Disabling and Reenabling IOAs

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.

Disabling and Reenabling IOAs
There is no no version.
See slot enable.
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 358.
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.
The default is enable.
On IOAs that support hot-swapping, issuing this command does not reboot the
line module. On unsupported IOAs, issuing this command reboots the line module
associated with the IOA, but does not enable the line module. Issue the slot
enable command to enable the line module. For a list of IOAs that support
hot-swapping, see Table 39 on page 358.
