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, a monitoring unit that has stopped reporting, or a full ETP48200 subrack for a new site build. This page lists the R48-series rectifier modules from 870W to 6kW, the ETP and TP48 power systems they fit and the SMU and PMU monitoring units, with Huawei part numbers where they are published.
How to read these part numbers
Huawei rectifier names give voltage and current class: R4850 is a 48V, 50A-class (3000W) module, R4875 is 75A-class (4000W), R4830 is 30A-class and R4815 15A-class. The suffix marks the variant: G modules are the high-efficiency line (about 96%, with G6 higher), N modules the standard-efficiency line (about 94%), and S modules the super-high-efficiency line (about 98%); the number is the generation. R4850N2 is the standard-efficiency counterpart of the R4850G2, not a newer model. The eight-character code (for example 02310HBJ) is Huawei's BOM number and is the most reliable identifier on the module label. ETP system names give the capacity class (ETP48200 is 200A-class) and the suffix (C5A1, C5B4) marks hardware and input variants.

Ordering notes
Give the Huawei BOM number from the module label where possible, or the exact model and generation, and the ETP system model and revision letter it goes into. ETP48200-C5A1 and C5B4 subracks take up to four R4850G2 or R4850N2 modules with an SMU02B; ETP48400 systems take R4875G1 or R4850G5 modules with an SMU02C. State whether the monitoring unit is needed 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, R4850N2, R4875G1 / G5 and current ETP48200 and ETP48400 revisions remain in production and are sourced new; R4850G1 (2U), R4815 and R4830 modules and the ETP4830 / ETP4890 systems are increasingly surplus-only as sites migrate to higher-capacity shelves. Monitoring units have moved from SMU01B to SMU01C on small systems and from SMU02B to SMU02C on 5U and cabinet systems. CRS PLUS is an independent broker and is not a qualified Huawei partner.
Equipment condition
New — factory-sealed, supplied through the manufacturer's own channel or a qualified 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 the manufacturer's own 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.
Questions
Frequently asked questions
Can an R4850N2 replace an R4850G2 in the same shelf?
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.
What is the difference between ETP48200 and ETP4890?
Capacity class. ETP48200 is a 200A-class 5U system for larger sites; ETP4890 is a compact 2U unit for smaller cabinets. They are not interchangeable and use different rectifier module counts.
Do you supply the SMU02B monitoring unit separately?
Yes, as a standalone spare when only the management/monitoring unit has failed and the rectifier modules themselves are fine.
