Industrial Redundant Managed Ethernet Media Converter with 2 Ports
1 x 10/100/1000BaseT(X) Port, 1 x 1000M SFP Port
These parameters are displayed:
■
Link – Indicates if the link is up or down.
■
Speed
–
Sets the port speed and duplex mode using auto-negotiation or manual selection.
The following options are supported:
◇
Disabled - Disables the interface. You can disable an interface due to abnormal behavior
(e.g., excessive collisions), and then renewable it after the problem has been resolved. You
may also disable an interface for security reasons.
◇
Auto - Enables auto-negotiation. When using auto-negotiation, the optimal settings will be
negotiated between the link partners based on their advertised capabilities.
◇
1Gbps FDX - Supports 1 Gbps full-duplex operation
◇
100Mbps FDX - Supports 100 Mbps full-duplex operation
◇
100Mbps HDX - Supports 100 Mbps half-duplex operation
◇
10Mbps FDX - Supports 10 Mbps full-duplex operation
◇
10Mbps HDX - Supports 10 Mbps half-duplex operation
(Default: Auto negotiation enabled; Advertised capabilities for RJ-45: 1000BASE-T - 10half,
10full, 100half, 100full, 1000full; SFP: 1000BASE-SX/LX/LH - 1000full)
NOTE: The 1000BASE-T standard does not support forced mode. Auto negotiation should always
be used to establish a connection over any 1000BASE-T port or trunk. If not used, the success of
the link process cannot be guaranteed when connecting to other types of switches.
■
Flow Control
–
Flow control can eliminate frame loss by
“
blocking
”
traffic from end stations
or segments connected directly to the switch when its buffers fill. When enabled, back pressure
is used for half duplex operation and IEEE 802.3-2005 (formally IEEE 802.3x) for full duplex
operation. (Default: Disabled)
When auto-negotiation is used, this parameter indicates the flow
control capability advertised to the link partner. When the speed and duplex mode are manually
set, the Current Rx field indicates whether pause frames are obeyed by this port, and the
Current Tx field indicates if pause frames are transmitted from this port.
Avoid using flow control on a port connected to a hub unless it is actually required to solve a
problem. Otherwise back pressure jamming signals may degrade overall performance for the
segment attached to the hub.
■
Maximum Frame Size
–
Sets the maximum transfer unit for traffic crossing the switch. Packets
exceeding the maximum frame size are dropped. (Range: 9600-1518 bytes; Default: 9600 bytes)
■
Excessive Collision Mode
–
Sets the response to take when excessive transmit collisions are
detected on a port.
