Operation Manual

FCC Radio Frequency Interference Statement

This equipment has been tested and found to comply with the limits for a Class B computing device, pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial

environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the

instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to

cause harmful interference in which the user will be required to correct the interference at his own expense.

Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.

The use of non-shielded I/O cables may not guarantee compliance with FCC RFI limits. This digital apparatus does not exceed the Class B

limits for radio noise emission from digital apparatus set out in the Radio Interference Regulation of the Canadian Department of

Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de classe B

prescrites dans le Règlement sur le brouillage radioélectrique publié par le ministère des Communications du Canada.

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.
