SW-700 – Ethernet Switch
1.1
SW-700 MODULE
Part Number
SW-700 - Ethernet Switch
Description
Smar SW-700 module is a Fast Ethernet Switch that provides LAN networks with 10 Base-T/100
Base-TX high-speed auto-sensing connectivity. Five ports, where one is dedicated for the Uplink will
provide access for many devices and will help to eliminate traffic congestions that cannott be well
treated by Network Hubs.
The SW-700 is also a great choice when connecting different speed networks as Ethernet and Fast
Ethernet and will also optimize finding the right path for same type of Ethernet. LED indicators for
link/activity, speed, full/half duplex and collision for each individual port and one for module power.
It can be powered by the Rack or by an external 24Vdc. Power supply redundancy circuit will
automatically switch from the user preferred supply to the other one in case of failure.
Industrial design, no internal fans and low EMC makes it a great option for automation and process
control applications.
SW-700 Auto-sensing Ethernet Switch
Operation
The SW-700 has a frame buffer composed of 1M bits of built-in memory. The address look-up table
for MAC addresses learning/searching consists of 1K direct-mapping tries.
The SW-700 uses Nway auto-negotiation to complete the UTP port connections of physical links
which conform to IEEE 802.3u specifications. IEEE 802.3x full duplex flow control is supported.
When operating in half duplex mode, a proprietary back-pressure algorithm is implemented to
prevent traditional hub devices from partitioning due to excessive collisions.

SW-700 - Instruction Operation Manual
1.2
The SW-700 supports non-blocking wire speed forwarding rates and special designs to resolve
head-of-line blocking problems and channel-capture problems. A broadcast storm filtering function is
also provided for abnormal broadcast traffic issues.
Auto-polarity is implemented to correct the detected reverse polarity of RXIP/RXIN signal pairs.
The SW-700 implements power saving mode on per port basis. A port automatically enters power
saving mode 10 seconds after the cable is disconnected from it.
Address Search, Learning and Aging:
The SW-700 contains a full 1K of look-up table entries and uses a direct-mapping scheme to
achieve address search and learning.
By extracting the least 10 bits of a destination MAC address to index the 1K-entry look-up table, the
SW-700 can decide where the packet goes. If the searching result indexes to an empty entry, the
packet is broadcast to all other ports. On the other hand, the SW-700 extracts the least 10 bits of a
source MAC address to index the 1K-entry look-up table. If the result indexes to an empty entry, it
records the source MAC address and related switching information. If the result leads to an
occupied entry with different switching information, it updates the entry with the new information.
This is referred to as 'learning'. The look-up engine will update time stamp information of an entry
whenever the corresponding source MAC address appears. If the time information is not updated for
a period of time, the entry will be removed, referred to as the aging process. The maximum aging
time for the SW-700 is approximately 300 seconds, and the minimum aging time is approximately
200 seconds.
Installation
The SW-700 may be installed in a rack, powered by the rack bus or alone with a 24 Vdc external
power supply, using the DF9 rack to mount it on the DIN rail. For both cases, when the module is
powered, the green LED for power indication will light.
Installation of the module into the DF9 individual support
SW-700 module can also be installed into the DF9 individual support using 24 Vdc external power
supply. DF9 can be observed in the picture below:

Installation of the Module into the Rack R700-4
The SW-700 module can be installed in the rack, powered by the bus rack. The Rack R700-4 is
ready for mounting in DIN rail. The steps for the module installation are showed below:
Rack - R700-4
Attach the top of the module (with a 45oinclination) to the
module support located on the upper part of the rack.
Mounting detail.
Push the module fixing it to the module connector.
Next, fix the module to the rack using a screwdriver, and
fasten the fixation screw at the bottom of the module.

Redundant Power Supply Operation
The SW-700 may be powered externally or through the IMB. So, it supports power supply
redundancy. The user must set jumpers in order to configure the main power.
Find the jumper at the bottom of the module box. With the aid of a plier set the position of the
jumpers according to the operation mode.
