Host & Equipment Compatibility
| Compatible Host / Equipment | Compatible BBU/Baseband: Huawei BBU3900/3910/5900 host matching the board generation. Compatible RRU/RRH/AAU: Connected RRU/AAU family depends on board capability, RAT and software. System modules: Host chassis, UMPT control, UBBP/WBBP/LBBP processing, UPEU/UPBA power/support. Cabinets/subracks: 19-inch rack or Huawei cabinet with suitable backplane and -48 V DC distribution. Antennas/AAU: Determined by connected radio. |
|---|
| Required Companion Equipment | Compatible BBU chassis/backplane, UMPT control, UBBP/WBBP/LBBP processing as applicable, power entry/support and cooling. |
|---|
| Related Radios / BBU | Connected RRU/AAU family depends on board capability, RAT and software |
|---|
| Compatible Cabinet / Subrack | 19-inch rack or Huawei cabinet with suitable backplane and -48 V DC distribution |
|---|
| Slot / Form Factor | 19-inch or vendor-specific form factor; verify exact chassis |
|---|
Interfaces & Power
| Interfaces & Connectors | RF: No RF connectors; Fronthaul/transport: no CPRI; data exchange through the BBU backplane; Power: -48 V DC / power monitoring through chassis connectors; Management/synchronization: dry-contact alarm/monitoring and revision-dependent RJ45 or multipin harness; Other: backplane connector |
|---|
| Transport / Optical Interfaces | No CPRI; data exchange through the BBU backplane |
|---|
| Power Source | Powered by BBU chassis/backplane from -48 V DC |
|---|
| Power Connector Type | Board-to-board / backplane power connector; no separate external DC connector on the UPBA/support board |
|---|
| Required Power / Internal Cable | No separate power cable to the board is required |
|---|
| Power Consumption | Estimated maximum 90 W |
|---|
Installation & Thermal Role
| Cooling / Thermal Role | Host subrack/chassis airflow; filler panels and slot rules apply |
|---|
| Installation Location | Inside host chassis/subrack |
|---|
| Mounting Method | Plug-in slot, backplane or internal rack position |
|---|
| Mounting Kit / Hardware | No separate external mounting kit; use host chassis guide rails, ejector handles, captive screws and filler panels |
|---|
| Known Mounting Kit PNs | No standalone mounting-kit PN; host chassis hardware applies |
|---|
| Fasteners / Fixings | Captive faceplate screws, board ejector handles, guide rails and slot filler panels. Do not improvise external mounting. |
|---|
| Cables & Connections | Host backplane connection; optical/Ethernet patch cord where the module exposes front ports; internal power through backplane; alarm/synchronization cable only when the specific module provides that interface |
|---|
| Dimensions | 45 × 400 × 280 mm |
|---|
| Weight | 3.0 kg net |
|---|
| Operating Temperature | -5 to +55 °C |
|---|
Identity & Verification
| Data / Compatibility Status | Mixed / revision check; Board/module installation confirmed at host-platform level |
|---|
| Battery / Shipping | No large battery installed in the listed BBU chassis/support item; The listed BBU chassis/support item normally ships without the external lithium battery. Check packaging and BOM for a separately supplied DBU battery |
