Disabling and Reenabling IOAs

adapter disable
adapter enable
348
host1(config)#slot enable 7
Example 3—Enables only the fabric slice on the SRP module in slot 7 (applies only to
E120 and E320 routers)
host1(config)#slot enable 7 fabric
There is no no version.
See slot enable.
Disabling an IOA on the E120 or E320 router has the same effect as removing that IOA
from a slot. A disabled IOA cannot operate, although its configuration remains in NVS.
To allow the IOA to operate, you must reenable it.
Use to disable the IOA in the specified IOA bay.
You can use this command to disable an IOA so that you can run diagnostic tests on
it.
On IOAs that support hot-swapping, issuing this command does not reboot the line
module. On unsupported IOAs, issuing this command does reboot the line module
associated with the IOA, but does not disable the line module. Issue the slot disable
command to disable the line module. For a list of IOAs that support hot-swapping, see
Table 39 on page 344.
When you issue the adapter disable command in a redundancy configuration, the line
module (primary or spare) currently associated with that IOA is rebooted. If the IOA is
protected by a line module redundancy group, an automatic line module redundancy
switchover or revert can be triggered by the line module reboot. To prevent undesired
line module redundancy actions, issue the redundancy lockout command for the
primary line module slot before issuing the adapter disable command. For more
information, see Line Module Redundancy in JunosE Services Availability Configuration
Guide.
In the software, adapter 0 identifies the right IOA bay (E120 router) and the upper IOA
bay (E320 router); adapter 1 identifies the left IOA bay (E120 router) and the lower IOA
bay (E320 router).
Example—Disables the IOA residing in the upper bay of slot 5 in an E320 router
host1(config)#adapter disable 5/0
There is no no version.
See adapter disable.
Use to enable the IOA in the specified IOA bay.
Enables you to restart the IOA that was installed in the slot.
