Replacing and Troubleshooting Hardware Components

Installing the USB Storage Device

To install the USB storage device:

NOTE: For a list

of supported USB storage devices, see the J-series Services Router

Release Notes at

http://www.juniper.net.

1. Attach an electrostatic discharge (ESD) grounding stra p to your bare wrist and

connect the str

ap to the ESD point on the chassis, or to an outside ESD point if

the router is disconnected from earth ground. For mo re i nformation about

ESD, see “Preventing Electrostatic Discharge Damage” on page 205.

2. OrienttheUSBstoragedevicewiththeUSBportonthefrontpaneloftherouter.

3. Insert the USB

storage device into the USB port. If the USB storage device does

not easily slide into the port, it might not be oriented co rrectly. Tu rn the USB

storage device upside -down and try again.

Removing and Installing DRAM Modules

The DRAM installed on the Routing Eng in e provides storage for the routing and

forwarding t

ables and for other Routing E ngine processes. Th e design of the

Routing Engin e allows you to mo di fy the DRAM configuration by adding DRAM

modules to the Routing Engine board, or removing DRAM modules from the board.

The DRAM modules are lo cated on the top of the Routing Eng ine, as shown in

Figure 45.

NOTE: Use on ly DRAM modules purchased through Juniper Networks specificall y

for your model. Also, DRAM modules are not always transferable across J-series

platforms.

You can use the same DRAM module in both the J4350 and J6350

Services Routers. However, do not use a DRAM from another J-series platform

in a J4350 or J6350 router.
