Chapter 3: Configuration
3. Configuration
The rack address is the only user-configurable setting that typically needs to be set on the Pro Switching System 4 Network Backup Switch prior to initial installation. Switch SW2 on the unit is used to set the rack’s address. The rack address identifies the rack number when remotely accessing the switch through the serial port or Ethernet port. The rack address can be set from 0x01 to 0xFF hex, with position 1 as the least significant bit and position 8 as the most significant bit. A switch in the ON position is a low or 0 bit, while a switch in the OFF position is a high or 1 bit. Address 0x00 is invalid and must not be used (it is used for factory test only). Each Pro Switching System 4 rack within a multi-rack daisychained system of racks must have a unique address. The first rack in the system should be assigned address 0x01, the next rack address 0x02, and so on through 0xFF. If a(n) (Ethernet) network manageable switch is used in a multi-rack system, it must be the first rack in the daisychained system of racks, and its address must be set to address 0x01. Only one (Ethernet) network manageable switch is permitted per multi-rack system.
NOTE: SW2 is located nearest the DB9 connector, with position 1, the least significant bit, located closest to the DB9 connector.
Network manageable models of the switches (models that include a remote Ethernet management interface) also require several parameters related to TCP/IP operation to be configured via the serial RS-232 port on the switch before the Ethernet remote interface can be used. These settings are described in Section 5.4 and Chapter 6 later in this manual.
All other jumpers and DIP switch settings inside the switch have been pre-configured at the factory and should not be changed from their default settings. They are shown here for reference only.
Jumpers W4 & W5 should be set as follows:
•Both to position 1-2 if there is no Ethernet Module installed.
•Both to position 2-3 if there is an Ethernet Module installed (Network Manageable Models).
WARNING: Damage may occur to the Ethernet Module and/or microcontroller if these jumpers are set to Position 1–2 with an Ethernet Module installed.
NOTE: DIP switch SW1 sets the number of physical ports available for use. They are set at the factory and should not be changed. DIP switch SW2 sets the unit’s rack address.
NOTE: SW1 is located next to SW2, further from the DB9 connector, with position 1, the least significant bit, located closest to the DB9 connector. SW1 settings are shown for reference—they are set at the factory and should not be changed.
