1024 alarm or status change events in chronological order, with the most recent events
at the top of the list. This can be very useful for diagnostics and testing, as it identifies
the source of each event in the Alarm column, the event type or status in the
Description column, and the queue status of each event in the Sent column.
Events which are listed as Annunciated in the Sent column have been successfully
transmitted to the SMS Collator if the system has one, or to the SMS itself if there is no
Collator operating.

2.4.8 System Status / Diagnostics
This section displays a list of the local Comander Rack's Fixed/Diagnostics circuits,
and their status. These are "virtual" circuits – they provide real-time diagnostic and
status information about various aspects of the Comander Rack's internal processes,
and annunciate this information to the SMS as alarm or tamper conditions on "Fixed
Circuits".
You can enable or disable the Fixed Circuits using a setting on the General Hardware
Settings page of the Configurator. If Fixed Circuits are enabled, they are appended to
the end of the physical circuits list annunciated to the SMS – see section 2.5.4.12.5.4.1
below for more information.
2.4.9 SSL Certificates
This section displays the current status of your Comander Rack's SSL certificate
configuration, and provides upload functions for installing new SSL certificate files.
2.4.9.1 What is an SSL Certificate?
In any network information system which uses the "HTTPS" protocol to secure
communications between a client (web browser) and a server (in this case the
Configurator), an SSL Certificate serves two purposes –
• to identify the server by referring the certificate to a recognised Certificate
Authority;
• to encrypt the request and response information which is sent over the network
during each HTTPS request/response transaction.
Comander systems require encryption for Configurator operations, so all Comander
units have factory-installed SSL certificates to make this possible. But in terms of
server identification and certificate authority, there are two ways in which the system
can be specified:
• using generic SSL certificates issued by Geoquip;
• using custom or commercial SSL certificates.
2.4.9.2 Using Generic Certificates
If your Comanders use generic SSL certificates issued by Geoquip, your browser will
display some kind of security alert when you first access each Rack's Configurator
login page. The wording of this alert depends on the browser you are using, but you
need to choose the browser option to trust the certificate permanently, so that future
logins to that Rack's Configurator will not generate security alerts.
2.4.9.3 Using Custom Certificates
If you also want to use SSL certificates to verify the identity of each Comander Rack
unit via a Certificate Authority whenever anyone accesses its Configurator, you will
need to provide certificate files using the X509 standard, and upload the files to your
