Expansion cabinet for bayed rows

The SR42UBMDEXP is a 42U mid-depth expansion rack designed to join other cabinets in a continuous row. It ships without side panels because its integrated baying tabs lock directly to adjacent enclosures. The frame accepts standard 19-inch EIA-310-E equipment up to 3000 lbs. Data-centre installers who need a single standalone cabinet should choose a model that includes side panels.

Fixed depth and rail adjustment range

The cabinet depth is 36 inches with vertical rails adjustable in quarter-inch increments from 4 to 31 inches. An easy-view depth index helps align front and rear rails consistently without repeated measuring. Equipment deeper than 31 inches cannot be mounted, and the 24-inch overall width limits cable-management accessories to those designed for 600 mm frames. No other mounting standards are supported.

Welded steel frame with lockable doors

The 186 lb welded steel body includes front and rear doors, a roof and stabilizing brackets. Square-hole cage-nut rails allow toolless 0U mounting for up to four compatible PDUs or cable managers on two vertical rails. Each rack space is numbered for quick reference. Fifty M6 cage nuts, screws and washers plus two door keys are included. Side panels must be sourced separately if the row ends are exposed.

Questions about this item

Should I choose the 42U expansion rack or the 45U model for my row layout?

The 42U expansion rack provides 42U of mounting space and is designed to bay with other cabinets using integrated tabs; the 45U model offers three additional rack units if you need more vertical capacity.

What does the 3000lb load rating mean when the rack is fully populated?

The 3000lb rating covers the combined weight of all 19-inch EIA-310-E compliant equipment installed across the 42U, supported by the adjustable front and rear rails.

How does the 19-inch EIA-310-E mounting standard limit what I can install?

The square-hole cage-nut rails accept any vendor-neutral 19-inch equipment that meets EIA-310-E, with rail depth adjustable from 4 to 31 inches in quarter-inch steps.
