About the iMcV-Switch
The iMcV-Switch is a 5-port Ethernet module that allows the user to increase the port
density and service area of Ethernet networks. The store and forward switch function
allows the user to extend Ethernet service to locations a total of 100 meters from the
Ethernet source. All RJ-45 ports Auto Negotiate 10/100BaseT, full/half duplex, and
automatically configure for MDI or MDIX operation. Each port allows a maximum
frame size of up to 1916 bytes, with support for Flow Control and priority queuing.
Each SFP or fixed fiber port supports 100 Mbps FDX; the fiber is available in a variety
of SM and MM types, including SSF.
Priority Queuing
The iMcV-Switch supports two levels of priority queuing at the egress of every port.
All frames with high priority will egress the port ahead of low priority frames at a 10:1
ratio. Priority is determined, first, through VLAN Tag priority. If no VLAN Tag is
available then the DiffServ (ToS) bits are used. The VLAN Tag priority is based on a 3
bit PRI word where the base priority is set to “4”. Values of 4 or greater have high
priority.
Flow Control
Flow Control is based on the outcome of the Auto Negotiate function. If Flow
Control is enabled then a port will stop transmitting frames when a PAUSE frames is
received. When the internal buffers become congested the unit will send PAUSE
frames to all congested ports. Frames will be dropped if no internal buffer space is
available at ingress.
Installing the iMcV-Switch
The iMcV-Switch is a media converter module that provides 5-port 10/100 Auto
Negotiating Ethernet ports. The module can be installed in any iMediaChassis,
MediaChassis or IE-MediaChassis series.
Managed Modules
In order to manage an iMcV-Switch, an SNMP agent must be present in the chassis.
To manage the module, first install the module into the chassis. After installing IMC
Network’s free SNMP software, iView², port status per port can be monitored. There
is no port configuration; the Graphical User Interface (GUI) provides LED status
information only. SFP’s with DDMI will not offer an SFP Table through iView².

Unmanaged Modules
The iMcV-Switch is an unmanaged 5-port 10/100 module; there are no DIP Switch
settings to configure. If installed in an unmanaged chassis, the LEDs will indicate the
status of each port.
Port LEDs
The ports on the iMcV-Switch include diagnostic LEDs that indicate unique
information about the port functionality and status.

Fiber Optic Cleaning Guidelines
Fiber Optic transmitters and receivers are extremely susceptible to contamination by
particles of dirt or dust, which can obstruct the optic path and cause performance
degradation. Good system performance requires clean optics and connector ferrules.
1. Use fiber patch cords (or connectors, if you terminate your own fiber) only from
a reputable supplier; low-quality components can cause many hard-to-diagnose
problems in an installation.
2. Dust caps are installed at IMC Networks to ensure factory-clean optical devices.
These protective caps should not be removed until the moment of connecting
the fiber cable to the device. Should it be necessary to disconnect the fiber
device, reinstall the protective dust caps.
3. Store spare caps in a dust-free environment such as a sealed plastic bag or box
so that when reinstalled they do not introduce any contamination to the optics.
4. If you suspect that the optics have been contaminated, alternate between
blasting with clean, dry, compressed air and flushing with methanol to remove
particles of dirt.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in modules or
stand alone units, containing electronic components. Always observe the following
precautions when installing or handling these kinds of products
1. Do not remove unit from its protective packaging until ready to install.
2. Wear an ESD wrist grounding strap before handling any module or component.
If the wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.
3. Hold the units by the edges; do not touch the electronic components or gold
connectors.
4. After removal, always place the boards on a grounded, static-free surface, ESD
pad or in a proper ESD bag. Do not slide the modules or stand alone units over
any surface.
WARNING! Integrated circuits and fiber optic components are
extremely susceptible to electrostatic discharge damage. Do not
handle these components directly unless you are a qualified service
technician and use tools and techniques that conform to accepted
industry practices.
