Description

Field

Indicates the following:

•

For EX3200 switches; and for EX2200, EX2200-C, EX2300,
EX2300-C, EX3300, EX3400, EX4200, EX4300, EX4500,
and EX4550 switches that are not configured as Virtual
Chassis, the value displayed in the Inventory details field is
always 1 FPC. FPC is a legacy term for a slot in a large Juniper
Networks chassis, which simply refers to the standalone
switch.

•

For EX2200, EX2200-C, EX2300, and EX2300-C switches
configured as a Virtual Chassis, the value displayed in the
Inventory details field is 1–4 FPC, with the number
corresponding to the number of member switches.

•

For EX3300 switches configured as a Virtual Chassis, the
value displayed in the Inventory details field is 1–6 FPC, with
the number corresponding to the number of member
switches.

NOTE:

For Junos OS Release 14.1X53-D10 and later, EX3300

switches configured as a Virtual Chassis display the value
1–10 FPC in the Inventory details field.

•

For EX3400 switches configured as a Virtual Chassis, the
value displayed in the Inventory details field is 1–10 FPC,
with the number corresponding to the number of member
switches.

•

For EX4200, EX4500, and EX4550 switches configured as
a Virtual Chassis, the value displayed in the Inventory details
field is 1–10 FPC, with the number corresponding to the
number of member switches.

•

For EX6210 switches, the values displayed in the Inventory
details field are 1–2 CB and 1–9 FPC. CB, or Control Board,
refers to the SRE module. FPC refers to line cards and the
FPC within the CB.

•

For EX8208 switches, the values displayed in the Inventory
details field are 1–3 CB and 0–8 FPC. CB, or Control Board,
refers to SRE and SF modules. FPC refers to line cards.

•

For EX8216 switches, the values displayed in the Inventory
details field are 1–2 CB and 0–16 FPC. CB, or Control Board,
refers to RE modules and FPC refers to line cards.

•

For an XRE200 External Routing Engine in an EX8200 Virtual
Chassis, the value displayed in the Inventory details field is
1 XRE. XRE refers to RE modules. For XRE200 External
Routing Engines configured as a Virtual Chassis, the values
displayed in the Inventory details are 1–2 XRE and 0–4 LCC,
where LCC refers to the EX8200 line card chassis.

Inventory details

Indicates the version of the Junos OS image. In a Virtual Chassis
configuration, the Junos OS image of the master switch is
displayed by default. To display the Junos OS image of a
specific switch, click the image of that switch.
