Figure 13: Routing Engine 1600 (RE-1600)

Each RE-1600 (shown in Figure 13 on page 29) consists of the following components:
CPU—Runs Junos OS to maintain the router's routing tables and routing protocols. It
has a Pentium-class processor.
SDRAM—Provides storage for the routing and forwarding tables and for other Routing
Engine processes.
CompactFlash card—Provides primary storage for software images, configuration files,
and microcode. The CompactFlash card is inaccessible from outside the router.
Hard disk—Provides secondary storage for log files, memory dumps, and rebooting the
system if the CompactFlash card fails.
EEPROM—Stores the serial number of the Routing Engine.
Interfaces for out-of-band management—Provide information about Routing Engine
status to devices (console, laptop, or terminal server) connected to the Routing Engine
ports located on the CIP.
The faceplate of the RE-1600 contains the following:
Two PC Card slots—Accept removable PC Cards, which store software images for
system upgrades.
Each PC card slot accepts a Type I PC Card, as defined in the PC Card Standard
published by the Personal Computer Memory Card International Association (PCMCIA).
The TX Matrix router is shipped with a PC Card that contains Junos OS. The PC Card
can be used to copy Junos OS from the PC Card onto the Routing Engine. You can also
copy Junos OS from the Routing Engine onto a PC Card, for example, to create a backup
copy of upgrade software that you have obtained from Juniper Networks. Instructions
for copying software to a PC Card are available at the Juniper Networks Support Web
site ( http://www.juniper.net/support/
Support Center, then to the download page for Junos OS.
NOTE: The software on a PC Card is loaded only onto the Routing Engine
into which the PC Card is inserted. It is not automatically copied to the
other Routing Engine.
