Rackmount.IT RM-FB-T5: 19-inch rack kit for AVM FRITZ!Box 6590, 6591 and 6690 Cable
2U · 19-inchSignal WhiteFront-facing portsPower supply fixed in rack
The Rackmount.IT RM-FB-T5 is a custom 19-inch rack mount kit for FRITZ!Box 6590 Cable, 6591 Cable, 6690 Cable that places the router in 2U of rack space with its connections brought to the front, for IT teams and installers who want a desktop router to sit properly in a network cabinet.
Desktop routers are built to stand on a shelf, with ports at the back and a loose external power adapter. In a cabinet that usually means a device lying on a shelf and cables you cannot reach. This kit replaces that: the router slides into a tray made for its exact shape, retainers hold it in place, the included cables link its ports to keystones on the front plate, and the power supply is fixed to the rack. Rackmount.IT quotes an assembly time of under three minutes.
Before you order: This kit fits only the models Rackmount.IT lists: FRITZ!Box 6590 Cable, 6591 Cable, 6690 Cable. It is not a universal shelf, so check the exact model name on the label of your device. The FRITZ!Box 6660 and 6670 Cable are different housings — they use RM-FB-T3 or RM-FB-T7.
What's in the Box
- 1 x Rackmount.IT RM-FB-T5 rack kit, 2U, Signal White
- Retainers that hold the router in the tray
- Keystones on the front plate plus the cables that connect them to the device ports
- Fixing for the external power supply inside the rack
- Not included: the router itself, its power adapter and rack screws or cage nuts (use the set that came with your cabinet)
What It Means in Practice
- Patch cables plug into the front keystones, so you never reach behind the router to add or move a connection.
- The power adapter is fixed in the rack, so a pulled cable or a cleaning session cannot switch the router off by accident.
- It uses 2U (88.4 mm high) at standard 19-inch width and is only 216 mm deep, so it suits shallow wall cabinets as well as full-depth racks.
- Replacing the router later is quick: release the retainers, unplug the short cables and slide it out.
- At 2U it takes two rack units, because the 6590/6591/6690 are tall upright devices.
What Will Not Work
- Models that are not on the list, even from the same product family: the tray is shaped for specific housings. The 6660 and 6670 Cable models are not on the list.
- Mixed or unlisted desktop equipment: for that use a standard fixed or cantilever 19-inch shelf.
- It adds no ports, PoE, cooling or power; the router's own connections are only extended to the front.
Key Features
Custom-fit tray
Shaped for the listed router housings, so the device sits firmly without shelves, straps or cable ties.
Front-facing connections
The included cables run from the device ports to keystones on the front plate, so all patching is done from the front of the rack.
Power supply fixed in the rack
The external adapter is secured inside the kit, which prevents accidental power loss when cables are moved.

Frequently Asked Questions
Does the kit include the router?
No. The kit is only the rack mount; the router and its power adapter are ordered separately and fitted into the tray.
Do I need a deep rack?
No. The kit is 216 mm deep, so it fits most wall-mount cabinets as well as standard server racks. You only need 2U of free space at the front rails.
Singular Expert Insight · Buyer's Guide
The 6590, 6591 and 6690 Cable are tall upright routers that never sit well on a shelf. The RM-FB-T5 lays them into a 2U tray with front connections, which is the cleanest way to put a cable-modem router into a business cabinet. Browse more mounting parts in our
rack accessories range.
✓ Buy it if your cable router is a FRITZ!Box 6590, 6591 or 6690 and it has to move into a 19-inch cabinet.
✕ Skip it if you have a 6660 or 6670 Cable, or a DSL/fibre FRITZ!Box — those use other RM-FB kits.
→ Also consider RM-FB-T7 for the FRITZ!Box 6660 Cable V3, 6670 Cable and 7590 AX.
