Compatible Replacement & Equivalent Models
If the STK-RPS-150PS is discontinued or out of budget, the following models are commonly evaluated as replacements or equivalents. Always verify connector type and wattage before substitution:
- Enterasys STK-RPS-200PS – Higher-wattage successor; direct chassis fit for upgraded power headroom
- Cabletron Systems RPS-150 – Legacy OEM equivalent from the Cabletron era; same electrical spec
- Generic 150W Hot-Swap PSU – Third-party units with matching backplane pinout; requires compatibility verification
- Enterasys 7G4202-49 – Alternate PSU used in overlapping STK chassis generations
Contact Konmask.com for cross-reference verification before ordering a replacement.
Why Choose the Original STK-RPS-150PS
- Guaranteed chassis fit – Engineered specifically for Enterasys STK-series backplane; no adapter required
- Hot-swap capability – Replace under load without network downtime
- Validated power delivery – Precise 150W output prevents under-voltage faults on fully-loaded switch stacks
- OEM firmware compatibility – Recognized natively by Enterasys EOS/XOS management software
- Proven MTBF – Industrial-grade capacitors rated for continuous 24/7 operation
Typical Applications
- Enterprise LAN core and distribution layer switch stacks
- Campus network wiring closets requiring high-availability uptime
- Industrial Ethernet backbones in manufacturing and process control environments
- Data center top-of-rack switching with N+1 power redundancy
- Government and education networks with strict uptime SLA requirements
System Compatibility
The STK-RPS-150PS is confirmed compatible with the following Enterasys platforms:
- Enterasys Stackable Switch STK-S Series chassis
- Cabletron Systems SmartSwitch Router (SSR) stackable units
- Enterasys Matrix Series (select models – verify chassis revision)
Note: Compatibility with third-party or rebranded chassis (e.g., Extreme Networks post-acquisition variants) must be confirmed via part cross-reference. Contact our team for assistance.
Selection Guide
Use the following criteria to select the correct power supply for your Enterasys stack:
- Step 1 – Identify chassis model: Confirm your STK chassis revision (label on rear panel)
- Step 2 – Calculate power budget: Sum port PoE load + switching ASIC draw; ensure PSU wattage ≥ 120% of peak load
- Step 3 – Determine redundancy mode: 1+1 redundancy requires two PSU slots; verify your chassis supports dual PSU
- Step 4 – Choose condition: New OEM for critical uptime; certified refurbished for budget-sensitive spares inventory
- Step 5 – Confirm lead time: Contact Konmask.com for real-time stock status and expedited shipping options

Replacement & Compatibility FAQ
Q: Is the STK-RPS-150PS still in production?
A: Enterasys Networks was acquired by Extreme Networks. The STK-RPS-150PS is an end-of-life (EOL) part. Konmask.com maintains stock of new-old-stock (NOS) and certified refurbished units.
Q: Can I use a generic 150W PSU as a replacement?
A: Only if the backplane connector pinout and voltage rails match exactly. We strongly recommend using OEM or verified-compatible units to avoid chassis damage. Contact us for a validated cross-reference.
Q: Does this PSU support hot-swap replacement?
A: Yes. The STK-RPS-150PS supports live hot-swap in dual-PSU chassis configurations without requiring a network outage.
Q: What is the difference between STK-RPS-150PS and STK-RPS-200PS?
A: The 200PS variant delivers 50W additional headroom and is recommended for fully-loaded PoE stacks. Both units are physically compatible with the same STK chassis slots.
Q: Do you ship internationally?
A: Yes. We ship worldwide from China with DHL Express, FedEx, and sea freight options. Contact us for a freight quote.
