Removing and Installing DRAM Modules

The DRAM installed on the Routing Engine provides storage for the routing and
forwarding tables and for other Routing Engine processes. The design of the
Routing Engine allows you to modify the DRAM configuration by adding DIMM
memory modules to the Routing Engine board, or removing DIMMs from the
board. The Routing Engine contains one or two 168-pin DIMMs.
To modify the DRAM configuration, use the following procedures:

Removing a DRAM Module

NOTE: Depending on your configuration, the Services Router might have an empty
DRAM slot. If you are adding a single DIMM to the DRAM configuration, proceed
directly to the next section, "Installing a DRAM Module" on page 531.
Gently grasp the USB drive and slide it out of the USB port.
Place the USB drive on the antistatic mat or in the electrostatic bag.
.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to the ESD point on the chassis, or to an outside ESD point if
the router is disconnected from earth ground. For more information about
ESD, see "Preventing Electrostatic Discharge Damage" on page 567.
Orient the USB drive with the USB port on the front panel of the router.
Insert the USB drive into the USB port. If the USB drive does not easily
slide into the port, it might not be oriented correctly. Turn the USB drive
upside-down and try again.
To configure the USB drive with the
"Configuring Boot Devices with the CLI" on page 508.
