Rackmount 1U fibre enclosure

The Black Box Corporation JPM427A-R2 is a 1U rackmount fibre enclosure designed for patch panel applications. It fits a standard 19 inch rack and provides three adapter slots for flexible connectivity. The unit includes a pull-out tray for easier access to installed modules. It is built for professional network infrastructure deployments.

Three-slot adapter limitation

The enclosure accepts a maximum of three adapter modules, which defines the port density available in a single 1U space. Installers must plan fibre counts around this fixed slot limit. The non-locking design allows quick module changes but does not secure adapters against accidental removal. Cable management relies on the supplied ties, organisers and distribution rings.

TAA-compliant for government use

This model carries Trade Agreements Act compliance and a GSA schedule reference, making it eligible for federal procurement. The 45-day supply indication supports contractual delivery requirements. Buyers without TAA mandates do not gain a functional advantage from this certification.

商品問答

Should I pick the 1U 19-inch three-slot version or a different height?

The unit is a 1U rack-mount shelf that fits a standard 19-inch rack and provides three adapter slots; choose it when you need exactly one rack unit of height.

What does the 10.8-inch depth mean once the shelf is installed in my rack?

At 10.8 inches deep the shelf sits well within most standard racks, leaving ample rear clearance for cable routing and the included pull-out tray.

How do the 10-32 and 12-24 cuphead screws work with my rack rails?

Both 10-32 and 12-24 cuphead screws are supplied so you can mount the shelf on either thread pattern without extra hardware.
