Replacing a Line Module Without Erasing the Slot Configuration

Use this procedure when you are replacing an ES2 4G LM with an ES2 10G LM, or vice-versa. Both line modules must already be paired with an ES2-S1 GE-8 IOA or the ES2-S1 Redund IOA.

You can replace a single line module or all of the line modules in a redundancy group using this procedure.

Note: In some cases, the ES2 4G LM and ES2 10G LM support different system maximums and protocols. Before you replace an ES2 4G LM with an ES2 10G LM, make sure that:

  • The ES2 10G LM supports the features already configured on the slot for the ES2 4G LM.
  • The ES2 10G LM can support the existing system maximums configured on the ES2 4G LM.

If you have a configuration on the ES2 4G LM that is not supported on the ES2 10G LM, you must erase the configuration before replacing the line module. For more information, see Replacing a Line Module by Erasing the Slot Configuration .

To replace a line module without erasing the slot configuration:

  1. (Optional) If line module redundancy is configured for the slot, disable redundancy.
    host1(config)#redundancy lockout 1
  2. Disable the slot.
    host1(config)#slot disable 1
  3. After the line module has booted, issue the show version command to ensure that the status of the line module is disabled (admin). 
    host1#show version

    .......
    

    

                                                     running
slot  state   type    admin             spare    release     slot uptime
---- ------- ------- -------            ----- ------------- -------------
0      ---     ---     ---    ---        ---       ---
1    online  LM-10   disabled (admin)    ---  9-1-0b0-9.rel 1d08h:32m:29s
2    online  LM-10   enabled             ---  9-1-0b0-9.rel 1d08h:32m:24s
3      ---     ---     ---               ---       ---           ---
    

    

    .......
    

    

    4. 

  4. Remove the current line module and insert the new line
module without removing the IOA. 
    For example, remove the ES2 4G LM and insert the
new ES2 10G LM. Do not remove the ES2-S1 GE-8 IOA or the ES2-S1 Redund
IOA. 
    

    5. 

  5. After the new line module has booted, issue the show version command to ensure that the status of the
line module is disabled (mismatch).

    host1#show version
Juniper Edge Routing Switch E120
    

    

    .......
    

    

                                                     running
slot  state   type    admin             spare    release     slot uptime
---- ------- ------- -------            ----- ------------- -------------
0      ---     ---     ---    ---        ---       ---
1    online  LM-4    disabled (mismatch) ---  9-1-0b0-9.rel 1d08h:32m:29s
2    online  LM-10   enabled             ---  9-1-0b0-9.rel 1d08h:32m:24s
3      ---     ---     ---               ---       ---           ---
    

    

    .......
    

    

    6. 

  6. Issue the slot replace command
on the slot.

    

    host1(config)#slot replace 1 

    

    
    

    

    

    

    


    
Tip:
			If the line module is in a redundancy group and you did not
disable redundancy in Step 1, the system switches to the spare line
module. The system reloads both the replaced line module and the spare
line module when you issue the slot replace command.
    
    		

    

    

    

    

    7. 

  7. If you disabled redundancy for the slot in Step 1,
enable redundancy when the replacement line module has come online.

    

    host1(config)#no redundancy lockout 1 

    

    

    
    

    8. 

  8. (Optional) If the following settings were configured before
replacing the module, reconfigure the settings:
      

    1. Configure the Ethernet physical interface configuration
using an SNMP set request for entPhysicalAssetID and entPhysicalAlias.
      2. 

    2. Specify the threshold values for specific interface types
for the slot.

      

      host1(config)#resource if-type ip slot 1 threshold
