Middle Atlantic Rack Mount Equalizer

1. Introduction

The Middle Atlantic VSA-1626 is an adjustable depth telescoping rack shelf designed for secure mounting of equipment within standard 19-inch equipment racks. Constructed from durable 16-gauge steel with a black finish, this shelf provides robust support and features for efficient cable management and superior cooling. Its adjustable depth allows for versatile installation in various rack configurations.

Key features include a fully vented design for optimal airflow, mounting to both front and rear rack rails for stability, and multiple tie points for organized cable routing. The shelf can also be inverted to increase the usable depth within an enclosure.

2. Safety Information

Please read and understand all safety instructions before installing or operating the VSA-1626 rack shelf. Failure to do so may result in injury or damage to equipment.

• Weight Capacity: Do not exceed the maximum weight capacity of 500 lbs (226.8 kg). Distribute weight evenly on the shelf.
• Installation: Ensure the rack shelf is securely mounted to both front and rear rack rails using appropriate hardware. Improper installation can lead to instability and equipment damage.
• Ventilation: The shelf is vented to promote airflow. Do not obstruct ventilation openings.
• Handling: Use caution when handling the shelf due to its weight and sharp edges.

3. Package Contents

Verify that all components are present before beginning installation:

• 1 x Adjustable Telescoping Rack Shelf (VSA-1626)
• (Mounting hardware sold separately, typically included with rack or equipment)

4. Setup and Installation

The VSA-1626 rack shelf is designed for easy installation into standard 19-inch equipment racks. It requires mounting to both the front and rear rack rails for optimal stability and weight distribution.

1. Determine Mounting Position: Identify the desired height and depth within your equipment rack for the shelf.
2. Adjust Depth: Extend or retract the telescoping sections to match the depth of your rack's front and rear rails. The adjustable depth range is 16" to 26". For racks deeper than 26", the shelf can be mounted upside down to increase usable depth up to 44".
3. Secure Front Mounting: Align the front mounting ears of the shelf with the desired rack unit (RU) holes on the front rack rails. Secure using appropriate rack screws (not included).
4. Secure Rear Mounting: Extend the rear mounting brackets to align with the corresponding holes on the rear rack rails. Secure using appropriate rack screws. Ensure both front and rear connections are tight and secure.
5. Verify Stability: Gently test the shelf's stability before placing any equipment on it. It should be level and firmly attached to the rack.

5. Operation and Usage

Once installed, the VSA-1626 rack shelf provides a stable platform for various rack-mountable or non-rack-mountable equipment.

• Equipment Placement: Carefully place equipment onto the shelf, ensuring weight is distributed as evenly as possible.
• Cable Management: Utilize the several 1.25-inch tie points located along the sides and rear of the shelf to secure cables using cable ties or hook-and-loop fasteners. This helps maintain a tidy rack and improves airflow.
• Ventilation: The fully vented design allows for passive cooling of equipment placed on the shelf. Ensure that the rack environment itself has adequate airflow.

6. Maintenance

The Middle Atlantic VSA-1626 rack shelf requires minimal maintenance to ensure long-term performance.

• Cleaning: Periodically wipe the shelf with a soft, dry cloth to remove dust and debris. For stubborn marks, a slightly damp cloth with mild detergent can be used, followed by drying. Avoid abrasive cleaners or solvents.
• Inspection: Regularly inspect the mounting screws and connections to ensure they remain tight. Check for any signs of wear, bending, or damage to the shelf.

7. Troubleshooting

This section addresses common concerns you might encounter with the VSA-1626 rack shelf.

• Shelf is not stable after installation:
  • Ensure all mounting screws (front and rear) are securely tightened.
  • Verify that the shelf is correctly aligned with the rack rails and not binding.
  • Confirm that the rack itself is stable and properly assembled.
• Equipment does not fit on the shelf:
  • Check the dimensions of your equipment against the shelf's usable area.
  • Ensure the shelf's depth is correctly adjusted for your rack. Remember it can be mounted upside down for increased depth.
