Dashboard for EX Series Switches

When you log in to the J-Web user interface, the dashboard for the EX Series switch appears. Use the dashboard to view system information.

The dashboard comprises four panels and a graphical chassis viewer. You can click Preferences to choose which panels are to be displayed and set the refresh interval for chassis viewer information. Click OK to save your preference changes and return to the dashboard or click Cancel to return to the dashboard without saving changes.

Note: You can drag and drop the various panels to different locations in the J-Web window.

System Information Panel

Table 1: System Information

Field	Description
System name	Indicates the local name of the EX Series switch.
Device model	Indicates the model of the EX Series switch. Note: For an EX8208 switch or an EX8216 switch, the Device model information changes with respect to the selected line card, the Switch Fabric and Routing Engine (SRE) module in an EX8208 switch, or the Routing Engine (RE) module in an EX8216 switch.
Inventory details	Indicates the following: For EX2200 switches, for EX3200 switches, for EX4200 switches not configured as Virtual Chassis, and for EX4500 switches, the value in Inventory is always 1 FPC. FPC is a legacy term for a slot in a large Juniper Networks chassis; here, it simply refers to the single switch. For an EX4200 switch configured as a Virtual Chassis, the value in Inventory is displayed as 1–10 FPC, with the number corresponding to the number of member switches. For an EX8208 switch, the values in Inventory are displayed as 1–3 CB and 0–8 FPC. Control board (CB) refers to SRE and SF modules. FPC refers to line cards. For an EX8216 switch, the values in Inventory are displayed as 1-2 CB and 0-16 FPC. Control board (CB) refers to RE modules. FPC refers to line cards.
Junos image	Indicates the version of the Junos OS image.
