IT teams deploying dense 19-inch equipment

The 45U height and adjustable mounting rails suit installations that need maximum vertical density within a 750 mm footprint. Side panels and keyed-alike locks help secure multi-rack rows in shared data halls. Buyers who need a shallower cabinet for limited floor depth or a lower U count for lighter workloads should consider other form factors.

45U capacity in a 750 mm x 1200 mm frame

The 45U internal height is the single specification that determines whether this enclosure fits your current and planned rack-mount inventory. Verify that your servers, switches and PDUs do not exceed the 1048 mm maximum mounting depth before committing to this frame.

Questions about this item

How much floor space does the 750 mm wide by 1200 mm deep rack need?

The enclosure footprint is 750 mm wide and 1200 mm deep, so allow at least that much clear floor area plus room for door swing and side-panel removal.

Which mounting-rail depth range does the AR3355 support for 19-inch equipment?

The rails adjust from a minimum of 262 mm to a maximum of 1048 mm, so set the rail depth to match your deepest server before tightening the cage nuts.

When should the pre-installed casters be swapped for the included leveling feet?

Roll the rack into position on the casters, then lower the leveling feet to take the weight and lock the enclosure in place for a stable, vibration-free installation.
