Page 2: Specifications
FEDERAL COMMUNICATIONS COMMISSION INDUSTRY CANADA RADIO FREQUENCY INTERFERENCE STATEMENTS This equipment generates, uses, and can radiate radio-frequency energy, and if not installed and used properly, that is, in strict accordance with the manufacturer’s instructions, may cause interference to radio communication. It has been tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial environment. - Page 3 2. Introduction The 2U Auto Bypass Switch is a multiple port A/B switch that is designed to automatically switch between a normal network path and a “bypass” or “failover” path for 10/100/1000/10G Ethernet network environments, or multimode fiber based Ethernet environments. It consists of a 2U high, 19 inch rackmount card cage, a power supply card plus external 100-240 VAC power supply module (with an option for a second external power supply module for redundant power), and from 1 to 5 groups of Auto Bypass Switch module cards.
- Page 4 3. Configuration 3.1 A/B Switch Card Configuration Figure 3.1.1 – Typical A/B Switch Card Front & Rear Panels Each A/B Switch Card has an 8-position DIP switch, used to set the card’s address. Switch position 1 is the least significant bit, and position 8 is the most significant bit. Set each switch position ON (as marked) for a '0', and OFF for a '1'.

- Page 7 • IP address and MAC address of the external Ethernet node that the 2U Auto Bypass Switch is to monitor in order to determine when to switch between the normal and the bypass paths. A value of 0.0.0.0 for the monitor IP address disables the auto bypass and auto recovery switching functions.

Page 8: Installation
4. Installation Find a location suitable for installing the 2U Auto Bypass Switch, with access to AC power outlets and the connections you intend to switch through the unit. If you intend to use serial control, connect to the RJ11 Gang In RS232 console port using the supplied DB9 to RJ11 adapter and RJ11 to RJ11 crossover cable. - Page 9 A typical failover application where a redundant or backup connection is required would have the host device connected to one of the “C” ports, with the normal network connection to the respective “B” port, and the failover network connection to the respective “A” port. The 2U Auto Bypass Switch provides two separate A/B switching elements, so two separate host devices can be connected to their own “normal”...
- Page 10 In a typical IPS environment, the NETWORK port on the 2U Auto Bypass Switch would be connected to an unused port on the edge router/switch mentioned in the example configuration in section 4.3 above. To provide auto bypass switching, the 2U Auto Bypass Switch should be configured to use the firewall’s IP and MAC addresses for the monitor IP address and monitor MAC address parameters.

Page 11: Operation
5. Operation Whenever the 2U Auto Bypass Switch is powered OFF, or if power fails, the non-latching relays in the 2U Auto Bypass Switch will be in the “A” position, connecting the devices/networks attached to the “A” ports to the “C” ports of both sets of A/B switching elements within the 2U Auto Bypass Switch. -

Page 13: Network Setup
6. Network Setup To perform the initial setup of the 2U Auto Bypass Switch you can use a serial terminal capable of 9600 baud, no parity, 8 data bits, and 1 stop bit. Connect this terminal to the RS232 console connector on the 2U Auto Bypass Switch using the supplied DB9 to RJ11 adapter and RJ11 to RJ11 crossover cable. -
Page 14: Console Commands
7. Console Commands The following commands are available from the console prompt of the unit. All commands are case insensitive, although several variable parameters are case sensitive (read/write community names and web password). Many of the command words such as GET, SET, SYSTEM, and PORT can all be abbreviated by the first letter of the command. - Page 15 GET RACK N This command is not supported in the 2U Auto Bypass Switch. If this command is issued to the 2U Auto Bypass Switch it will respond with the following: Rack Status: XXXXXXXXXXXXXXXX GET PORT N Displays the status of A/B switching element N (1-2). The response will be “A” or “B”. Port Status: B SET PORT N A[B] Sets the addressed A/B switching element N (1-2) to position A or B.
- Page 16 SET WEBPASSWORD string GET WEBPASSWORD Set or display the current web password. Note that this is a case sensitive field. Any change will not become permanent until a SAVE operation is performed. SET WEBTIMEOUT seconds GET WEBTIMEOUT Set or display the current web timeout in seconds. After a period of inactivity of this many seconds, the network module will request a login.
- Page 17 whether or not the normal and/or bypass path is operational. This value is entered as a series of six HEX characters with spaces between each HEX character. If monitoring connectivity to a device on the same subnet as the 2U Auto Bypass Switch’s internal Ethernet node, set the monitormac address parameters to the MAC address of the device being monitored.
- Page 18 GET MANAGER N Display SNMP manager N (1-16) IP address. GET MANAGER Display all SNMP manager IP addresses. SAVE Save settings for next startup. All settings are stored in non-volatile memory and restored upon power on. Changes to parameters will not become permanent unless a SAVE operation is performed. (Save followed by reset command) RESET Causes a network system reboot and reloads all parameters from stored settings.

8. Web Interface The network module provides access to console commands through a web browser interface. When enabled (see SET WEBENABLE command) accessing the default page on the modules IP address (index.html) will present the following page (or similar). Note: If using a pop up blocker on your web browser, be sure to allow pop ups from the IP address of the Auto Bypass Switch, otherwise you could experience trouble receiving a response through the interface. - Page 20 Web Interface Version 1.0 Copyright (c) 2007 All rights reserved.
