The 9466-ET 10/100Mbps, Layer 2. Ethernet switch allows the

interconnection of MTL 9460-ET range networking modules via its 5

ports. It also enables an Ethernet network to cover a greater distance

using either Cat5e cable or fibre-optic for longer spans. This capability

is due to the low latency 'store and forward' mechanism integral to

the switch, which ensures that the stringent timing associated with

Ethernet is maintained.

With the 9466-ET switch each connection is effectively a 'point-to

point' network segment unlike the older generation hubs that were

simple 'dumb' repeaters. The old hubs needed to impose a limit on

overall network length to ensure proper collision detection; this limit is

overcome by the 9466-ET. Broadcast “storm” protection is also provided

to eliminate network overload due to excessive 'broadcast' & 'multicast'

packets.

The 9466-ET switch can also distribute power to compatible devices

connected to each of its five ports via the RJ45 Cat5e cables (PoEx).

This method eliminates the separate power supply cable to the device

simplifying installation and maintenance.

The 9466-ET is designed for hazardous-area mounting inside a suitable

enclosure with intrinsically safe Zone 1. ATEX and IECEx certification

and Division 1 FM USA and Canada approvals. The ATEX and IECEx

approvals cover both surface industry and mining applications.

The default mode of operation is a 5-port, unmanaged switch with auto

negotiation. However the onboard EEPROM memory can be configured

via the serial RS232/TTL port either in the safe area, using a PC, or in

the hazardous area using the 9461-ET Ethernet Gateway as its host

processor.

Programmable features such as Rate Limiting, VLAN support and

Forced Speed and Duplex settings may be configured in this way,

along with access to MIB counters etc. The 9466-ET also has Intelligent

Routing with automatic address learning, aging and migration.

It supports IEEE 802.3: 10Base-T, 100Base-TX and also MDI / MDI-X

auto crossover, for easy cascading of switches with standard cables.

The module is supplied as a DIN-rail mounting device.
