Sierra 10 NextGen UPS for Ultra-Compact Long-Backup Telecom and Network Loads
Sierra 10 NextGen UPS is a compact rack-based backup solution for small critical loads such as routers, switches, access nodes, radio equipment, and other telecom or network devices that must stay online far longer than a conventional small UPS usually allows. Built on a modular 48 Vdc / 230 Vac platform in a 1U, 19-inch subrack format, it delivers very high power density and scalable autonomy in extremely limited cabinet space, while also allowing complementary 48 Vdc loads to be fed where combined AC and DC protection is useful.
In Astrec-integrated LFP configurations, Sierra 10 is particularly well suited to telecom cabinets, edge-network locations, and other small technical spaces where the requirement is not just short ride-through, but many hours or even days of runtime from a very small footprint.
Sierra 10 NextGen UPS – Key features and advantages
Designed for very long-backup protection of small telecom and network loads where rack space is scarce, runtime requirements are measured in hours or days, and low lifetime cost matters as much as backup performance.
Ultra-compact 1U power core
The Sierra 10 subrack delivers up to 6 kW in just 1U, making it a strong fit for cabinets where conventional long-backup UPS systems would take too much space.
Very long backup from LFP batteries
With Astrec-integrated LFP battery systems, Sierra 10 can be configured for many hours or even days of autonomy for small critical loads.
UPS with comple-mentary DC output
The platform can protect the main AC load while also feeding complementary 48 Vdc loads where the site architecture benefits from combined AC and DC backup.
Low TCO over long service life
The combination of high efficiency, modular serviceability, and LFP battery longevity can reduce maintenance, replacement frequency, and overall lifetime cost.
System format and deployment options
Compare the two main Sierra 10 NextGen UPS formats: a compact IEC-socket solution for smaller loads, and a higher-capacity cabinet architecture with external monitoring and 230 V distribution for larger long-backup deployments.
Compact UPS system up to 3 kW with IEC sockets
This format is designed for smaller telecom and network loads that need very long backup time from the smallest possible footprint. With built-in IEC sockets, the system is easy to deploy for routers, switches, access equipment, and other light critical AC loads directly inside a standard rack. At the same time, screw terminals at the rear allow the system to be connected to an external PDU when a more AC sockets are needed.
In practical long-backup design, a three-module system paired with four 100 Ah LFP batteries can support a modest AC load such as 400 VA for at least 48 hours, while still allowing full recharge from empty in about 6 hours. That creates a very different operating model from a conventional small UPS. In some sites, it can remove the need for a permanently installed generator altogether. In longer regional outages, it can also support a rotating temporary-generator strategy, where one mobile generator is used across multiple sites instead of building generator infrastructure into every location. The result is a compact long-autonomy solution with very low space demand and potentially much lower total site cost.
Scalable UPS system up to 5 kW with external Inview S and 230 V PDU
For higher small-site loads, Sierra 10 can be built as cabinet-based long-backup solutions with external monitoring and AC distribution. This keeps the power core compact while allowing a more structured layout for monitoring, maintenance, and 230 V load distribution.
Typical solution formats include:
- 4 kW system – 1U Sierra 10 power core with an additional 1U PDU
- 5 kW system – 1U Sierra 10 power core with 2U Inview S and 1U external PDU
This approach is well suited to telecom and network cabinets where the load is above the basic socket-version range, but the goal is still a very compact long-backup system with clear monitoring and organized AC distribution. It also gives more flexibility for battery sizing, cabinet layout, and service access in larger LFP-based autonomy designs.

Inview Slot monitoring and supervision
Sierra 10 can be equipped with integrated monitoring and communication, giving the system a practical control layer for alarms, status visibility, and site-level supervision in compact telecom and network cabinets.
In long-backup small-site UPS systems, monitoring is part of the architecture, not an accessory. It helps operators supervise battery-backed power locally, track system status clearly, and integrate the solution into wider site monitoring where needed.
Sierra 10 48/230 power module
The Sierra 10 solution is built around compact hot-swappable 48 Vdc / 230 Vac converter modules that combine high power density with modular serviceability in a 1U rack format.
This module architecture is what makes the platform suitable for very compact long-backup UPS solutions. Capacity can be built modularly, the power core remains small, and the system can protect AC loads while also allowing complementary 48 Vdc output where the application benefits from it.
Efore 2U LFP battery integration
The Efore IBUE-48100 battery is a particularly strong fit for Sierra 10 long-backup systems because it combines 48 V, 100 Ah capacity with a compact 19-inch 2U format. That makes it easier to build very long-autonomy solutions without consuming excessive cabinet space. It also supports parallel use of up to 16 battery units, giving substantial flexibility for larger runtime targets.
For this type of UPS solution, the low 2U height is a major practical advantage. The battery uses LFP chemistry, provides 4.8 kWh nominal energy, and is specified for long service life in standby-oriented backup use, with calendar life up to 15 years. The ability to use up to 16 battery units in parallel makes it practical to scale the solution from compact cabinet-level backup to much longer autonomy designs while keeping the system architecture clean and modular.
