24V DC & 125VDC and 5V
Power input
Each Magnum Model 6K16V Managed Switch (DC option) requires a DC power
source, from for 24VDC, -48VDC and 125VDC option or 5VDC input. The wide range
of power input qualifies this product for use in 24VDC, -48VDC as well as 125VDC or
5VDC environments. The 24VDC, -48VDC or 125VDC or 5VDC power input provides
an Ethernet networking product utilizing a special type of power supply with a proven
high-reliability record to fulfill the DC requirement.

B2.0 -48VDC, 24VDC and 125VDC POWER, THEORY OF OPERATION
The -48VDC, 24VDC and
125VDC power options are designed
using diodes inside on each DC power
input line behind the two external power
connection terminals, so that the power
from an external source can only flow
into the hub. This allows the Switch to operate only whenever DC power is correctly
