150 W redundant capacity – Provides backup or supplemental DC power to compatible Enterasys stackable switches, helping avoid service interruption.
Seamless failover behavior – In most cases the RPS takes over automatically if the switch’s internal PSU drops out, minimizing packet loss and phone reboots.
PoE continuity support – On PoE-capable models, the unit typically helps sustain PoE during primary power issues, keeping phones and APs online.
Simple hookup – Uses a dedicated RPS DC cable to the switch; AC input via standard IEC mains makes it easy to deploy in any rack or shelf.
Status at a glance – Front LED indicators (AC OK / DC OK / Fault) make quick checks and remote-hands guidance much easier.
Flexible placement – Desktop or 19-inch rack shelf mounting; suitable for wiring closets where space is tight and airflow matters.
| Brand / Model | ENTERASYS STK-RPS-150PS |
| HS Code | 8504.40 (Static converters / power supplies) |
| Power Requirements | 100–240 VAC, 50/60 Hz input; up to 150 W DC output to supported switches |
| Operating Temperature | 0 to 40 °C (typical indoor telecom environment) |
| Signal Input/Output Types | AC input via IEC 60320 C14; DC output via dedicated Enterasys RPS connector/cable to switch |
| Communication Interfaces | None (power-only module; no data interfaces) |
| Installation Method | Desktop or 19-inch rack shelf placement; connect RPS DC cable to supported switch RPS port |
This module fits best in enterprise wiring closets, campus networks, healthcare floors, education buildings, and manufacturing cells where downtime is costly. Typical scenarios include keeping VoIP phones powered during an internal PSU failure, avoiding AP drops in lecture halls, or stabilizing legacy SecureStack access switches while a maintenance window is arranged.
Reliability – Acts as a safety net for the switch PSU, helping prevent unplanned outages and PoE loss.
Compatibility – Built for Enterasys stackable/edge families; in many cases it’s a drop-in addition using the correct RPS cable kit.
Cost Efficiency – Extends the usable life of installed switches and reduces emergency replacement costs.
Operational Continuity – Helpful for change management: schedule PSU or switch swaps without affecting users.
Technical Support – We can help verify cable compatibility and share field tips for wiring closets with tight airflow.
Environment – Install in a 19-inch cabinet or stable shelf with front-to-back airflow; avoid blocked vents and excessive dust.
Power – Use a conditioned 100–240 VAC feed; many teams place the RPS on a UPS while leaving the switch on mains for added resilience.
Cabling – Connect the dedicated Enterasys RPS DC cable firmly to the switch RPS port; secure cables to avoid strain or accidental pull-outs.
Safety – De-energize before servicing; observe ESD precautions around the switch and connectors.
Routine Checks – Monthly LED check (AC OK / DC OK); dust the vents; test failover during a maintenance window to confirm behavior.
CE and UL safety compliance typical for enterprise power modules
RoHS compliant build in many production runs
Manufactured under ISO 9001 quality systems (vendor-level)
Warranty: 365 days (replacement or repair as per our policy)
Enterasys RPS DC Cable – Required to connect STK-RPS-150PS to the target switch; the exact cable varies by switch family (e.g., SecureStack C-series, B-series). We can help confirm the correct kit.
1U Universal Rack Shelf – For neat mounting near the switch, with cable tie-down points for strain relief.
UPS (Line-Interactive or Online) – Typically used to keep the RPS powered through mains disturbances.
Field note from a campus customer: “We added the STK-RPS-150PS to our most critical closet switches. When an internal PSU failed, phones stayed up and classes never noticed. That one save was worth the extra hardware.”
