Description
Product Overview
The Enterasys STK-RPS-150PS P0973BP is a redundant power supply module designed for Enterasys managed Ethernet switch platforms requiring external backup power support. Installed as part of the SecureStack RPS architecture, this unit provides an auxiliary DC power source that helps maintain switch operation if the internal primary power supply experiences a fault. The Enterasys STK-RPS-150PS P0973BP is commonly used with Enterasys stackable switch families where network availability is a critical requirement.
The Enterasys STK-RPS-150PS P0973BP operates as a dedicated power subsystem rather than a network processing device. It does not manage Ethernet traffic, VLAN configuration, or switching functions; instead, it supplies regulated DC power through the dedicated RPS interface to supported switches. The module accepts a wide AC input range and provides a 12VDC output suitable for compatible Enterasys network equipment.
Within industrial automation networks, reliable power distribution is often as important as communication performance. The Enterasys STK-RPS-150PS P0973BP can support Ethernet infrastructure used for PLC, DCS, SCADA, and industrial monitoring networks by reducing the risk of switch shutdown caused by a single power supply failure. It is normally installed in applications where network interruptions could affect operator access, engineering communication, or supervisory data exchange.
To be completely transparent, compatibility should be verified before replacement. Engineers should confirm the exact switch model, RPS cable type, chassis arrangement, and existing power configuration. The STK-RPS-150PS series uses a dedicated connector system, and incorrect connection methods may damage network hardware.
For maintenance teams supporting installed Enterasys infrastructure, the Enterasys STK-RPS-150PS P0973BP provides a practical method to preserve existing network designs without replacing the complete switch assembly. Inspection of power indicators, output voltage, connector condition, and switch recognition should be completed before returning the network equipment to service.

Frequently Asked Questions (FAQ)
1. What is the Enterasys used for?
The Enterasys is an external redundant power supply module used to provide backup DC power for compatible Enterasys Ethernet switches. It supports continued switch operation when the primary internal power source fails.
2. Can I hot-swap the Enterasys ?
The replacement method depends on the connected switch model and system design.
Recommended procedure:
- Verify the switch supports RPS operation.
- Confirm the correct RPS cable is installed.
- Check the current power status.
- Replace according to the switch maintenance procedure.
- Confirm power and fault indicators after installation.
The dedicated RPS connection should be treated carefully because it is designed specifically for compatible equipment.
3. Does the Enterasys support firmware v3.1?
No firmware management is normally associated with this module. The is a power hardware component.
Compatibility depends on:
- Supported switch model
- RPS interface design
- Power requirements
- Installed network hardware revision
4. Will replacing the Enterasys erase my switch configuration?
No. The RPS module does not store switch operating software, VLAN settings, or network configuration.
After replacement, technicians should verify:
- Switch power status
- RPS fault indicators
- Network link status
- Existing switch configuration retention
5. How can I verify a New Surplus Enterasys ?
Recommended inspection steps:
- Confirm model marking: .
- Verify part number .
- Inspect enclosure and connectors.
- Check input/output electrical ratings.
- Test with a compatible switch before field deployment.
6. Which Enterasys switches are compatible with ?
Compatibility depends on the specific switch family and RPS connector design. The module is associated with Enterasys stackable switch platforms including selected SecureStack families. Engineers should verify the exact switch model before installation.
7. Is the Enterasys suitable for industrial network replacement projects?
Yes, when maintaining existing Enterasys-based Ethernet infrastructure. For replacement planning, engineers should evaluate switch lifecycle status, network architecture, communication requirements, and available spare hardware before changing the power design.
