See Figure 14 on page 31 and
a USB memory card that loads the Junos OS.
NOTE:
In EX9214 switches, you must install an RE module only in the SF modules
installed in slots 7 and 8 labeled
If you have installed only one RE module, you must power off the switch
before removing the RE module.
A base-configuration EX9204, EX9208, or EX9214 switch has only one RE module. See
EX9204 Switch Configurations, EX9208 Switch Configurations, and
Configurations" on page 8. You can add a second RE module to the configuration for
redundancy.
NOTE: We recommend that you install two RE modules in EX9204, EX9208,
and EX9214 switches for redundancy.
The RE module performs the following functions:
Provides switching functionality to the switch through the switching plane
Powers the line cards on and off
Controls system resets and the boot sequence for the switch
Monitors and controls the fan speed, power status for various chassis components,
and craft interface LEDs
The switch ships with the RE modules preinstalled. There are two copies of the software:
One copy on the solid-state drive (SSD) in the RE module.
One copy on a USB flash drive that can be inserted into the slot on the RE module
faceplate.
The RE module boots from the storage media in the following order: the USB device (if
present), then the SSD, and finally the LAN.
NOTE: Starting with Junos OS Release 17.1R1, EX9200 switches support the
EX9200-RE2 module. The EX9200-RE2 module supports virtual machine
(VM) architecture in an EX9200 switch. Only the EX9200-SF2 module
supports the EX9200-RE2 module. You cannot form a Virtual Chassis using
an EX9200 switch with an EX9200-RE2 module installed in it.
CAUTION: The EX9200-RE module and the EX9200-RE2 module are not
interoperable. Do not install both the RE modules in the same switch chassis.
