Allied Telesis AT-PWR800-90 800W Power Supply – US Federal Version
Overview
The AT-PWR800-90 is an 800W internal power supply designed as a direct replacement or redundant second supply for compatible Allied Telesis chassis-based switches and routers. The US/LF (Lead-Free) Federal version satisfies federal procurement requirements that mandate RoHS-compliant, lead-free hardware — a non-negotiable for government facility deployments and federally funded network infrastructure projects. If your chassis supports dual power supplies for N+1 redundancy, adding the AT-PWR800-90 eliminates a single PSU as a single point of failure, keeping the network stack running through a supply fault without a maintenance window.
Compatibility
The AT-PWR800-90 is designed for use with Allied Telesis chassis-based platforms that accept an 800W hot-swap power module in the US power configuration. Confirm your specific chassis model against Allied Telesis's compatibility matrix before ordering — PSU form factors and wattage slots vary across the SwitchBlade x908, x950, and related chassis families. Mixing wattages within a dual-PSU chassis is not supported on most platforms; both supplies should match at 800W. Verify the chassis bay count and whether your deployment requires a second supply for load sharing versus pure redundancy, as this affects whether 800W is the correct capacity tier for your port density and PoE budget.
Installation Notes
Installation is a tool-free hot-swap procedure on supported chassis — slide the unit into the vacant PSU bay and secure the retention latch. Confirm the chassis is powered and operational before insertion if installing as a redundant second supply; hot-swap capability means no planned downtime is required. The US version is wired for standard North American AC input; do not install in non-US voltage environments without verifying input voltage range from the Allied Telesis datasheet for this SKU. The LF (Lead-Free) designation is a material compliance attribute, not an installation constraint.
