Chapter 3: Multiple Users Accessing a Chassis
How Does the Multi-User Feature Work?
SmartBits System Reference 37
Changing Multi-user Status
You must give ports a "Released" group (green status light) assignment in the Group
column to make those ports available to other users. The second user automaticallly
accesses and reserves all port numbers (now blue status for the second user) that have been
released by the first user. Therefore, the second user must give ports a "Released" group
(green status light) assignment in the Group column to make those ports available to the
third user.
If any user fails to give the Released group assignment to ports presented to him, all
subsequent users will access the SmartBits chassis and see no ports as available.
Cards reserved by you are released:
• when you disconnect from the chassis with the Actions > Disconnect command
or
• when you assign the Group column Released parameter to a port.
In SmartxDSL
When you connect to a SmartBits chassis, all ports are automatically reserved for your use
unless otherwise specified in the Setup menu Preferences window or already reserved by
another user. While the chassis is reserved, it is not available to another user or to any
other Spirent Communications application.
When you connect to a multi-user chassis, only cards available (not in use by another user)
AND appropriate to the specific set of tests, will be displayed in Available Trunk and
Access ports columns.
By default, the program reserves all cards and releases cards not selected after 10 minutes.
However, if a test is begun during the 10-minute reserved time, the cards not selected will
not be released until the test finishes and a new 10-minute reserved time period expires.
In the Setup > Preferences window, you can specify that the program automatically
reserves all cards upon connection and does not release them after a time period.
To see all ports available in each chassis, select Setup > SmartBits Reservations.Upto8
chassis controllers may be accessed at one time; each chassis controller may control up to
4 chassis or 80 ports.
The ownership status light (left-hand LED) indicates the multi-user status of each port:
• Blue – the port is reserved to you.
• Green – the port is available to other users (has not been reserved by you).
• Red – the port is reserved by another user.
The ownership status light only reflects the status of the SmartCards since the initial
connection to SmartBits or since the last Refresh. It is possible for a port to be reserved by
another user in the time between the last refresh and your attempt to configure or use the
port.
