the opposite side doors can be detached and reversed.
Expansion
SX enclosures can be easily expanded upon to create complete rows of enclosures. In addition the SX can be tied into the existing VX build-outs via the appropriate baying hardware.
Door ventilation exceeds 830 in2 (5355 cm2)
Adequate ventilation is required for proper operation of today's servers. NetShelter SX Enclosures include fully perforated front and rear doors to provide ample ventilation for servers and networking equipment. The perforation pattern provides 919 square inches of open area on the front door exceeding requirements set forth by major server manufacturers. Although this ventilation pattern provides adequate cooling for most configurations air-moving accessories such as APC's Air Distribution Unit are also available to support higher heat density applications.
Rear Cable Management channels
Integrated rear cable management channels allow customers to easily route manage and access large numbers of data cables even while an enclosure is loaded with rack-mount equipment and bayed within a row.
Rear Power Distribution channels
Rear power distribution channels provide easy access to multiple receptacles occupying zero U in recessed channels . The rear power distribution channels allow APC basic metered and switched vertical rack PDU's to be installed easily in the rear without interfering with equipment or taking up valuable U space. This provides increased accessibility to receptacles and allows customers to support more power cords within the enclosure. Up to 42 5-15R receptacles can be installed in just one rear cabling channel.
Cable Access
Generous cable access holes are provided in the roof and base of the NetShelter SX to enable power and data cables to be routed into the rack either from overhead or from underneath a raised floor. The NetShelter SX enclosure offers eight cable access holes of various sizes on the roof. The eight are broken out as follows: five 60mm x 175mm two 79mm x 167mm and one 79mm x 245mm. In addition for maximum cable routing capacity the roof can be removed entirely even if cables are already installed. The base of the rack is
