General system information
The General page displays the following general system information about the Digi
device, which can be useful in device monitoring and troubleshooting.
Information on the General System Information page includes:
Model
The model of the Digi device.
MAC Address
A unique network identifier. All network devices are required to have their own unique
MAC address. The MAC address is on a sticker on the Digi device. The number is
displayed as 12 hexadecimal digits, usually starting with 00:40:9D.
Firmware Version
The current firmware version running in the Digi device. This information may be used
to help locate and download new firmware. Firmware updates can be downloaded from
http://support.digi.com/support/firmware.
Boot Version
The current boot code version running in the Digi device.
POST Version
The current Power-On Self Test (POST) code version running in the Digi device.
CPU Utilization
The amount of CPU resources being used by the Digi device.
Important: 100% CPU Utilization may indicate encryption key generation is in-
progress. A CPU usage this high may indicate that encryption key generation is in-
progress. On initial boot, the Digi device generates some encryption key material: an
RSA key for SSL/TLS operations, and a DSA key for SSH operations. This key-
generation process can take as long as 40 minutes to complete. Until the corresponding
key is generated, the Digi device will be unable to initiate or accept that type of
encrypted connection. It will also report itself as 100% busy but, since key generation
takes place at a low priority, the device will still function normally. On subsequent
reboots, the Digi device will use its existing keys and will not need to generate another
unless a reset to factory defaults is done, which will cause a new key to be generated on
the next reboot.
