The Update Available window appears if there is a latest update of the J-Web Application package available
on the Juniper Networks server. This window is enabled by the auto update feature of J-Web.
NOTE:
•
The Update Available window will not appear when you log in, if you have not selected the
Check for updates automatically on every login in the Update Preference section in the Maintain
> Update J-Web side pane. By default, the Check for update automatically on every login is
selected.
•
If you choose Update Later, you can update to the latest J-Web Application package by clicking
the orange icon next to Update Available on the top pane of the J-Web interface or through
Maintain > Update J-Web.
The dashboard comprises a graphical chassis viewer and four panels.
Graphical Chassis Viewer
The Dashboard panel displays a graphical view of the chassis of a switch. In a Virtual Chassis, it displays
a graphical view of each member switch.
In a Virtual Chassis, the default values are shown on the Dashboard panel when no chassis image is clicked.
The panel displays the value for a switch if you click its image.
NOTE:
•
If the member switch is not present, inactive, or not provisioned, you cannot expand the
member switch image.
In J-Web Application package Release 14.1X53-A2, you can form a Virtual Chassis using
EX4600 and EX4300 switches. When in a mixed Virtual Chassis consisting of EX4600 switches
and EX4300 switches, the EX4600 switches can be the primary, backup, or in the linecard role,
while the EX4300 switches must be in the linecard role.
•
Starting in J-Web Application Package Release 19.2A1, J-Web supports EX4650 switches.
NOTE: For EX4650 switches, chassis viewer supports only the standalone view and
does not support the Virtual Chassis configuration.
Table 103 on page 539 lists the details that are displayed on each member switch.
