A truly open power platform
Designed for large-scale OCP ORV3 deployments, the OCtoPower M-CRPS 48V combines open standards with advanced management capabilities for maximum flexibility and resilience.
Open Power
Architecture
M-CRPS & CRPS compatible, broader supplier choice, reduced vendor lock-in.
Multi-Vendor M-CRPS Operation
Mix modules from multiple manufacturers in the same shelf for maximum sourcing flexibility.
Flexible
Redundancy
N, N+1 or N+N modes, within a single shelf or across multiple shelves.
Smart Power Management
Per-module PMBus monitoring via Web UI, REST API and scripting (Python, Node.js).
Out-of-Band Management
Dedicated Ethernet & SSH, isolated from the power path for secure remote access.
Simplified Lifecycle
Hot-swap M-CRPS modules, easier replacement, sparing and long-term maintenance.
CRPS & M-CRPS
Compatible Power Shelf
By adopting the M-CRPS and CRPS standard, OCtoPower gives access to a broader range of PSU suppliers.
Customers can select qualified manufacturers according to availability, pricing or project requirements.
This reduces dependency on a single vendor, improves supply-chain resilience and can help shorten lead times. It also creates better price competition for large-scale deployments.
Centralized Supervision
& Remote Administration
An embedded management controller provides centralized supervision of the power shelf and its six M-CRPS modules. Power status, temperature and PSU operating data can be monitored individually through PMBus.
Secure Web UI (HTTPS) and REST API access simplify remote administration and integrate seamlessly with existing data-center management systems. Over-the-air firmware updates are supported.
