12. Tighten the pan head screws that secures the compact flash slot cover to the

rear of the chassis.

13. Plug the power cord into the power supply.

LED lights steadily.

Replacing USB Storage Devices

USB storage devices are optional components on J-series Services Routers. If installed,

a USB storage device provides secondary storage for the router. It can accommodate

software images, configuration files, and microcode. If the internal compact flash

fails on startup, and the external compact flash is not installed or fails, the router

boots from the USB storage device.

For information about configuring the USB storage device, see the JUNOS Software

Interfaces and Routing Configuration Guide.

NOTE: For a list of supported USB storage devices, see the JUNOS Software with

Enhanced Services Release Notes at http://www.juniper.net.

To remove and install a USB storage device, perform the following procedures:

■Removing the USB Storage Device on page 134

■Installing the USB Storage Device on page 135

Removing the USB Storage Device

NOTE: Depending on your configuration, the Services Router might not have a USB

storage device. If no USB storage device is installed, proceed directly to “Installing

the USB Storage Device” on page 135.

The USB storage device is installed into the USB port on the front panel of the Services

Router. To remove the USB storage device:
