WEB OPERATION & CONFIGURATION
Configured Speed:
This pull down selects any available link speed for the given switch port. Only speeds supported by
the specific port are shown.
Possible copper port settings are:
Disabled:
Disables the switch port operation.
Auto:
Port auto negotiating speed with the link partner, selecting the highest speed that is compatible with the
link partner and negotiating the duplex mode.
10Mbps HDX:
Forces the port to 10Mbps half duplex mode.
10Mbps FDX:
Forces the port to 10Mbps full duplex mode.
100Mbps HDX:
Forces the port to 100Mbps half duplex mode.
100Mbps FDX:
Forces the port to 100Mbps full duplex mode.
1Gbps FDX
: Forces the port to 1Gbps full duplex.
Possible fiber port settings are:
Disabled:
Disables the switch port operation.
Auto:
Port auto negotiating speed with the link partner, selecting the highest speed that is compatible with the
link partner.
100Mbps FDX:
Forces the fiber port to 100Mbps full duplex mode.
1Gbps FDX
: Forces the fiber port to 1Gbps full duplex mode.
2.5Gbps FDX:
Forces the fiber port to 2.5Gbps full duplex mode.
Flow Control:
The Current Rx column indicates whether pause frames on the port are obeyed, and the Current Tx
column indicates whether pause frames on the port are transmitted. The Rx and Tx settings are determined by the
result of the last Auto-Negotiation. Check the configured column to use flow control. This setting is also related to the
setting for Configured Link Speed.
Maximum Frame Size:
Enter the maximum frame size allowed for the switch port, including FCS. This switch supports
up to 9600 byte packets.
Excessive Collision Mode:
This setting configures the port transmit collision behavior to either "Discard" (Discard
frame after 16 collisions - default) or to "Restart" (Restart backoff algorithm after 16 collisions).
Auto Laser Shutdown:
Auto Laser Shutdown (ALS) is an optical safety mechanism which will shutoff laser transmission
if the transceiver experiences a loss of receive signal. This function is disabled by default.
Link Loss Forwarding Configuration
In a simple media converter (two ports), a loss of fiber receive signal (link failure) can be used to force down the
electrical Ethernet link and vice versa. This mechanism is referred to as "Link Loss Forwarding" or "Link Fault Pass-
through".
This device is a four port L2 Ethernet switch with two fiber and two electrical Ethernet ports. With Link Loss
Forwarding mechanism, when one Ethernet port detects a link down condition, this media converter can be
programmed to logically force down any or all of the other Ethernet ports. The settings are done by checking the
