Installation
This chapter gives step-by-step installation instructions for the Converter.
Selecting a Site for the Equipment
As with any electric device, you should place the equipment where it will not be
subjected to extreme temperatures, humidity, or electromagnetic interference.
Specifically, the site you select should meet the following requirements:
 The ambient temperature should be between 0 to 50 degrees Celsius (32 and 122
degrees Fahrenheit).
 The relative humidity should be less than 95 percent, non-condensing.
 Surrounding electrical devices should not exceed the electromagnetic field (RFC)
standards for IEC 801-3, Level 2 (3V/M) field strength.
 Make sure that the equipment receives adequate ventilation. Do not block the
ventilation holes of the equipment.
 The power outlet should be within 1.8 meters of the product.
Connecting to Power
This Converter is a plug-and-play device.
Connect the supplied AC to DC power adapter to the receptacle at the back of the
converter.
Attach the plug into a standard AC outlet.
Installing in a Chassis
The Converter is designed to fit into any of the expansion slots on an EtherWAN
rackmount chassis.
 Unscrew the carrier from the desired expansion slot on the chassis.
 Fit the converter onto the carrier.
 When the converter is completely seated onto the carrier, insert the carrier to the
guide rails of the expansion slot.
 Carefully slide in the carrier until it is fully and firmly fit the chassis.
 Fasten the carrier to the chassis by the screws.
NOTE: Never insert any converter into the chassis directly without using the
supplied carriers. The carriers allow secure and consistent placement of the
converters into the chassis’ backplane without causing any damage.

Converter Configuration
Jumbo Frame (9K): The media converter can pass packets up to 9KB in size if this
function is enabled.
Link Transparent: If the Link Transparent (Link-Fault-Pass-Through) is enabled, the
Link Loss Carry Forward will be active.
Link Loss Carry Forward: If this function is enabled, when the UTP port link down, the
fiber port will be forced link down. And the fiber will be resumed when UTP port link up.
Forward CRC Error Frame: The CRC error packets will be passed if this function is
enabled. Otherwise the CRC error packets will be dropped.
Forward Pause Frame: The media converter will forward pause frame and regard it as
a normal packet if this function is enabled.
Management Packet High Priority: Need to reset media converter then this function
will take effect. All management packets will be allocated to high priority queue to
guarantee bandwidth when Management Packet High Priority is enabled. Media
converter will enable QoS and four queues and set queue 3 as strict priority if this
function is enabled. All management packets such as 802.3ah OAM and SNMP packets
will be in queue 3 to guarantee bandwidth.
Broadcast Storm Filter: If this function is enabled, when too many broadcast packets
arrive in a period time, the broadcast packets will be dropped.
Multicast Storm Filter: If this function is enabled, when too many multicast packets
arrive in a period time, the multicast packets will be dropped.
Unknown DA Unicast Storm Filter: If this function is enabled, when too many unknown
DA unicast packets arrive in a period time, the unknown DA unicast packets will be
dropped.

VLAN Per Port Setting:
Egress Link Type:
Replace Tag: The media converter will remove VLAN tags from packets then add new
tags to them. The inserted tag is the ingress port’s “Default tag”, which is indexed by port
“Port based VLAN index”. This is a replacement processing for tagged packets and an
insertion for untagged packets.
Remove Tag: The media converter will remove VLAN tags from packets if they are
tagged when these packets are output. The media converter will not modify packets
received without tags.
Add Tag: The media converter will add VLAN tags to packets if they are not tagged
when these packets are output on this port. The media converter will not add tags to
packets already tagged. The inserted tag is the ingress port’s “Default tag”, which is
indexed by port’s “Port based VLAN index”.
Don’t Touch Tag: Do not insert or remove VLAN tags to/from packet which is output on
this port.
Port VLAN Entry: Select Port based VLAN index. The number refers to the VLAN table
entry index, not VID.
Ingress Filter: Click “Ingress Filter” drop-down menu to choose “Disable” or “Enable”
from the “Ingress Filter” drop-down list to disable or enable VLAN ingress filter.
Apply: Click “Apply” button when you have finished VLAN Group setting.
Please make sure the VLAN port entry can go through CPU port.

Remote Setting
802.3ah Functions
This converter supports IEEE 802.3ah, an OAM (Operations, Administration and
Maintenance) protocol that provides a uniform way to detect, confirm, and isolate faults.
OAM only works point-to-point over the fiber link. In addition to standard 802.3ah
functions like loop back and dying gasp, the EL2321 implements OAM to provide
complete provisioning of the remote fiber connected converter, without using Layer 3 IP
protocol. The 802.3ah auto-discovery function uses OAM PDUs, sent periodically, to
detect the presence of another 802.3ah device in the link.
802.3ah Configuration
Use this section to configure OAM settings.
802.3ah Function: Choose “Disable” or “Enable” to disable or enable 802.3ah function.
802.3ah Mode: This field is used when configuring an OAM pair. One unit of the pair is
set to ‘active’, and the other set to ‘passive’. In most situations, the remote converter is
the passive one.
Remote Loopback: In order to perform remote loopback test, this option must be
enabled in both converters. Choose “Disable” or “Enable” to disable or enable remote
loopback.
Apply: Click “Apply” button to save settings.
Refresh: If you have made changes to the configuration settings, click “Refresh” button
to show the Discovery Status and the Fiber Port Status, displayed in the window
below.
