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

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

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.

 

Understanding Interface Naming Conventions on EX Series Switches

One of the following:

  • 24x 10/100/1000
    BASE-T
  • 48x 10/100/1000
    BASE-T
  • 32x1G SFP

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.

EX4300 Switches Hardware Overview

  • For 24-port and 48-port switches: 4x40GE
  • For 32-port switches: 2x40GE

PIC 1

Built-in QSFP+ ports

EX4300 Switches Hardware Overview

  • For 24-port and 48-port switches:

    4x 1G/10G SFP/SFP+

  • For 32-port switches, one of the following:
    • 8x1G/10G SFP/SFP+
    • 2x40GE

PIC 2

Uplink module installed in the switch

Uplink Modules in EX4300 Switches

Xcvr (n)

Abbreviated name of the transceiver

n is a value equivalent to the number of the port in which the transceiver is installed.

Optical transceivers

Pluggable Transceivers Supported on EX4300 Switches

Power supply (n)

One of the following:

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

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

One of the following:

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

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