What is the 450-ADWM Dual Hot-Plug Redundant Power Supply (1+1), 1100W?
A
The 450-ADWM is a dual-module, hot-plug capable power supply delivering 1100W total with 1+1 redundancy for uninterrupted enterprise server and storage operations.
Q
How does hot-plug capability benefit my system?
A
Hot-plug capability allows you to replace or add a power module without shutting down your system, ensuring continuous uptime and operational reliability.
Q
What does 1+1 redundancy mean?
A
1+1 redundancy means two identical 550W modules share the load; if one fails, the other immediately supports the full 1100W output without service interruption.
Q
Which input voltages does the 450-ADWM support?
A
The unit auto-senses and supports 100–240VAC input at 50–60Hz, allowing global deployment without manual voltage selection.

A
Slide each module into the dedicated PSU bay until it latches, connect the input cable, and verify LED status to ensure proper operation.
Q
How can I tell if a module has failed?
A
A failed module triggers a red LED on the front panel and an alarm; the remaining module automatically carries the full load.
Q
What are the operating temperature and humidity ranges?
A
The 450-ADWM operates between 0°C and 50°C at 5–95% non-condensing humidity, supporting most data-center environments.
