4U Rackmount Chassis with Silver Bezel

The iStarUSA D-400SEA-SL-HDD2535 is a 4U server chassis built from 1.2 mm SECC zinc-coated steel with an aluminium-alloy front bezel. It fits a standard 19-inch rack and accepts ATX or microATX motherboards up to 12 by 9.6 inches. Seven low-profile expansion slots are available for add-in cards.

Suited for RAID Storage Builds

This chassis holds one external 3.5-inch bay, two internal 3.5-inch bays and four 5.25-inch bays, giving room for up to five drives in a RAID array when paired with a BPU or T-Series backplane. Builders who need hot-swap trays without a backplane, or who require more than seven expansion slots, should consider a different enclosure.

PS2 or Mini-Redundant Power Supply Support

The unit ships with one 80 mm and one 120 mm fan installed, and an optional second 80 mm fan can be added. Front-panel indicators show power, drive activity, temperature and fan status when a TC-ISF08 sensor board is fitted. A key-locked bezel secures the drives and two USB 2.0 ports provide front access.

Questions about this item

How deep is the 4U rackmount chassis so I know it fits my cabinet?

The unit depth is 20.80 inches, so verify your cabinet provides at least that much clear rail-to-door space before mounting.

Which screws and rails are used to secure the 1.2mm SECC steel chassis in a standard 19-inch rack?

Use the included rack-mount ears and M6 cage nuts on 19.00-inch wide posts; the most common mistake is forgetting the middle screw on each ear, which lets the chassis sag under drive weight.

When do the 80 mm and 120 mm fans typically need replacement in this chassis?

Plan to swap both fans after roughly three to four years of continuous duty; the 80 mm unit is accessible behind the front bezel, while the 120 mm unit requires removing the top cover.
