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
Juniper Edge Routing Switch E120
.......
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-10A-ADV enabled --- 10-1-0b1-6-A.rel 2d19h:29m:18s
3 --- --- --- --- --- ---
.......
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 or ES2 10G
ADV LM. Do not remove the ES2-S1 GE-8 IOA or the ES2-S1 Redund IOA.
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-10A-ADV enabled --- 10-1-0b1-6-A.rel 2d19h:29m:18s

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