Disabling And Reenabling Line Modules, Srp Modules, And Sfms - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

JUNOSe 11.1.x System Basics Configuration Guide
You can configure the E120 router with a 320 Gbps fabric by installing SRP 120
modules and SFM 120 modules, or SRP 320 modules and SFM 320 modules.
You can configure the E320 router with a 100 Gbps fabric by installing SRP 100
modules and SFM 100 modules. To achieve increased switch fabric capacity and
speed, you can configure the E320 router with a 320 Gbps fabric by installing SRP 320
modules and SFM 320 modules.
You can configure the SC and the fabric slices on the SRP modules separately. For
example, if you disable the fabric slice on the standby SRP module by using the slot
disable 7 fabric command, the SC on that SRP module is still enabled.
Redundancy is supported for SRP modules on the E120 and E320 routers. For more
information, see SRP Module Redundancy in JUNOSe Service Availability Guide.
SRP modules on the E120 and E320 routers have two slots for flash cards; other E
Series routers have only a single slot. Cards installed in the second slot can be used
only for core dump (.dmp) files. For more information, see "Managing Flash Cards
on SRP Modules" on page 378.
SRP modules on the E120 and E320 routers have a corresponding SRP IOA that
contains a Fast Ethernet management port. You can configure this port to access the
router from the CLI or SNMP. For more information, see "Managing the Ethernet
Port on the SRP Module" on page 402 .
For information about using high availability mode for stateful SRP switchover, see
"Managing Modules" on page 355.

Disabling and Reenabling Line Modules, SRP Modules, and SFMs

Disabling a line module, an SRP module, or an SFM has the same effect as removing
that module from a slot. A disabled module cannot operate, although its configuration
remains in NVS. For the module to operate, you must reenable it.

Disabling and Reenabling Line Modules, SRP Modules, and SFMs
Use to disable the module in the specified slot.
You can use this command to disable a module so that you can run diagnostic
tests on the module.
You cannot use this command on a standby SRP module.
If you specify a slot on the E120 or E320 router that contains an SRP module,
you disable the SC subsystem on that slot by default. You do not, however,
disable the fabric slice that resides on the slot.
Use the srp keyword to disable only the portion of the SC subsystem that
resides on a specified SRP module.
Use the fabric keyword to disable only the fabric slice that resides on the
specified SRP module.
If you specify a slot that contains a line module, you disable only the line module;
you do not disable the line module and the I/O modules and IOAs associated
