Chassis Physical Specifications for EX4100-H Switches
The EX4100-H switch chassis is a rigid sheet-metal structure that houses all components of the switch Table 1 summarizes the physical specifications of the EX4100-H switch chassis.
Figure 1: Clearance Requirements for Thermal Performance (Airflow) and Hardware Maintenance for EX4100-H-12MP Switches
The following are some points to note when installing the switches:
-
For the cooling system to function properly, the airflow around the chassis must be unrestricted.
-
If you are mounting the switch in a cabinet with other equipment ensure that the exhaust from other equipment does not blow into the intake vents of the chassis. The temperature within the cabinet is greater than room temperature outside the cabinet. Ensure temperature inside the enclosure conforms to environmental specification. See Table 2.
-
Clearance requirements for thermal performance
-
Leave at least 2 in around the device except mounting side for proper airflow around the units and the fin surface.
-
-
Clearance requirements for hardware maintenance
-
Leave at least 24 in around the device except mounting side for proper airflow around the units and the fin surface.

Chassis Status LEDs on EX4100-H Switches
EX4100-H switches have four chassis status LEDs (labeled SYS, ALM, MST, and CLD) on the rightside of the front panel .
Figure 3: Chassis Status LEDs in EX4100-H-12MP Switches
1 — Chassis status LEDs |
Table 3 describes the chassis status LEDs labeled SYS, ALM, and MST on an EX4100-H switch. The table also describes the LED color patterns and their status descriptions. You can view the colors of the LEDs remotely through the CLI by issuing the show chassis led
operational mode command. Note that 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.
LED Label | Color | State and Description |
---|---|---|
SYS | Green |
|
Unlit | The switch is powered off or is halted. | |
ALM | Red | A major hardware fault—such as a temperature alarm or a power failure alarm—occurred, and the switch is halted. A major alarm indicates a critical error condition that requires immediate attention (see Chassis Component Alarm Conditions on EX4100-H Switches). |
Amber | A minor alarm—such as a software or a hardware error—occurred. Power off the switch and then power it back on. Monitor the switch to see whether it is working properly. A minor alarm indicates a non-critical condition that requires monitoring or maintenance. A minor alarm that is left unchecked might cause interruption in service or performance degradation. | |
Unlit | No alarm is in effect, or the switch is halted. | |
MST | Green | In a standalone switch:
|
In a Virtual Chassis configuration:
|
Note:
When issuing show system alarms
, only the ALM LED of the master switch in a virtual chassis system glows to display the alarm state. Backup switch and linecard ALM LEDs will be unlit. However, when issuing show chassis alarms
, ALM LED glows on all of the individual member switches, displaying their individual alarm states.
Note:
For Virtual Chassis deployments managed from the cloud, the CLD LED on individual Virtual Chassis members will reflect the state of the Master, except when a software download is in progress. When a software download is in progress, the CLD LED on a Virtual Chassis member will display the Junos OS upgrading LED pattern and color.
LEDs on the Management Port on EX4100-H Switches
The management port, labeled MGMT, on the front panel of EX4100-H switches has two LEDs that indicate link activity and port status (see Figure 4 ).

PSU Status LEDs on the EX4100-H-12MP Switch Chassis
The PSU 0 and PSU 1 LEDs on the chassis display status of the external PSUs connected to the switch. See Figure 5.
Figure 5: LEDs on the Chassis to Indicate PSU Connection Status
Table 5 describes the colors and statuses of the LEDs.
PSU LED Label | Color | State and Description |
---|---|---|
PSU 0 PSU 1 | Green | 54V output OK or 12V output OK The external PSU is connected to the PSU connector (PSU 0 and/or PSU 1) on the switch. |
Off | Status can be one of the following

LEDs on the RJ-45 Network Ports, Virtual Chassis Ports, and Uplink Ports on EX4100-H Switches
The RJ-45 network ports, SFP+ uplink ports, and SFP+ Virtual Chassis Ports on EX4100-H 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 6 shows the LEDs on the RJ-45 network ports on EX4100-H switches.
-
Figure 7 shows the LEDs on the SFP+ uplink ports.

EX4100-H switches have network port mode LEDs (labeled SPD, DX, EN, and POE) on the right side of the front panel (see Figure 9). 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 7 describes the status LEDs.
Note:
The LED labeled PoE is not available on switch models with network ports that do not provide PoE.
