3.2.1 AC/DC power supplies
The payShield 10K is equipped with dual power supply units allowing the HSM to receive power from two
independent supplies. This redundancy is designed to help prevent any operational break in the event of:
•
An outage in either one of the power supplies
•
Failure of either of the power distribution units within the HSM
Each supply has the following features:
•
450W power factor corrected high efficiency supply
•
Universal AC Inlet, 90 to 264V 50/60 Hz
•
12V main output and 5V standby
•
Over-voltage, over-current, over temperature protection
•
Latching mechanism to hold the supply in place
•
Internal variable speed fan for independent cooling
•
Integral LEDs to provide operational status
•
Management, status, and control signals on the internal interface
3.2.1.1 Swapping out the Power Supply
Note:
The power supplies can be independently removed and replaced without removing the mains power from the
other power supply. Each has a positive retention latch and status indicators.
1. Remove the AC supply cord from the PSU that you will be removing.
Note:
This is an important safety issue so you are not left holding a PSU that is still connected to the mains.
