3U Rackmount Chassis for Compact Server Builds

The iStarUSA D-300SEA-BL-T7SA is a 3U rackmount cabinet built for environments that need a short-depth server platform. Its 1.2mm SECC zinc-coated steel chassis and patented aluminium front bezel with key lock suit small business, branch office or edge deployments where physical security and standard 19.00-inch rack compliance are required.

Drive Capacity and Cooling Headroom

The unit provides four 5.25-inch bays, two external 3.5-inch bays and one internal 3.5-inch bay for mixed storage configurations. A single 60mm fan is fitted as standard; three additional 80mm positions and one extra 60mm slot are available when the DD-FANGUARD-8 bracket is added, allowing airflow to scale with higher-density drives or warmer rooms.

Front-Panel Access and Expansion Flexibility

Two front USB 2.0 ports give direct local access for diagnostics or media without reaching the rear of the rack. Seven full-height expansion slots accommodate add-in cards such as RAID controllers or extra network interfaces, while the chassis accepts both 1U and 2U power supplies to match redundancy or efficiency needs.

Questions about this item

Will the 1U or 2U power supply I already own fit the D-300SEA-BL-T7SA?

The chassis supports both 1U and 2U power supplies, so either form factor will mount without modification.

Which front-panel LEDs confirm the chassis is operating normally after I power it on?

The blue front bezel shows Power and HDD LEDs; Temperature and Fan LEDs also light when the optional TC-ISF08 sensor board is installed.

What drive brackets and cooling parts are included, and what must I add for hot-swap or extra fans?

The box includes two 3.5″ bays, one internal 3.5″ bay, four 5.25″ bays and a single 60 mm fan; hot-swap SATA/SAS 6 Gbps trays and the DD-FANGUARD-8 bracket for three 80 mm fans are optional extras.
