Additional Information

Chassis

One of the following:

  • EX4300-24T

  • EX4300-24P

  • EX4300-32F

  • EX4300-48T

  • EX4300-48P

Switch chassis

Identifying EX4300 Switch Models

Routing Engine (n)

One of the following:

  • EX4300-24T

  • EX4300-24P

  • EX4300-32F

  • EX4300-48T

  • EX4300-48P

  • EX4300-48MP

n is a value in the range 0 through 9.

  • On a standalone switch, the default value is 0.

  • On a Virtual Chassis configuration, the values correspond to the member IDs of switches configured in the master role and the backup role in the Virtual Chassis.

Routing Engine

FPC (n)

Abbreviated name of the Flexible PIC Concentrator (FPC)

One of the following:

  • EX4300-24T

  • EX4300-24P

  • EX4300-32F

  • EX4300-48T

  • EX4300-48P

  • EX4300-48MP

n is a value in the range 0 through 9.

 

Understanding Interface Naming Conventions

On a standalone switch, the default value is 0.

In this case, FPC refers to the switch itself.

In a Virtual Chassis configuration, the values correspond to the assigned member IDs of switches in the Virtual Chassis.

In this case, the FPC number refers to the member ID assigned to the switch.

PIC (n)

Abbreviated name of the Physical Interface Card (PIC)

n is a value in the range 0 through 2.

 

Understanding Interface Naming Conventions

One of the following:

  • 24x 10/100/1000BASE-T

  • 32x1G SFP

  • 48x 10/100/1000BASE-T

  • 24x10M/100M/1G Base-T & 24x 100M/1G/2.5G/5G/10G Base-T

PIC 0

  • In 24-port and 48-port switches—PIC 0 stands for built-in network ports numbered 0 through 23 or 0 or through 47.

  • In 32-port switches—PIC 0 stands for built-in network ports followed by SFP+ uplink ports. The network ports are labeled 0 through 31 and the SFP+ uplink ports are labeled 0 through 3. In the CLI output, the network ports are numbered 0 through 31 and the SFP+ uplink ports are numbered 32 through 35.
