Power Over Ethernet
( PSE )
|
Performs the Power Sourcing Equipment ( PSE ) function on 1 or 2 UTP ports for IEEE 802.3bt compliant devices.
All models support Type 1 ( PoE ), Type 2 ( PoE+ ), Type 3 (Hi-PoE) and Type 4 (Hi-PoE) PD gear
|
|
Advanced Power Management
|
- Enable/Disable PSE power by UTP port
- Single or Dual PD signature detection
- Over-Current Protection
- PD power classification detection ( Class 0 )
|
|
PD Power Reset
|
Ideal for remotely resetting equipment, this configurable function performs a momentary power reset to the attached Powered Device (PD). When enabled, the media converter will, upon loss of fiber RX, turn off PSE output power supplied to the PD device for 2 seconds then turn the power back on and leave it on until such time that another fiber RX link is lost (after it was re-established). When disabled, a loss of fiber RX has no effect on PSE power to the PD device(s).

Powered Device Support
|
Fully Compliant with IEEE 802.3bt Type 3 and 4 PSE and compliant support for Type 1, 2, 3, and 4 PDs
Support Single-Signature and Dual-Signature PD connections
|
|
Multiport Configurations
|
- 2 port: 1x 10/100/1000Base-T and 1x SFP fiber slot
- 3 port: 1x 10/100/1000Base-T and 2x SFP fiber slots
- 4 port: 2x 10/100/1000Base-T and 2x SFP fiber slots
|
|
Fiber Redundancy
|
When enabled on dual fiber models, the media converter treats Fiber 1 as the primary and if the link fails, the fiber link is switched over to fiber 2 within 50ms.
|
|
Redundant Primary Fiber
|
If the “Fiber Redundancy” feature is also enabled, the primary fiber 1 link is continuously monitored and if is restored for at least 6 seconds, the link will be switched back from the secondary fiber 2 port to the primary fiber 1 port.
|
|
Power Strain Relief strap
|
Included with all models, a strain relief strap is provided to ensure a solid and secure power connection to the media converter. Ideal for areas that may be exposed to vibration.
|
|
SFP Speed Sensing
|
Automatically detects whether a Gigabit or Fast Ethernet fiber SFP has been inserted and adjusts accordingly.
|
|
Auto-Negotiation (802.3u)
|
The media converter supports auto negotiation. The 1000Base-X fiber interface negotiates according to 802.3 clause 37. The 10/100/1000Base-T negotiates according to 802.3 clause 28 and 40. The 1000Base-X will link up with its partner after the highest common denominator (HCD) is reached and the copper has linked up with its partner. The 1000Base-X will continue to cycle through negotiation transmitting a remote fault of offline (provided this is enabled through the switch setting) until the copper is linked up and the HCDs match.
The media converter supports auto-negotiation of full duplex, half duplex, remote fault, full duplex pause, asymmetric pause and Auto MDI-X.
|
|
Auto-MDIX
|
Auto-MDIX (automatic medium-dependant interface crossover) detects the signaling on the copper Ethernet interface to determine the type of cable connected (straight-through or crossover) and automatically configures the connection when enabled. The media converter can also correct for wires swapped within a pair.
The media converter will adjust for up to 120ns of delay skew between the 1000Base-T pairs.
|
|
Smart Link Pass-Through
|
When the Link Mode switch is placed into Smart Link Pass-Through mode, the copper Ethernet port will reflect the state of the 1000Base-X media converter port. This feature can be used whether fiber auto-negotiation is enabled or disabled.
|
|
Fiber Fault Alert
|
With Fiber Fault Alert the state of the 1000Base-X receiver is passed to the 1000Base-X transmitter. This provides fault notification to the partner device attached to the 1000Base-X interface of the media converter. If the 1000Base-X transmitter is off as a result of this fault it will be turned on periodically to allow the condition to clear should the partner device on the 1000Base-X be using a similar technique. This eliminates the possibility of lockouts that occur with some media converters. Applies only when fiber auto-negotiation is disabled.
|
|
Pause (IEEE 802.3xy)
|
Pause signaling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed. The media converter supports pause negotiation on the 10/100/1000Base-T connection and 1000Base-X fiber connection.
- With Autoneg on the device will advertise sym and asymmetric pause
- With Autoneg off – Pause receive and send will be disabled
