3 - 6 ONline 10BASE-T Security Module Installation and Operation Guide
Network selection switches 1 and 2 enable you to select a channel for the
module. Switches 1 and 2 are factory set to On. Therefore, the Security
Module is initially configured to network 1. To reconfigure the module to a
different network, refer to the information in .
Switch 3 (Security) allows you to enable or disable Security mode and
enable or disable port mode for all 12 ports on the Security Module. Switch
3 is configured to affect both Security mode and the port mode setting in
order to protect your ports in the event the management module fails.
When the Security switch is set to enabled, port mode is set to disabled.
Conversely, when the Security switch is set to disabled, port mode is set to
enabled.
This dual purpose setting provides maximum security for all ports on the
Security Module and also provides you with the flexibility of using the ports
as non-secure ports in the event the management module fails. Without
management, you may elect to have traffic continue to pass through the
non-secure ports. However, your environment may require secure ports at
all times. In this situation, you would choose to disable the ports rather
than keep them enabled in a non-secure environment.
