480 W AC-DC PSU
Part number 16920 is compatible with all ISW-Series switch models.
The AC-DC power interface is a 6-pin terminal block with polarity signs on the top panel
on most of the ISW-Series switches. The 6-pin terminal block contains an alarm contact
in the middle of the terminal block. The power interface for the ISW 24GbP, 4-SFP
model switch is a 4-pin terminal block with polarity signs on the rear panel.
Use the following steps to install the power supplies:
1. Verify that the power source circuit is de-energized.
2. Connect the DC output terminals on the power supply to the DC input terminals
on the switch. Insert the positive and negative wires into V+ and V- contacts on the
terminal block respectively and tighten the wire-clamp screws to prevent the wires
from being loosened.
