Power Over Ethernet
( PSE ) |
Performs the Power Sourcing
Equipment ( PSE ) function on 1 or 2 UTP ports for IEEE 802.3af (15.4
watts PoE) and IEEE 802.3at ( up to 30 watts PoE+ ) compliant devices.
Available in PoE and PoE+ models
PoE+ models support both Type 1 ( PoE ) and Type 2 ( PoE+ ) PD gear |
| Advanced Power Management |
- Enable/Disable PSE power by UTP port
- PD signature detection
- Over-Current Protection
- PD power classification detection ( Class 0,1,2,3,4 )
|
| 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 |
Support is included for a broad range of PD ( Powered Devices )
- IEEE Standard PoE/PoE+ ( Alternative A and B )
- Legacy High Capacitance PDs
- Legacy VoIP phones and Wireless Access Points
|
| Multiport Configurations |
- 2 port – 1 UTP and 1 fiber ( fixed fiber or SFP slot )
- 3 port - 1 UTP and 2 SFP fiber slots or 2 UTP and 1 fiber ( fixed fiber or SFP slot )
- 4 port - 2 UTP and 2 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
|

| Jumbo Packets |
Transparent to jumbo packets up to 10KB. |
| VLAN |
Transparent to VLAN tagged packets. |
| Remote Loopback |
Capable of performing a loopback on the 1000Base-X fiber interface. |
