Tripp Lite SR24UB Server Rack Enclosure Review

The SR24UB's strengths are practical ones that show up on delivery day and every time you open the door.

It arrives built

The cabinet ships fully assembled. You fit the casters and levelers and start loading rails, with no flat-pack frame to square up and no bag of bolts for the panels. For a one-person install in a closet or back office, that removes the worst afternoon of the job.

Depth adjusts in quarter-inch steps

Front and rear pairs of vertical rails with square holes move from 3 to 32.5 inches in quarter-inch increments, and each rack space is numbered. You can set the rear rails to the exact depth of your deepest chassis and keep the front rails where your patch panels and switches want them.

It carries a real load

The rating is 1,000 lb stationary and rolling load. A loaded 24U of switches, patch panels and mid-depth servers sits well inside that, and the casters are rated for the same figure as the frame.

Access control without a locksmith

The front door locks and is reversible, so you can hang it to open the way your room allows. The side panels lock and lift off, which gives you open side access for cabling and for reaching the rear of equipment without walking around the cabinet.

Air moves through it

The front door and side panels are perforated, and the top and bottom panels carry vents so warm air leaves the top while cool air is drawn in at the bottom. The cabinet accepts standard user-supplied case fans, such as the Tripp Lite SRFANWM, if convection alone isn't enough for your gear.

Cabling goes in and out cleanly

Cable routing ports at the top and bottom let you bring power and network runs in from above or below the floor, which is how most closets and small IT rooms are wired.

Compliance and long support

The SR24UB meets all requirements for PCI DSS compliance, carries a 5-year limited warranty, and spare parts stay available for 5 years. For a small business that has to answer a security questionnaire, that paperwork matters as much as the steel.

Counter height is the point

At 24U the cabinet stands around counter height, so the top works as a surface and the whole thing fits a closet or a small room where a full-height cabinet would dominate the space or not go in at all.

The 32.5-inch maximum mounting depth answers most of the buying question. Measure the deepest chassis you plan to install, add clearance for rear cabling and for a PDU mounted at the back, and compare the total to 32.5 inches. Mid-depth 2U servers fit with a few inches to spare. Full-depth 4U storage servers and deep GPU chassis do not, and a rear-mounted PDU eats the margin on a server that only just fits.

There are no toolless vertical or 0U PDU mounting rails. A vertical power strip has to be worked around with your own brackets or strapping rather than clipped into place, which is the complaint one owner on a forum reports about this cabinet.

No cable management brackets or vertical managers come with it. Plan on your own velcro, hooks or managers if you want the rear to stay tidy.

There is a single rear door, so the cabinet needs clear space behind it for the door to swing open. Leave room for that when you lay out the room.

Security is tamper-evident rather than vault-grade. The doors and side panels lock, but the top panel is not listed as locking, and the steel is light enough that the cabinet deters and records access rather than defeating a determined intruder.

There is no airflow containment and no filtered door. In a dusty or industrial space, a filtered variant of the same cabinet is the better fit.

Delivery condition is the recurring owner complaint, with owners on forums reporting units arriving dented or with bent panels. Inspect the SR24UB on the pallet before you sign, and note any damage on the delivery receipt.

At 136.7 lb and delivered on a pallet, the SR24UB arrives by freight rather than as a parcel drop.
