[. . . ] To reconnect the T640 router, initiate a change in mastership to the backup Routing Engine in the TX Matrix router, or replace the failed Routing Engine in the T640 router and switch mastership to it. (The replacement Routing Engine must be running the same software release as the master Routing Engine in the TX Matrix router. ) · · · If the on-loss-of-keepalives statement is not included at the [edit chassis redundancy failure] hierarchy level, consider the following: · If you initiate a change in mastership to the backup Routing Engine in the TX Matrix router, all T640 routers are logically disconnected from the TX Matrix router. To reconnect the T640 routers, switch mastership of all master Routing Engines in the T640 routers to their backup Routing Engines. If you initiate a change in mastership to a backup Routing Engine in a T640 router, the T640 router is logically disconnected from the TX Matrix router. To reconnect the T640 router, switch mastership of the new master Routing Engine in the T640 router back to the original master Routing Engine. · If you run the same Junos OS release on all master and backup Routing Engines in the routing matrix, a change in mastership to any backup Routing Engine in the routing matrix does not cause a change in mastership in any other chassis in the routing matrix. Configuration Groups Configuration groups allow you to create a group containing configuration statements (by including the groups statement) and to direct the inheritance of that group's statements in the rest of the configuration. The configuration groups offer a simple way to establish hostnames, management interfaces, and default routes. You can also specify two special group names--re0 and re1. These two special group names apply to the Routing Engines in slots 0 and 1 of the TX Matrix router. In addition, the TX Matrix router supports group names for the Routing Engines in each T640 router in the following formats: lcclcc-number-re0 146 Copyright © 2010, Juniper Networks, Inc. Chapter 17: Configuring Junos OS lcclcc-number-re1 lcc-number identifies the T640 router and can be from 0 through 3. For example, to configure Routing Engine 1 properties for lcc3, you include statements at the [edit groups lcc3-re1] hierarchy level. You must include the apply-groups statement in the configuration for all special groups, including re0 and re1. Providing special group names for all Routing Engines in the routing matrix allows you to configure the individual Routing Engines in each T640 router differently. Parameters that are not configured at the groups hierarchy level apply to all Routing Engines in the routing matrix. For more information about configuring the TX Matrix router, see"Performing the Initial Software Configuration for the TX Matrix Router" on page 142 and the Junos OS configuration guides. PIC MAC Addresses When you integrate a T640 router into a routing matrix, the PIC media access control (MAC) addresses for the T640 router are derived from a pool of MAC addresses maintained by the TX Matrix router. This means the PIC MAC addresses used in the formerly standalone T640 router are changed after the T640 router is integrated into a routing matrix. To determine the newly assigned MAC address for an interface on a PIC in an integrated T640 router, issue the show interfaces interface-name command. TX Matrix Interface Names Overview · · SCC and LCC Interfaces on page 147 FPC Interfaces on page 148 SCC and LCC Interfaces In certain statements and commands in the CLI, you refer to the TX Matrix chassis as scc and to a T640 chassis as lcc. You can configure the TX Matrix chassis and T640 chassis by including statements at the [edit chassis] and [edit chassis lcc lcc-number] hierarchy levels, where lcc-number is the chassis identifier (ID) of the T640 router. Operational commands that reference chassis hardware components--such as SIBs, FPCs, and PICs--require you to specify either scc or lcc, followed by the chassis ID. For example, to display a list of all hardware components in T640 2 (lcc 2), issue the show chassis hardware command as follows: user@host> show chassis hardware lcc 2 lcc2-re0: -------------------------------------------------------------------------Hardware inventory: Item Version Part number Serial number Description Chassis 65745 T640 Midplane REV 03 710-005608 RA1400 T640 Backplane FPM GBUS REV 09 710-002901 RA3317 T640 FPM Board FPM Display REV 05 710-002897 RA3249 FPM Display CIP REV 06 710-002895 HS0716 T-series CIP Copyright © 2010, Juniper Networks, Inc. 147 TX Matrix Hardware Guide PEM 0 PEM 1 SCG 0 Routing Engine 0 Routing Engine 1 . . .

For more information about operational mode commands, see the Junos OS command references. You configure a T640 chassis ID by setting a physical switch on each T-CB faceplate in the T640 router (see Figure 76 on page 162). [. . . ] If your site has previously experienced such problems, you might want to consult experts in electrical surge suppression and shielding. · Radio frequency interference--You can reduce or eliminate the emission of radio frequency interference (RFI) from your site wiring by using twisted-pair cable with a good distribution of grounding conductors. If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable. Electromagnetic compatibility--If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, you might want to seek expert advice. Strong sources of electromagnetic interference (EMI) can destroy the signal drivers and receivers in the router and conduct power surges over the lines into the equipment, resulting in an electrical hazard.
