Compact 4U rackmount server chassis

The iStarUSA D-400-6-Black is a 4U rackmount server chassis built from 1.2 mm SECC zinc-coated steel with an aluminium alloy front bezel. It accepts motherboards up to 12 by 10 inches and provides seven expansion slots for add-on cards. The black finish suits standard 19-inch rack environments.

Six 5.25-inch bays enable hot-swap storage

Six external 5.25-inch drive bays combine with two external and two internal 3.5-inch bays for a total of ten drive positions. When paired with a compatible backplane the 5.25-inch bays support hot-swappable SAS or SATA drives for RAID configurations. Front-panel USB 2.0 connectors and a lockable bezel add convenient access and physical security.

Standard PS2 or mini-redundant power only

The chassis supports PS2 and mini-redundant power supplies but does not accommodate other form factors. Cooling relies on a single 80 mm fan with a removable air filter; additional airflow planning is required for dense builds. Temperature and fan monitoring depend on an optional sensor board not included with the chassis.

Questions about this item

Will the removable air filter need regular cleaning or replacement?

The chassis includes a removable air filter that should be cleaned periodically to maintain airflow to the 80mm cooling fan.

What limits the number of add-on cards I can install for sustained workloads?

The chassis provides seven expansion slots, which is the maximum number of add-on cards supported.

How much noise and heat does the single 80mm fan produce during all-day operation?

One 80mm cooling fan handles airflow; noise and heat levels will depend on the installed components and ambient temperature.
