(SFP+) transceivers Cooling System The cooling system in an EX9208 switch is a field-replaceable unit (FRU). It consists of a hot-removable and hot-insertable fan tray. The fan tray contains six fans. The fan tray installs vertically on the right back of the chassis and provides side-to-side chassis cooling.
A base-configuration EX9208 switch ships with three low-line (100–120 VAC) or two high-line (200–240 VAC) AC power supplies. An AC-powered, redundant-configuration EX9208 switch ships with four low-line (100–120 VAC) or four high-line (200–240 VAC) AC power supplies. See “AC Power Supply in an EX9208 Switch” on page A DC-powered, redundant-configuration EX9208 switch ships with four DC power supplies.

Understanding EX9208 Switch Component and Functionality Redundancy The Juniper Networks EX9208 Ethernet Switches are available as fully redundant system. A redundant EX9208 switch configuration is designed so that no single point of failure can cause the entire switch to fail. See “EX9208 Switch Configurations”...
“DC Power Supply in an EX9208 Switch” on page Cooling system—The cooling system in EX9208 switches consists of fan tray and air filter. The fan tray contains six fans. Under normal operating conditions, the fans in the fan tray run at less than full speed. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the switch indefinitely.
You can install a line card or an SF module in the multifunctional slot labeled in EX9204 switches. The corresponding LED displays information depending on the hardware installed in that slot. Figure 8: Craft Interface in an EX9208 Switch 1— Host subsystem LEDs 6—...

Routing Engine modules (RE modules) are installed directly into Switch Fabric modules (SF modules). Each RE module houses one Routing Engine. An EX9204 or EX9208 switch can have either one or two Routing Engines. An EX9214 switch can have either two or three Routing Engines.
Engine is hot-pluggable. If only one RE module is installed, you must disable the switch before removing the RE module. A base configuration EX9204 and EX9208 switch has only one RE module. See EX9204 Switch Configurations and “EX9208 Switch Configurations” on page 7.
Switch Fabric modules (SF modules) are installed horizontally on the front panel of the switch chassis. You can install either one or two SF modules in an EX9204 or EX9208 switch and either two or three SF modules in an EX9214 switch. A base configuration EX9204 or EX9208 switch has only one SF module, and a base configuration EX9214 switch has two SF modules.
EX9208 Switch Hardware Guide In EX9204 and EX9208 switches, you can add a second SF module to the configuration for host subsystem redundancy. In EX9214 switches, you can add a third SF module to the configuration for host subsystem redundancy. If two SF modules are installed, one SF module functions as the master and the other functions as the backup.
You can install either one or two host subsystems in the front panel of an EX9204 or an EX9208 switch. A base configuration EX9204 and EX9208 switch has one host subsystem. A redundant configuration EX9204 and EX9208 switch has a second host subsystem.
Chapter 2: Chassis Components and Descriptions NOTE: In EX9204 and EX9208 switches, we recommend that you install two host subsystems for redundant protection. If you install only one host subsystem, we recommend that you install it in slot . In EX9214 switches, we recommend that you install three host subsystems for redundant protection.

The AC power supplies in EX9208 switches are hot-insertable and hot-removable field-replaceable units (FRUs). You can install up to four AC power supplies in an EX9208 switch. Power supplies are installed in the rear of the chassis in slots through (left to right).
Each power supply has its own fan and is cooled by its own internal cooling system. EX9208 switches support 2520 W AC power supply. The AC power supply supports both the low-voltage line (100–120 VAC) and the high-voltage line (200–240 VAC) AC power configurations.
Chapter 4: Power Supplies In the low-line (100–120 V) AC power configuration, the EX9208 switch contains three or four AC power supplies, located horizontally at the rear of the chassis in slots PEM0 through (left to right). Each AC power supply provides power to all components PEM3 in the switch.
Power Requirements for EX9200 Switch Components on page 91 DC Power Supply in an EX9208 Switch An EX9208 switch is configurable with two or four DC power supplies. The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the switch components, depending on their voltage requirements.
The DC power supplies in EX9000 switches are hot-insertable and hot-removable field-replaceable units (FRUs). You can install either two or four DC power supplies in an EX9208 switch. Power supplies are installed in the rear of the chassis in slots through (left to right).
