1.1

Features and Configuration

The IE-Giga-MiniMc provides a single conversion between 10/100/1000 Base-T
twisted pair and 1000 Base-SX/FX fiber. This device auto negotiates speed and
duplex on the copper port and the fiber is 1000Mbps, FDX. The IE-Giga-MiniMc
supports jumbo frames up to 9216 MTU.
The IE represents the unit's use as an Industrial Ethernet device, which allows for
extended temperature operation of -25°C to +85°C for DC power and -10°C to +50°C
when using the included AC adapter.
The IE-Giga-MiniMc, a fixed fiber transceiver model, provides one 10/100/1000 Mbps
Ethernet port with a RJ-45 connector and one 1000 Mbps fiber port with SC, ST, or
SFP type connector.
The IE-Giga-MiniMc can use either the included universal, external power adapter
with 100 to 240 ±10% VAC input or can be wired directly to the 7-50 VDC terminal
block (for extended temperature configuration). There is an optional IE-PowerTray/18
whereby up to 18 IE-Giga-MiniMcs can be installed.

Operations, Administration, Maintenance (OAM)

OAM is a general term used in network management and typically applied to a series
of standard protocols for installing, monitoring, and troubleshooting Metropolitan Area
Networks (MANs).
When applied to Ethernet, OAM is typically assumed to refer to the layer 2 (MAC
layer), management protocols (specifically 802.3ah and 802.1ag). Layer 2
management protocols do not need higher level transport protocols to operate, OAM
data is transferred in standard multicast Ethernet frames.
802.3ah OAM (LINK-OAM):

A point-to-point protocol designed to verify a specific link between two directly
connected devices (over copper or fiber), that support 802.3ah OAM. One
device must be configured as an active OAM device; the other as passive
(typically a core switch would be the active device; the end device passive).
802.3ah OAM provides link status, remote fault detection and the ability to
initiate a loopback circuit.
802.1ag (SERVICE-OAM):

Often referred to as Connectivity Fault Management (CFM), is an end-to-end
protocol designed to verify a specific network path between two devices that
may be in different geographical locations. CFM allows the network operator to
administer, monitor and debug the network using continuity check (a "heart
beat" message), link trace (similar to traceroot, but operating at the MAC layer)
and loopback (can be likened to a layer 2 ping).

