12-slot media converter chassis

The Tripp Lite N785CH12 is a 3U rack-mountable chassis that houses and powers up to 12 select media converters. It supports SC, ST and SFP module types for copper-to-fiber or copper-to-copper network installations. The unit includes an AC power supply and hardware for desktop, wall or rack installation.

Dual AC power supply with rear cooling

A redundant power design accepts primary and backup supplies with one 75 W AC adapter included. The adapter operates on 90-240 V at 50/60 Hz input and delivers 12 V at 6.5 A output through a NEMA 5-15P plug. Rear-mounted fans maintain airflow while front LEDs provide immediate status visibility for troubleshooting.

Flexible mounting with trigger guard safety

Included brackets allow 3U rack, wall or desktop deployment without extra parts. An on/off trigger guard prevents accidental power switching during maintenance. The chassis measures 11.420 x 16.930 x 5.240 inches and works exclusively with select N784-H and N785-H converter models.

Questions about this item

How do I install the N785CH12 in a 3U rack, and which step is often missed?

Use the included mounting brackets to secure the 11.420 x 16.930 x 5.240 inch chassis in a 3U rack space, then connect the AC adapter to a 90-240V 50/60Hz circuit; the step often missed is engaging the on/off trigger guard to prevent accidental power cycling.

What maintenance will the N785CH12 need over time?

The rear cooling fans should be checked periodically for dust buildup to maintain airflow across the 12 media converter slots, and the glass-tube fuse in the included N785-CH75W-AC supply may need replacement if it blows.

What limit appears first when the chassis runs fully loaded for extended periods?

With all 12 slots populated, the 12V 6.5A output of the single included AC supply becomes the limiting factor; adding the optional redundant supply removes that constraint.
