APC AR3357 NetShelter SX 48U

Pre-installed full-enclosure height rear accessory channels
Integrated and adjustable rear accessory channel provides zero U mounting locations for toolless accessories. Each channel has two mounting bays to support a combination of up to four accessories such as PDUs and vertical cable organizers. 1070mm (42in), 825mm (32 in), and deep enclosures and networking enclosures include two channels. 1200mm (48in) deep enclosures include four channels. Channels are pre-installed at the factory in the rear of the enclosure but can be moved to other locations of the enclosure along the side brace to resituate cable management where it is needed most.

Adjustable mounting rails with captive hardware and rapid alignment
The vertical mounting rails can be adjusted in 1/4 in (6.4 mm) increments covering virtually any mounting requirement for IT equipment. Easy alignment feature integrated into the enclosure mounting rail and side brace for quick alignment verification without the use of tools to verify alignment. U positions are numbered front and back for rapid installation of equipment.

Split rear doors
Split rear doors improve access and serviceability to rear of rack mounted equipment. The split rear doors help to maximize floor space. Only 11 inches (279 mm) of clearance is required behind the enclosures to allow for door swing.

Low-profile castors and adjustable leveling feet from underneath or above
Enclosures are shipped standard with both leveling feet and castors. Leveling feet can be quickly adjusted through the use of a screwdriver or drill, eliminating the need to reach underneath with a wrench.

Integrated joining hardware with multiple width enclosure alignment
Enclosures include pre-installed joining hardware to join enclosures in a row and provide additional stability to the enclosure. The pre-installed joining hardware includes holes for joining to an adjacent enclosure at 600mm centers or 24in centers depending upon the floor layout.

Special packaging options for shipping rack with equipment mounted
Enclosures with shock packaging are standard enclosures with provisions in the packaging design and enclosure assembly for shipping the enclosures with equipment mounted inside. Check apc.com for enclosure size options and availability.

Enclosure assemble-to-order (ATO) options capable
The Enclosure ATO (Assemble-to-Order) options provide a level of customization for enclosure customers beyond the standard enclosure models. This customization is limited to the assembly of the enclosure itself and does not include additional enclosure mounted components. For example, the enclosure can be assembled without sides, doors, or without sides and doors. Check apc.com for enclosure size options and availability.

Designed for enhanced structural stability
A proven frame design, heavy-gauge mounting rails, and heavy-duty casters provide for 3000 lb (1364 kg) static (levelling feet) and 2250 lb (1023 kg) dynamic (castor) load ratings. Enclosures have been tested and approved to be combined with proper bolt down accessories to meet various seismic requirements. Check apc.com for product documentation for specific requirements.
