R250D-E Overview
R250D-E room wiring starts with GE0 and GE1 having different power roles
Label the uplink as GE0/PoE_IN and the powered downstream connection as GE1/PoE_OUT. Both carry 10/100/1000M Ethernet, while GE2, GE3 and GE4 are documented for wired data. The E hardware chapter therefore answers a different outlet requirement from the base R250D, whose port list contains GE0/PoE_IN and one GE1 data connection. Keep the E suffix and exact numbered port on the procurement and installation schedules.
Match the optional DC source to 48 volts
Huawei names the socket DC 48V and specifies 48 V ±5% in the R250D-E power table. A 12 V adapter from another wall-plate RU is not the documented source for this model. The same table accepts IEEE 802.3af/at PoE input, but it does not establish a universal downstream power allowance under each input mode. Confirm the chosen PSE or central-AP source and the intended downstream load before selecting how the room is powered.
The quoted RU consumption does not cover all attached loads
The 11.5 W value explicitly excludes output power from USB and PoE_OUT. Build the installation budget from the RU reference plus the actual peripheral requirements, rather than treating that reference as the total source budget. The cited hardware chapter assigns no fixed PoE-output wattage here; it also says actual maximum consumption depends on local rules. Acceptance should include the intended downstream device operating on GE1, not merely an idle RU powered through GE0.
USB storage and transparent cabling are separate functions
The USB2.0 connection is described for a flash drive or other storage device extending AP storage. The RJ45 Pass Through port is described for transparent transmission of a network or phone cable. These interfaces are not additional switched GE sockets, and the cable pass-through description is not a promise of a telephone gateway. Check storage-device compatibility and the passive cable route against the manufacturer documentation and the room design.
Allow for the E enclosure when replacing a base R250D
The R250D-E reference measures 36 × 86 × 140 mm in height, width and depth and weighs 0.26 kg. The separately documented R250D is 26 × 86 × 120 mm and 0.2 kg, with 10.1 W consumption. Their shared characteristics identify an 86 mm plate and junction-box installation, but the larger E enclosure still needs a physical fit check. The reference image is manufacturer artwork for R250D-E; final supplied revision and fixing accessories should be checked at quotation.
Commission the radio through the intended central AP
The shared R250D/R250D-E chapter identifies centrally managed remote units with IEEE 802.11a/b/g/n/ac/ac Wave 2 on 2.4 and 5 GHz. R250D-E has a built-in omnidirectional antenna, with 4 dBi at 2.4 GHz and 5 dBi at 5 GHz. Reference limits are up to 256 users, dependent on the environment, and 16 VAPs per radio. Confirm central-device and software support and test room coverage; these references do not establish arbitrary standalone operation or guaranteed client capacity.
Check enclosure conditions and registration together
The operating reference is 0°C to +40°C at −60 to 1800 m, with an upper-temperature reduction of 1°C per 300 m above 1800 m through 5000 m. Humidity is 5–95% non-condensing. Huawei places the single indicator inside the panel and distinguishes startup, normal running, software upgrade and registration failure states. Use the indicator together with actual central-AP registration and wired-client tests, rather than accepting the unit solely because its panel light comes on.
