LED Operation
Each iMcV Module features diagnostic LEDs that provide information on features
and ports.
LEDs on iMcV-LIM and iMcV-PIM
The LEDs and their locations are the
same on iMcV-LIM and iMcV-PIM
Modules. The LED functions are as
follows:
•
LL
- Glows green when FX LinkLoss
is enabled.
•
LNK
- Glows green when a link is
established on the port.
•
XMT
- Blinks green when port is
transmitting data.
•
RCV
- Blinks yellow when port is
receiving data.
•
FA
* - Glows green when FiberAlert is
enabled.
*FiberAlert is not available/applicable on
single-strand versions of iMcV-LIM.
LEDs on iMcV-S2MM/S2SM/M2MM
The LED functions on iMcV-S2MM/S2SM/M2MM are as follows:
•
ENA
Glows green when port is enabled.
•
ACT
Glows yellow in normal operation, indicating that fiber is connected and
the receiver is seeing light pulses. (As these are protocol-independent
modules, there is no true “link” signal available.)

About the iMcV-Modules
iMcV Modules are SNMP-manageable and install in the modular, SNMP-
manageable iMediaChassis, iMediaCenter, and in the unmanaged MediaChassis
series. The following media conversion and fiber mode conversion iMcV
Modules are described in this manual:
•
iMcV-PIM
Ethernet module providing a single conversion between 10Base-T twisted pair
and 10Base-FL single-mode or multi-mode fiber. Each iMcV-PIM includes
one RJ-45 connector and one pair of ST or SC fiber optic connectors.
•
iMcV-LIM
Fast Ethernet module provides a single conversion between 100Base-TX
twisted pair and 100Base-FX/SX single-mode or multi-mode fiber. Each iMcV-
LIM includes one RJ-45 connector and one pair of ST or SC fiber optic
connectors (or one small form factor connector).
Also available in a single-strand fiber version, iMcV-LIM TX/SSFX allows two
wavelengths to share one fiber strand — Full-Duplex data travels on different
wavelengths (1310 nm and 1550 nm) — doubling the capacity of fiber.
Includes one RJ-45 connector and one SC fiber connector.
•
iMcV-S2MM/M2MM/S2SM
Protocol-independent modules provide a single conversion between single-
mode and multi-mode (S2MM*) fiber, 1300 nm to 1550 nm single-mode
(S2SM), or 850 nm to 1300 nm multi-mode (M2MM). Supported transmission
speeds are: 10-155 Mbps and 622- 1250 Mbps. Each module includes two
pairs of ST or SC fiber optic connectors (or small form factor connector).
Single-strand fiber versions also available.
