EX4100-F System Overview

EX4100-F Switches Hardware Overview

The EX4100-F are suitable for small, medium, and large campus and branch enterprise deployments. You can use the switch models in high, medium, or low-density environments, because these models offer flexibility in terms of architecture and capabilities.

EX4100-F (fixed-form) switch models are:

Fanless models using external power supply adaptors

  • EX4100-F-12T and EX4100-F-12P

Models with built-in fans and power supplies

  • EX4100-F-24T, EX4100-F-24P, EX4100-F-48P, and EX4100-F-48T

You can manage EX4100-F switches from the cloud and on premise. The switches allow for simple, efficient, and scalable network management using cloud-based hosted management applications, on-premise management tools, and APIs.

Because EX4100-F switch models support Layer 2 (L2) and Layer 3 (L3) technologies, you can deploy them anywhere: core, distribution, or access layer. This aspect of the switch models also allows for a network overlay that provides uniform multisite connectivity.

You can manage EX4100-F switches from the CLI.

Compact solution—The EX4100-F family of switches are single-rack unit devices. They are ideal solutions for crowded wiring closets and access switch locations such as data centers, campuses, and branch offices. They provide carrier-class reliability of modular systems with the economics and flexibility of stackable platforms.

Virtual Chassis—EX4100-F switches support Virtual Chassis technology. You can interconnect up to 10 EX4100 and/or EX4100-F switches to form a Virtual Chassis.

High availability—EX4100-F switches provide high availability through redundant power supplies and fans, graceful Routing Engine switchover (GRES), and nonstop bridging and routing when deployed in a Virtual Chassis configuration.

Mist Cloud managed—EX4100-F switches are built to be cloud native. You can manage activities and features such as onboarding, fast bootup, streaming telemetry, and fast changes (JET) from the Mist cloud. Even though the EX4100-F switches are built specifically for management in the Mist cloud, you can manage them on premise if you prefer.

EVPN VXLAN —EX4100-F switch models can act as L2 and L3 VXLAN gateways to support a mix of legacy endpoints and newer devices. In combination with VXLAN, EVPN provides the capability to connect a multi-site enterprise customer network in an open and standards-based manner.

Multigigabit—Newer wave 2 and 802.11ax access points can use higher interface speeds on network switches to support higher scale and bandwidth for users and applications.

Virtual Chassis

EX4100-F switches have dedicated Virtual Chassis ports (VCPs) that you can use to interconnect member switches of a Virtual Chassis. Only homogenous virtual chassis is supported; that is, you can connect any EX4100-F switch, including EX4100 gigabit and EX4100-F multigigabit switches, in a virtual chassis. You can interconnect a maximum of 10 switches to form a Virtual Chassis. You can operate these interconnected switches as a single, logical device with a single IP address. If you operate the interconnected switches as a single device, you must use all the Virtual Chassis ports as Virtual Chassis ports or use all of them as network ports. You cannot mix multiple types of ports within a single, logical device.

For more information about Virtual Chassis, see Understanding EX Series Virtual Chassis.

Power over Ethernet Ports

EX4100-F switches are available with or without Power over Ethernet (PoE) or Power over Ethernet Plus (PoE+/PoE++) capability. Models that support PoE, PoE+, or PoE++ provide that support on all of their RJ-45 downlink ports. The switch models provide perpetual and fast PoE functionality. PoE, PoE+, and PoE++ ports provide electrical current to devices—such as IP phones, wireless access points, and security cameras—through network cables. Because the network cables provide electrical current, you do not need separate power cords for those devices.

  1. The EX4100-F-24P and EX4100-F-48P switch models support PoE+ (30 W) by default.

  2. The EX4100-F-12P switch model supports PoE+ (30 W) by default.

For more information about PoE support on EX series switches, see Understanding PoE on EX Series Switches.

Note:

IEEE 802.3at class 4 powered devices require category 5 or higher Ethernet cables.

Powered Device

The powered device (PD) feature of EX4100-F-12P allows the switch to be powered by another PoE switch which supports 802.3bt (ex: EX4400 PoE switches or EX4100-24MP/48MP). It is done by connecting one or two of the two 1/2.5/5/10 Gbps Base-T uplink ports on the rear panel of a EX4100-F-12P switch to the downlink ports on the front panel of the power-providing switch. The EX4100-F-12P switch can also use AC power source whilst being powered by another switch.

Figure 1: EX4100-F-12P switch connected as a powered device EX4100-F-12P switch connected as a powered device

In addition to being able to draw power to power itself, the EX4100-F-12P switch can also power other devices because it has PoE+ enabled ports. The amount of power available to the switch to be able to power other devices is dependent on some factors. Because the switch only consumes 60W, any additional power supplied to it is available to the switch to power other devices. In Table 2, the PoE budget details of the switch are described. The PoE budget of EX4100-F-12P varies depending on whether it is connected to:

  • Only the AC power source via the 280w power supply adaptor

  • AC power source and a PoE++ PSE (power supply equipment) as a powered device via any one of the two 1/2.5/5/10G base T uplink ports on the rear panel

  • AC power source and a PoE++ PSE as a powered device via both the 1/2.5/5/10G base T uplink ports on the rear panel

EX4100-F Cooling System

EX4100-F-24P, EX4100-F-24T, EX4100-F-48P, and EX4100-F-48T switch models have built-in fans. EX4100-F-12P and EX4100-F-12T are fanless switch models that have natural convection cooling. The airflow direction depends on the fan modules and power supplies installed in the switch. You can order an EX4100-F switch that supports front-to-back airflow or back-to-front airflow, as follows:

  • Front-to-back airflow: Air enters through the front of the switch.

  • Back-to-front airflow: Air enters through the back of the switch.

The fan modules are hot-removable and hot-insertable field-replaceable units (FRUs) installed in the rear panel of the switch. You can remove and replace the FRUs without powering off the switch or disrupting switch functions.

EX4100-F Power System

The following list presents the EX4100-F switch models with their compatible power systems:

  • EX4100-F-12P doesn't have PSU FRUs or built-in power supplies. It uses an external 280W power adapter.

  • EX4100-F-12T doesn't have PSU FRUs or built-in power supplies. It uses an external 75W power adapter.

  • EX4100-F-24P uses the built-in 450W AC power supply.

  • EX4100-F-24T uses the built-in 65W AC power.

  • EX4100-F-48P uses the built-in 850W AC power supply.

  • EX4100-F-48T uses the built-in 90W AC power supply.

CAUTION:

Avoid mixing:

  • AC and DC power supplies in the same chassis.

  • Power supplies with different airflow directions in the same chassis.

  • Fan modules with different airflow directions in the same chassis.

  • Power supplies and fan modules with different airflow directions in the same chassis.

If you install power supplies or fan modules with different airflow directions, Junos OS raises an alarm.

Uplink Ports

EX4100-F switches have autosensing uplink ports that you can use to connect an access switch to a distribution switch. The uplink ports on the front panel (rear panel on EX4100-F-12P and EX4100-F-12T switches) are configured as network ports by default. You cannot use the uplink ports as Virtual Chassis ports. The uplink ports on the front panel support 1-gigabit SFP transceivers and/or 10-gigabit SFP+ transceivers. You can use a combination of SFP and SFP+ transceivers. Uplink ports for EX4100-F-12P and EX4100-F-12T switches are located on the rear panel - these are 1/2.5/5/10 GE BASE-T RJ-45 uplink ports. On the EX4100-F-12P, these uplink ports can be used to power the device - see Powered Device.

For a list of supported transceivers, see Pluggable Transceivers and Cables Supported on EX4100-F Switches.
