Protection Mode
Protection mode is a state where the device is operational but has
implemented defenses against disruptive changes that could take the product out of service.
Implicit Protection Mode
Implicit protection mode helps prevent configuration changes that can affect system
behavior and cause unintended and unforeseen changes. This security enhancement is
automatically triggered as soon as one of the following occurs:
- When the adapter has an open Status connection
- When an I/O module in the chassis has an open I/O connection
In protection mode, the device deactivates services that could disrupt the operation of the
device. For example, some configuration operations or firmware updates are disabled to not
impact the operation of the device.
When the device is in protection mode, the mode prevents the following actions:
- Change Ethernet port configuration settings
- Change of NFC mode
- Change network address IP settings
- Disable or re-enable Ethernet ports
- Update the adapter firmware
- Perform any adapter resets
- Change configuration
- Disable or enable the web server
- Disable or enable the SNMP server
- Update the web server configuration pages
Explicit Protection Mode
Explicit protection mode is an additional security enhancement which is triggered when
explicitly enabled. This security enhancement occurs at the module level and helps prevent
unauthorized configuration changes that can affect system behavior and cause unintended and
unforeseen changes.
When the device is in explicit protection mode, only certain requests and configuration
changes are accepted until explicit protection mode is explicitly disabled.
The device enters explicit protection mode when rotary switches are set to value 900 during
powerup. To enable explicit protection mode, do the following:
- Note the current position of the rotary switches.
- Power down the device.
- Set the rotary switches to 900, then power up the device.The device confirms explicit protection mode with the following status indicator flashing sequence:
- Module status indicator = Flashing red
- All other status indicators = Off
- Power down the device and restore previous values to the rotary switches.
- Power up the device to normal operation with Explicit Protection Mode enabled.
To disable explicit protection mode, do the following:
- Note the current position of the rotary switches.
- Power down the device.
- Set the rotary switches to 000, then power up the device.The device confirms exiting explicit protection mode with the following status indicator flashing sequence:
- Module status indicator = Flashing red
- All other status indicators = Off
- Power down the device and restore previous values to the rotary switches.
- Power up the device to normal operation with Explicit Protection Mode disabled.
