Specify neither the primary-srp nor the standby-srp keyword to stop operation on
both SRP modules.
Specify the keyword primary-srp to stop operation on the primary SRP module only.
This action causes the redundant SRP module to assume the primary role.
Specify the keyword standby-srp to stop operation on the redundant SRP module
only.
If you do not specify the force keyword, the procedure fails if:
The SRP modules are in certain states, such as during a synchronization. In these
cases, the router will display a message that indicates that the procedure cannot
currently be performed and the reason why. However, if the SRP modules are in
other states that could lead to a loss of configuration data or NVS corruption, the
router displays a message that explains the state of the SRP modules and asks
you to confirm (enter yes or no) whether you want to proceed.
The SRP modules are in any state that could lead to loss of configuration data or
NVS corruption, and the router will display a message that explains why the
command failed.
In Boot mode, you cannot issue any keywords with this command.
When the high availability state is active or pending, this command ensures that the
router configuration, up to when you issued the halt command, is mirrored to the
standby SRP.
When you issue this command, the router prompts you for a confirmation before the
procedure starts.
Remove or power down the SRP module within 2 minutes of executing the halt
command. Otherwise, the SRP module will automatically reboot.

host1#halt
host1#halt primary-srp
host1#halt standby-srp force

You can install line modules in slots previously occupied by different types of line modules.
For example, on the ERX1440 router, you can replace a GE-2 line module and a GE-2 SFP
I/O module in a slot that previously contained an OCx/STMx/DS3-ATM line module and
an OC3-4 I/O module.
When you configure a line module and an I/O module or IOAs, the router stores the
configuration in NVS. In some cases, you must erase the interface configuration on the
slot and reconfigure it after you have installed the new line module. However, some line
