Product Introduction
The Emerson SS6048R2P3 DeltaV SIS Smart Switch provides Ethernet connectivity for safety-related control-system devices. Its base configuration includes eight 10/100BASE-TX copper ports and two Gigabit Ethernet uplinks. Additional connectivity is available through SS6049-series expansion modules, supporting copper Ethernet, multimode fiber, single-mode fiber, and SFP-based interfaces.
Unlike a general-purpose industrial Ethernet switch, the SS6048 series is designed specifically for Emerson DeltaV SIS networks. Its dedicated software and network behavior support the safety-system architecture without requiring conventional manual switch configuration. The switch is intended for use within the Local Safety Network and Global Safety Network, where supported DeltaV SIS components exchange safety-related data.
The R2P3 version is supplied with the European power-cord configuration. For system expansion, the switch supports up to two additional 8-port media modules, allowing a maximum configuration of 26 Ethernet ports. The expansion modules are hot-swappable according to the Emerson documentation.

Application Scenarios & Field Pitfalls
Typical applications
- Emerson DeltaV SIS Local Safety Network.
- DeltaV SIS Global Safety Network.
- Safety controller and CSLS network connectivity.
- Distributed safety-system communication.
- Fiber-optic connections between safety network cabinets.
- Industrial process safety infrastructure in oil, gas, chemical, and power facilities.
Important engineering checks
- SIS compatibility: Use only supported DeltaV SIS Smart Switch hardware in the designated SIS network. A conventional DeltaV Smart Switch is not an interchangeable substitute.
- Port configuration: The base unit has eight copper device ports and two Gigabit uplinks. Do not confuse this with an eight-port total configuration.
- Expansion modules: Confirm the exact SS6049 module type before installation. Copper, multimode, single-mode, and SFP versions have different optical and electrical interfaces.
- Fiber compatibility: Verify fiber type, wavelength, transceiver specifications, connector type, and link budget. Supported distances vary by optical configuration.
- Power supply: Confirm 100–240 VAC input and inspect the supplied European power cord. Do not assume the switch accepts a 24 VDC supply.
- Safety network software: Emerson documentation specifies Smart Switch software release 4.2.14 or later for GSN use. Confirm the installed software version against the actual DeltaV SIS release.
- Unused ports: Emerson documentation specifies that unused ports must be blocked using the designated security plugs.

Procurement and Quality Control
For purchasing, specify the complete part number:
Emerson SS6048R2P3 – DeltaV SIS Smart 8-Port Switch, European Power Cord
Before accepting a replacement, verify:
- Complete model number and serial number.
- Original European power-cord configuration.
- Eight copper ports and two Gigabit uplinks.
- Expansion-slot condition and module compatibility.
- Ethernet link operation on all installed ports.
- Alarm-contact operation.
- Software version and DeltaV SIS compatibility.
- Physical condition of the rack mounting brackets and connectors.
- Test results using a compatible DeltaV SIS network configuration.
Replacement recommendation: Match the SS6048R2P3 exactly when replacing an existing unit. Do not substitute a similarly named DeltaV Smart Switch or general-purpose Ethernet switch in a safety network. A successful power-on test alone does not establish correct SIS network operation.
