The Juniper PWR-MX960-4100-AC-S-B is a 4100W AC power supply module engineered specifically for the MX960 Services Router chassis. This is a rear-bay, hot-insertable component built to sustain the power demands of fully-loaded MX960 systems running production workloads across carrier, enterprise, and service provider networks. For network engineers and infrastructure teams managing these routers in data centre environments, having the correct OEM power supply on hand is not optional—it is foundational to system availability and warranty integrity.

Juniper Networks designed the PWR-MX960-4100-AC-S-B to work within the MX960's multi-PSU bay architecture, which means the module slots into the chassis rear panel alongside other power supplies in an N+1 redundant configuration. This redundancy model is critical in environments where unplanned downtime carries measurable cost. A single PSU failure does not degrade service; the remaining supply continues carrying the load while operations staff arrange a replacement. The hot-swap capability means you can physically extract and install this module without shutting down the router, provided the redundant PSU is in place and powered. This is the difference between "we scheduled maintenance next Tuesday" and "we swapped the unit during the shift without a ticket."

The part number PWR-MX960-4100-AC-S-B identifies this as the 4100W variant, scaled to meet the power envelope of an 11-slot MX960 chassis with fully-populated line cards under sustained traffic load. Juniper publishes power consumption tables for different line card configurations, and infrastructure architects use these tables to calculate whether a single 4100W supply or redundant pairs are required for their specific deployment. The module integrates with Junos OS chassis management, meaning your monitoring dashboards will show real-time power consumption, efficiency metrics, and any thermal or fault events flagged by the PSU itself. This telemetry feeds directly into SNMP traps and syslog streams, so your NOC sees a power-related event the moment it occurs.

OEM components carry weight in enterprise procurement because they carry Juniper Networks support. The PWR-MX960-4100-AC-S-B ships as genuine Juniper hardware with full manufacturer backing. If a module fails under warranty, Juniper will replace it. If you install a third-party or refurbished PSU and something goes wrong downstream in the chassis, warranty coverage becomes a conversation—one you do not want to have. Network engineers and procurement teams responsible for MX960 deployments typically specify OEM PSUs for this reason alone, regardless of cost differences. Omnixon Global stocks this part as genuine Juniper inventory, which means you are getting the authentic component with full traceability and support eligibility.

In practice, the PWR-MX960-4100-AC-S-B serves mission-critical roles in carrier-grade deployments across GCC and South Asian networks. Whether you are standing up a new MX960 in a data centre, replacing a failed PSU, or building redundant capacity for an existing installation, this module is a direct replacement that requires no configuration or firmware updates. It arrives ready to install. Omnixon Global maintains stock of Juniper power supplies and components throughout the UAE and across the broader GCC region, positioned to support enterprises, AI infrastructure labs, and data centre operations that depend on Juniper routing platforms.

Power Supply Specifications and Redundancy Architecture

• Output capacity: 4100W AC power, sufficient for fully-populated 11-slot MX960 chassis with sustained line card load
• Hot-swap capable: insert and remove the module without powering down the router when N+1 redundancy is configured
• N+1 redundancy supported: multiple PSUs in the chassis provide fault tolerance; single-unit failure does not interrupt service
• Junos OS integration: real-time power telemetry, consumption monitoring, and fault alerts streamed to management interfaces and syslog
• Genuine Juniper OEM hardware with full manufacturer warranty and technical support included
• Compatible with all MX960 models and line card configurations within the published power envelope specifications
• Rear-bay form factor: module installs into the standard PSU bay without requiring chassis modifications or special cabling
