Huawei PISB Overview
The Huawei PISB (H901PISB) is an AC power board for OLTs (like MA5800-X2), featuring robust power management with AC input (110V/220V), 600W output, and lead-acid battery backup, offering features like input/output protection, power monitoring, battery management, and temperature alarms, ensuring reliable, uninterrupted service for network equipment in telecom deployments.
Product Features
- Power Input: Accepts 1 channel of 110V AC or 220V AC.
- Backup Power: Supports connection to an external lead-acid battery for uninterrupted power.
- Output: Rated at 600W, supplying power to the main OLT chassis.
- Protection: Includes over-current, over-voltage, short-circuit, and over-temperature protection for both input and output.
- Monitoring: Provides input power monitoring, temperature monitoring with high-temperature alarms, and battery management.
- Management: The integrated monitoring unit offers comprehensive power system and battery management.
Application Scenarios
A leading telecom operator in Japan deployed PISB uplink boards with MA5800-X15 OLTs to support its 10G symmetric broadband rollout in Tokyo, covering 80,000 high-end households and 10,000 enterprises. Each PISB’s 4 10GE SFP+ ports aggregated traffic from XGS-PON/hybrid PON service boards, connecting OLTs to the core network via 10Gbps fiber links. The L3 dynamic routing capability optimized traffic distribution across multiple core nodes, while hot-swappable design minimized maintenance downtime. With 40 PISB boards deployed, the operator achieved a total uplink capacity of 1.6Tbps, meeting peak traffic demands for 8K video streaming, cloud gaming, and enterprise cloud collaboration services.

FAQ
Q: Which OLT models is the Huawei PISB board compatible with?
A: It is a dedicated AC power board for the Huawei MA5800-X2 and EA5800-X2 OLTs. It is incompatible with other MA5800 models (e.g., X7/X15/X17) due to mismatched slot sizes—those models require PILA DC power boards instead.
Q: What input voltage does it support?
A: Dual voltage (110V/220V AC), auto-adaptive—no manual switching needed.
Q: What is the after-sales service period?
A: We provide a one-year warranty and technical support.
Q: Is the Huawei PISB a genuine product?
A: Absolutely. MF-Telecom sources 100% authentic Huawei equipment with traceable serial numbers and quality certification.
Q: What is the output power?
A: The rated output is 600W, which provides stable power supply for the OLT subrack.
