Dell PowerConnect J-Series Ethernet Switch Complete Software Guide for Junos OS All J-EX4200 switches have dedicated 64-Gbps Virtual Chassis ports that allow you to connect the switches to each other. You can also use optional uplink module ports to connect members of a Virtual Chassis across multiple wiring closets. To provide carrier-class reliability, J-EX4200 switches include: • Dual redundant power supplies that are field-replaceable and hot-swappable. An optional additional connection to an external power source is also available. • A field-replaceable fan tray with three fans. The switch remains operational if a single fan fails. • Redundant Routing Engines in a Virtual Chassis configuration. This redundancy enables GRES (graceful Routing Engine switchover) and nonstop active routing. • Junos OS with its modular design that enables failed system processes to gracefully restart. Uplink Modules Optional uplink modules are available for all J-EX4200 switches. Uplink modules provide four 1-gigabit small form-factor pluggable (SFP) transceivers or two 10-gigabit small form-factor pluggable (SFP+) transceivers. You can use SFP or SFP+ ports to connect an access switch to a distribution switch or to interconnect member switches of a Virtual Chassis across multiple wiring closets. Power over Ethernet (PoE) Ports PoE ports provide electrical current to devices through the network cables so that separate power cords for devices such as IP phones, wireless access points, and security cameras are unnecessary. J-EX4200 switches have partial (8-port) PoE capability. Related • J-EX4200 Switch Models on page 26 Documentation • Field-Replaceable Units in J-EX4200 Switches • Site Preparation Checklist for J-EX4200 Switches J-EX4200 Switch Models The J-EX4200 switch is available with 24 or 48 ports and with partial Power over Ethernet (PoE) capability. Table 21 on page 26 lists the J-EX4200 switch models.

All J-EX4200 switches have dedicated 64-Gbps Virtual Chassis ports that allow you to

connect the switches to each other. You can also use optional uplink module ports to

connect members of a Virtual Chassis across multiple wiring closets.

To provide carrier-class reliability, J-EX4200 switches include:

•

Dual redundant power supplies that are field-replaceable and hot-swappable. An

optional additional connection to an external power source is also available.

•

A field-replaceable fan tray with three fans. The switch remains operational if a single

fan fails.

•

Redundant Routing Engines in a Virtual Chassis configuration. This redundancy enables

GRES (graceful Routing Engine switchover) and nonstop active routing.

•

Junos OS with its modular design that enables failed system processes to gracefully

restart.

Uplink Modules

Optional uplink modules are available for all J-EX4200 switches. Uplink modules provide

four 1-gigabit small form-factor pluggable (SFP) transceivers or two 10-gigabit small

form-factor pluggable (SFP+) transceivers. You can use SFP or SFP+ ports to connect

an access switch to a distribution switch or to interconnect member switches of a Virtual

Chassis across multiple wiring closets.

Power over Ethernet (PoE) Ports

PoE ports provide electrical current to devices through the network cables so that separate

power cords for devices such as IP phones, wireless access points, and security cameras

are unnecessary. J-EX4200 switches have partial (8-port) PoE capability.
