MB491SKL-B_Industrial Rugged Full Metal 2.5” SATA/SAS HDD & SSD Mobile Rack for External 3.5" Drive Bay with Key Lock & Thumb Screw Design

The ICY DOCK ToughArmor EX MB491SKL-B 2.5” mobile rack is MIL-STD-810G certified and built specifically for military and industrial computing systems that require exceptional drive security. It uses a rugged, heavy-duty metal construction, which is considered to be already compliant with flammability requirements and capable of withstanding the harshest environments. In addition, the metal key lock prevents unauthorized access to your important drives, and the thumb screw lock adds extra protection from impact, reducing drive tray vibration and increasing drive stability during transportation. Furthermore, the removable drive tray design allows the interchangeability between systems.
The ToughArmor MB491SKL-B supports 2.5-inch SAS and SATA hard drives or SSDs at 6Gbps transfer speeds and is backward compatible with 3Gbps drives and hosts. The MB491SKL-B dual-lock mobile rack is an ideal data storage enclosure for enterprise, industrial, in-vehicle, military, and medical applications where reliability and security are critical.
Removable Design with Maximum Protection

The removable drive tray design supports hot-swap and makes maintenance completely hassle free in the event of a hard drive failure. With a simple swap of the hard drive, your overall down time is greatly reduced which is especially useful for time sensitive projects and applications. The trays are designed to accommodate a 7 to 15mm height hard drive or SSD, creating a 2.5” hot swap bay for any standard SATA/SAS drive. While the tray is not installed to the MB491SKL-B, the Anti-Dust Flap helps prevent dust from entering the device.
The metal key lock on the tray prevents unauthorized access to your drive. The unique thumb screw design locks the metal tray into the device to minimize the drive vibration, and to prevent accidental drive tray ejection, providing the ultimate protection for your hard drives or solid-state drives.
The removable drive tray design combined with our dual layer drive security system makes the ToughArmor EX MB491SKL-B a great mobile rack for mobile servers and military grade systems.
Packed with Features

The front of the ToughArmor EX includes a status LED when the drive is powered on, off and accessed. Active Power Technology (APT) allows the status LED to be on only when a hard drive is inserted into the enclosure. We have also included drive ID plugs so users with multiple MB491SKL-B units in their system can give each drive tray a unique ID number.
A Military-grade Durability

Challenging environments require gear that can take a beating and withstand harsh conditions for as long as the situation demands. It takes more than your average SSD/HDD mobile rack enclosure to meet these requirements. The MB491SKL-B 2.5" drive enclosure complies with military standards *MIL-STD-810H 516.8 (Shock) and 514.8 (Vibration) and is built with the full-metal construction for flammability requirements, making MB491SKL-B suitable for even the most demanding applications.

*Note: MIL-STD-810H is the set of methods and test procedures that have governed environmental engineering considerations for aerospace and defense applications for over 60 years.

Customizable ICY DOCK Drive Enclosures: Tailored to Meet TAA & UL Certification Standards and More!

At ICY DOCK, we understand the paramount importance of adhering to various industry and safety standards. While our standard products are already crafted with the highest quality in mind, we also provide our customers with the option to customize ICY DOCK drive enclosures and mobile racks to meet their specific certification requirements. This includes standards such as TAA and UL to military-grade tests.

Our dedicated team is fully prepared to adjust product materials and designs to ensure complete compliance. Furthermore, we offer comprehensive guidance to our clients throughout the certification process. Our goal is to not only meet precise specifications but also ensure that our products successfully pass stringent tests. Below, you'll find a detailed table listing all the optional certifications that can be tested with our customizable solutions.

Optional Certifications Available for ToughArmor EX MB491SKL-B
TAA	Trade Agreements Act Compliance
UL	Safety Standard Certification
UL94	Flammability of Plastic Materials
FCC	Federal Communications Commission Compliance
Wide Temperature	MIL-STD-810H - Method 501.7 & 502.7
Vibration Test	MIL-STD-810H, Method 514.8, Procedure I (Resistance to vibrations)
Functional Shock	MIL-STD-810H, Method 516.8- Procedure I (Protection against shocks)
*IEC 60529 (IPX5)	Protection against water jets

*The drive mobile rack enclosure needs to have a customized front water-resistant panel added to pass the IEC 60529 (IPX5) certification. Water resistance refers to preventing water or dust from entering the enclosure through the front panel when the product is installed in the chassis, rather than making the entire enclosure water-resistant.

Customizing ICY DOCK products for specific certifications involves fees for the creation of the certificates, including necessary testing. Please note that some certificates may require recurring fees to remain valid. For more details and inquiries,please contact us at tech@icydock.com

FAQ

Q: Does MB491SKL-B support the new SATA 3.3 / SAS 3.0 Power Disable feature (PWDIS)?

A: The MB491SKL-B does not support the SATA 3.3 / SAS 3.0 PWDIS feature. If you install the SATA/SAS HDD/SSD with PWDIS in MB491SKL-B , the drive will not spin, and the system won't detect the drive. See the list below for known SATA/SAS HDD/SSD with the PWDIS feature.

Known SATA/SAS HDD/SSD with Power Disable Feature (PWDIS)

While we recommend to avoid using the SATA/SAS HDD/SSD with PWDIS, you can use the methods below to disable the PWDIS feature physically if you already purchased the drive:

Method 1 – Using the Molex to SATA adapter or cable to disconnect the power to Pin 3 of the SATA power connector.


Molex to SATA Adapter		Molex to SATA Cable

Method 2 – Placing Kapton tape on Pin 1-3 of the SATA/SAS power connector to isolate the 3.3V power, as shown below.

Please contact tech@icydock.com if the problem persists.

Q: I feel that the drive tray's upper and lower metal spring is stuck when inserting the drive tray. What should I do?

A: Remove the drive tray from the enclosure and reinsert the tray without putting excessive pressure on the metal mesh sheet in front of the tray. Excessive force on the front metal mesh sheet may bend the top and bottom metal spring, causing difficulties when inserting the drive tray. Therefore, please do not forcingly insert the drive tray when this happens as it may cause damage to the metal spring.

Please DO NOT put excessive pressure on the metal mesh sheet as shown
