T1600 Routing Engine Description
The Routing Engine is an Intel-based Peripheral Component Interconnect (PCI) platform that runs Junos OS. Software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the T1600 Core Router, control the T1600 router interfaces, control some chassis components, and provide the interface for system management and user access to the router.
You can install one or two Routing Engines in the router. The Routing Engines install into the upper rear of the chassis in the slots labeled RE0 and RE1. Each Routing Engine requires a control board to be installed in the adjacent slot. RE0 installs below CB0, and RE1 installs above CB1. A Routing Engine does not power up without a control board present in the adjacent slot.
If two Routing Engines are installed, one functions as the master and the other acts as the backup. If the master Routing Engine fails or is removed and the backup is configured appropriately, the backup takes over as the master. If the host system is redundant, the backup Routing Engine is hot-removable and hot-insertable, but the master Routing Engine is hot-pluggable. A Routing Engine that is not redundant requires that you power down the router before replacement.
 | Note: For specific information about Routing Engine components (for example, the amount of DRAM), issue the show chassis routing-engine command. |
The ports for connecting the Routing Engine to external management devices are located on the Connector Interface Panel (CIP).
| Note: If two Routing Engines are installed, they must both be the same hardware model. |
The T1600 router supports these Routing Engines:
- RE-600 is supported in Junos OS Release 8.5 and later.
- RE-1600 is supported in Junos OS Release 8.5 and later.
- RE-2000 is supported in Junos OS Release 8.5 and later.
- RE-C1800 is supported in Junos OS Release 9.6R2 and later.
Note: The RE-C1800 is required for connection to a TX Matrix Plus router.
