Connecting to a Routing Matrix with a TX Matrix Router

• Console/AUX—Asynchronous access via the console and auxiliary ports on the TX Matrix router or T640 router Connector Interface Panel (CIP).
• Management Ethernet—Telnet access via the Fast Ethernet ports on the TX Matrix router or T640 router CIPs.
• CLI login from one Routing Engine to another—All Routing Engines in the routing matrix with a TX Matrix router are connected to their respective control boards, which in turn are connected to the CIP on the TX Matrix router (see the TX Matrix Router Hardware Guide for more details). After you log in to one Routing Engine, you can connect to another Routing Engine as follows:
  user@router> request routing-engine login ?

  Possible completions:
    backup               Log in to backup RE
    lcc                  Log in to LCC (0..3)
    master               Log in to master RE
    other-routing-engine  Log in to the other Routing Engine
    re0                  Log in to RE0
    re1                  Log in to RE1
  
  user@router>  request routing-engine login lcc ?
  Possible completions:
    <lcc>                Log in to LCC (0..3)
  
  user@router>  request routing-engine login lcc 0 ?
  Possible completions:
    backup               Log in to backup RE
    master               Log in to master RE
    re0                  Log in to RE0
    re1                  Log in to RE1
  

  Note: Because the routing matrix appears as a single router, we recommend that you access the master Routing Engine of the TX Matrix router to perform all configuration tasks for the routing matrix. Under normal operating conditions, you do not need to access or configure the T640 router directly. If you access a Routing Engine on a T640 router, the following warning is displayed: user@router> request routing-engine login lcc 0 re0 --- JUNOS 7.0-20040625.1 built 2004-06-25 19:51:38 UTC % % cli warning: This chassis is a Line Card Chassis (LCC) in a multichassis system. warning: Use of interactive commands should be limited to debugging. warning: Normal CLI access is provided by the Switch Card Chassis (SCC). warning: Use 'request routing-engine login scc' to log into the SCC.

To manage the backup Routing Engines on all components (for example, to upgrade Junos OS), log in to the TX Matrix router backup Routing Engine and perform the necessary operations.
