• EX4300-24T
• EX4300-24P
• EX4300-32F
• EX4300-48T
• EX4300-48P

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.

FPC (n)

Abbreviated name of the Flexible PIC Concentrator (FPC)

• EX4300-24T
• EX4300-24P
• EX4300-32F
• EX4300-48T
• EX4300-48P

n is a value in the range 0 through 9.

Understanding Interface Naming Conventions on EX Series Switches

On a standalone switch, the default value is 0.

In this case, FPC refers to the switch itself.

On 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.

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. In the CLI output, the network ports are numbered 0 through 31 and the SFP+ uplink ports are numbered 32 through 35.

Power supply (n)

One of the following:

• JPSU-350-
  AC-AFO-A
• JPSU-350-
  AC-AFI-A
• JPSU-550-

• JPSU-550-
  DC-AFI-A
• JPSU-715-
  AC-AFO-A
• JPSU-1100-
  AC-AFO-A

n has a value 0 or 1, corresponding to the power supply slot number.

AC power supply or DC power supply

• AC Power Supply in EX4300 Switches
• DC Power Supply in EX4300 Switches

Caution: Do not mix:

• AC and DC power supplies in the same chassis.
• Power supplies with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis.
• Fan modules with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis.
• Power supplies and fan modules with different airflow labels (AIR IN (AFI) and AIR OUT (AFO)) in the same chassis.

Note: The 32-port EX4300 switches support fan modules and power supplies with the AIR OUT (AFO) label only.

Fan tray

• Fan Module, Airflow In (AFI)
• Fan Module, Airflow Out (AFO)

n has a value 0 or 1, corresponding to the fan module slot number.
