Inbouwframe Icy Dock MB491SKL-B

The ICY DOCK ToughArmor EX MB491SKL-B is a 3.5" carrier panel designed to hold a single 2.5" SATA or SAS HDD/SSD in systems where space is limited and drive security is required. Constructed from full metal, the unit fits in a 3.5" bay and accepts 2.5" drives with a height of 7–15 mm. It supports SATA and SAS at up to 6 Gbps (backwards compatible with 3 Gbps SATA) and includes features intended for industrial and mobile applications.

Advantages

The full-metal construction provides a durable enclosure suitable for harsh environments and meets flammability expectations for industrial use. A removable drive tray enables hot-swap maintenance and quick drive replacement to reduce downtime. Dual-layer physical security — a metal key lock on the tray plus a thumb screw lock that secures the tray to the chassis — reduces unauthorized access and minimizes vibration during transport. Additional design elements such as an anti-dust flap, EMI grounding, multi-flow passive cooling and Active Power Technology for per-bay LED control improve reliability and usability in enterprise and embedded systems.

Suitable for

• Industrial small form factor PCs
• Embedded and automation systems
• Surveillance and mobile DVR systems
• Aerospace and mobile server deployments
• Military and law enforcement equipment

How to use

Insert a compatible 2.5" SATA or SAS drive (7–15 mm height) into the removable tray, secure the drive with the tray screws, then lock the tray with the metal key if required. Slide the tray into a 3.5" drive bay until the thumb screw engages to lock the tray to the chassis. Connect the system to a compatible SATA or SAS host (SAS host required for SAS drives). The tray supports hot-swap operations, allowing you to replace drives while the system is running if the host and OS support hot swapping.

Recommendations

Use the metal key lock to prevent unauthorized access and engage the thumb screw to minimize vibration during transport. For SAS drives, ensure a SAS host connection; for optimal cooling, allow airflow around the carrier and periodically check the anti-dust flap if the device is unused for extended periods.
