Huawei ETP power systems and R4850 rectifier modules

Huawei's ETP embedded power systems are the DC power platform behind most Huawei-built base station sites, and buyers running Huawei radio equipment generally want a matching ETP system rather than a mixed-vendor power solution. The recurring enquiry is a rectifier module — R4850G2 is the module most commonly requested — to add capacity or replace one that has failed, or a full ETP48200 cabinet for a new site build.

How to read these part numbers

ETP model numbers give the system's rated capacity — ETP48200 is a 200A-class system, ETP4830 is a compact 30A-class unit, ETP48150 sits between them. The suffix letters (A1, C5A1, C5B4) mark hardware and control-board revisions; a later revision generally accepts more rectifier types but confirm compatibility with your existing modules before mixing revisions in one shelf. R4850-series rectifier modules are numbered by generation — G1, G2, N2 — each a step up in efficiency and density; a newer-generation module will usually work in an older shelf, but the reverse is not guaranteed.

Ordering notes

Give the exact ETP system model and revision letter, and for rectifier modules confirm the generation your shelf currently uses before mixing generations. State whether you need the SMU02B management unit or only rectifier hardware. Condition is stated per quotation — new, new-surplus or refurbished — and where a destination does not admit used network equipment (Algeria is the usual example) we quote new. Hardware only: software licensing remains between the buyer and the manufacturer. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will say so on the quotation.

Lifecycle and availability

R4850G2 and R4850N2 modules and current ETP48200 revisions remain in production and are sourced new; earlier ETP4830/ETP4890 systems and R4815/R4830 modules are increasingly surplus-only as sites migrate to higher-capacity shelves. CRS PLUS is an independent broker and is not an authorised Huawei partner.

Equipment condition

New — factory-sealed, supplied through the manufacturer's authorised channel or an authorised distributor, with full manufacturer warranty.

New surplus — unused factory stock, original packaging where available, sourced from decommissioned projects or distributor inventory. Manufacturer warranty may have lapsed; CRS PLUS warranty applies.

Refurbished / tested — previously deployed equipment, cleaned, firmware-checked and functionally tested against the manufacturer's specification before shipment. CRS PLUS warranty applies.

Condition is confirmed in writing on every quotation before you commit to an order.

Warranty

Warranty terms vary by item, by condition and by the supplier the equipment is sourced from. They are stated in writing on the quotation, per line item, before you commit to an order.

Where equipment is supplied new through an authorised channel, the manufacturer's warranty applies and is passed to you.

Send us the part numbers you need and we will confirm warranty terms alongside availability, condition, lead time and price.

Frequently asked questions

In most ETP48200 shelves, yes, since Huawei has kept the mechanical and connector envelope consistent across R4850 generations — but confirm your shelf's control-board firmware with us, since some older boards do not correctly report the newer module's telemetry.
