Configurator check against each catalogue rack, not a physical-fit certification. Depth uses the catalogue model; confirm cable clearance and your hardware revision.

Model & configuration

Published 203 × 76 × 33 mm envelope. Original white rounded enclosure reconstructed from manufacturer photos. Seven front Gigabit PoE+ ports; port 8 is the rear Gigabit PoE++ input. All eight sockets support cable connections. Fits existing hex shelf flat in 1U including deck, with only 3.25 mm total width clearance. No mount or power adapter bundled. Power profile uses switch consumption excluding PoE output; the available PoE budget depends on the input supply.

Power reference

unknown: Unknown
maximum excluding PoE output: 9 W

Manufacturer device draw: maximum 9 W on PoE input or 8 W on DC adapter, excluding PoE output. Idle is not published. PoE output budget depends on the input supply; downstream device draw must not be counted twice.
