EX4100-F Chassis

The EX4100-F switch chassis is a rigid sheet-metal structure that houses all components of the switch.

• For the cooling system to function properly, the airflow around the chassis must be unrestricted.

• If you are mounting the switch in a rack or cabinet with other equipment, or if you are placing it on the desktop or floor near other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.

• Leave at least 24 in. (61 cm) in front of the switch and behind the switch. For service personnel to remove and install hardware components, you must leave adequate space at the front and back of the switch. It is recommended that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack or cabinet.

EX4100-F switches have four chassis status LEDs (labeled SYS, ALM, MST, and CLD) on the rightside of the front panel .

Table 5 describes the chassis status LEDs labeled SYS, ALM, and MST on an EX4100-F switch. The table also describes their colors and states and the status each LED indicates. You can view the colors of the LEDs remotely through the CLI by issuing the show chassis led operational mode command. All LEDs can be lit simultaneously.

For information on the blink patterns of the CLD LED, which provide the cloud connection status of the switch, see Cloud Ready LED Blink Patterns or see Cloud Connection Process to understand how the cloud connection works.

The management port, labeled MGMT, on the rear panel of EX4100-F switches has two LEDs that indicate link activity and port status.

The following table describes the LEDs.

The RJ-45 network ports, SFP+ uplink ports, and SFP+/SFP28 Virtual Chassis Ports on EX4100-F switches have LEDs that show the link activity and port status.

LEDs on the Network Ports

The figures in this section show and describe the LEDs on the following ports:

• Figure 8 shows the LEDs on the RJ-45 network ports on EX4100-F switches.

• Figure 9 shows the LEDs on the SFP+ uplink ports.

• Figure 10 shows the LEDs on the SFP+/SFP28 Virtual Chassis Ports.

• Table 7 describes the link activity LED state and description on the RJ-45 ports, SFP+ uplink ports, and SFP+/SFP28 Virtual Chassis Ports.

Note:

The status LEDs on the port number 24 - 47 will be updated with a delay which varies from 1 second to 9 seconds when a cable is plugged or unplugged.

Table 7: Link Activity LED on the Network Ports, Uplink Ports, and Virtual Chassis Ports

Link Activity LED Color	Link Status LED State and Description
Green	On steadily—The port and the link are active, but no link activity is occurring. Blinking—The port and the link are active, and link activity is occurring. Off—The port is not active.

EX4100-F switches have network port mode LEDs (labeled SPD, DX, EN, and POE) on the right side of the front panel (see Figure 11.) These LEDs indicate the status of the network ports. Use the mode button on the right side of the front panel to toggle the status LEDs. You toggle the status LEDs to show the different port parameters for the network ports. The LED that is lit indicates the port parameter. Table 8 describes the status LEDs.

Note:

The LED labeled PoE is not available on switch models with network ports that do not provide PoE.

Table 8: Port Status of Network Ports Based on States of Port Mode LEDs

LED	Color	State and Description
SPD	Green	Indicates the speed. The speed indicators are as follows: On steadily—1000 Mbps On steadily (for EX4100-F uplink and virtual chassis ports)—10 Gbps Blinking—100 Mbps Blinking; 1 blink per second (for EX4100-F uplink and virtual chassis ports)—1000 Mbps Blinking; 3 blinks per second (for EX4100-F uplink and virtual chassis ports)—25 Gbps Unlit—10 Mbps
DX	Green	Indicates the duplex mode. The status indicators are as follows: On steadily—The port is set to full-duplex mode. Unlit—The port is set to half-duplex mode.
EN	Green	Indicates the administrative status. The status indicators are as follows: On steadily—The port is administratively enabled. Unlit—The port is administratively disabled.
POE	Green	Indicates the PoE mode. The status indicators are as follows: On steadily—PoE is enabled on the port, and a device is drawing power. Blinking—PoE is enabled on the port, but nothing is drawing power from the port. Unlit—PoE is not enabled on the port.
