Caution: this product is heavy, at least two (2) qualified people should perform the
assembly procedure. Care must also be taken while moving or positioning the
equipment.
After the cabinet has been assembled, adjust the leveling feet for greater stability.
When lowered correctly, the four leveling feet should support the full weight of the rack.
Use extreme caution when unpacking or removing the product parts from the boxes to
avoid damaging or misplacing of parts.
Do not exceed the recommended load capacity and the maximum weight supported by
the enclosure, as specified by the manufacturer’s specifications. Failure to comply will
void the warranty of this product.
Avoid rolling the cabinet on floors with uneven or rough surfaces to prevent casters
from getting stuck in gaps or otherwise being unnecessarily damaged.
When rolling the cabinet on casters, push the cabinet from the front or rear only, to
prevent the structure from tipping on its side.
Caution: use the recommended tools to avoid damaging the parts.
CABINET TIPPING HAZARD: ensure that the cabinet is properly stabilized and
steady by extending the leveling feet after it is placed in its permanent location before
any equipment is installed.
1. Introduction
Thank you for purchasing the semi-knocked down [SKD) floor cabinet from Nexxt
Solutions. Each floor unit is housed in lockable heavy-gauge metal enclosure designed to
house any rack-mounted components, such as server and storage units, modular
network or voice switches, routers, telecommunication systems and IT equipment. Its
split rear door design easily accommodates to any telecommunications room layout, by
minimizing the space required for access behind the cabinet. Our floor cabinets provide
more space for networking equipment, including the easy integration of rack PDUs and
high-density cable managers. Built to EIA rack standards with square punched mounting
holes, the equipment can be quickly attached inside the enclosure for data center or
computer room applications. Enhanced cooling capabilities are made possible by the
integration of a fan tray assembly. Product available in 600mm wide configuration, with
27, 32, 37, 42 and 47 rack spaces.
Main features
• 1764lb (800kg) maximum load capacity
• Frame construction reinforced with steel, specially made to support heavy weight
• Superior management system, with top and bottom access to cables and PDUs
• Lockable access to front and rear doors, as well as side panels
• Standard square-punched mounting rails for faster component loading
• The front door can turn 245 degrees and the rear door can be opened up to 245
degrees
• High-density mesh back doors provide outstanding ventilation to avoid overheating
• Its vertical PDU/cable management rail adds versatility for power and cable
distribution inside the enclosure
• Each unit sits on four casters, for ease of deployment and mobility
• Adjustable leveling feet for added stability
• EIA-compliant mounting rail system can be easily adjusted for equipment varying
depths
• U-rack units are numbered front and back for easy equipment integration
• Powder coat finish prevents damage caused by rust and other external factors

number of square holes on the beam from the front and rear ends
as needed, and insert two M6 cage nuts in each opening, with the
tabs facing inward.
2. Repeat this procedure until the first twelve (12) cage nuts are
installed on the left side.

number of rack units stamped from high (top) to low (bottom) on
each column.
Note: make sure that both ends (top and bottom) of the rail are
placed at the same level. In addition, the row of numbers on each
vertical rail must be facing each other, on the front and rear
sections of the unit.
5. Proceed to insert the M6 phillips-head screws and plastic
washers from the inside through the vertical mounting rails and into
the cage nut installed in each horizontal beam.
6. Repeat steps 1 through 5 for the right side.
Note: fully tighten the screws only after each pair of screws has
been inserted.
