Power Sub-System
2.1.1

Hot Swapping Power Modules

The Storage System SSR212MA power supply assembly is capable of supporting hot swapping
of power supply modules in a 1+1 configuration.
2.1.2

Power Supply Outputs

The Storage System SSR212MA power system supports one or two 500 W Power Supply
module's in a 1+1 redundant configuration. The power supply module provides five DC output
rails; +12V1, +12V2, +12V3, -12V, +5VSB, while the Power Supply Enclosure provides two DC
output rails: +3.3V and +5V.
Table 5. Enclosure & Module Output Summary (500W 10 second peak ratings)
+3.3V
20A
NOTE: The total combined power for +3.3V & +5V should not exceed 120W. The total combined power for +12V, -
12V, 5VSB should not exceed 360W.
The module provides a handle to assist in insertion and extraction and can be inserted and
extracted without the assistance of tools.
2.1.2.1 Power Supply LED Indicator
The power supply module provides a single external bi-color LED to indicate the status of the
power supply. When AC is applied to the Power Supply Unit (PSU) and standby voltages are
available, the LED will blink green. The LED will be solid on green to indicate that all the power
outputs are available. The LED will be solid on amber to indicate that the power supply has
failed, shutdown due to over current, shutdown due to over temperature, or is indicating a
predictive failure. Refer to the following table for conditions of the LED.
