What to Consider
The following bullets summarize information about using the Appliance Manager or Orchestrator when
replacing an appliance in an already deployed network:
• If you’ve made a backup of the appliance configuration, you’ll be able to restore it to the new
appliance. If not, you must manually configure the new appliance.
To manually configure the appliance, refer to the following user documents:
• Silver Peak Appliance Manager Operator’s Guide [200030-001]
• Silver Peak Unity Orchestrator User’s Guide [200095-001]
• If you’re replacing a 4-port appliance and want to restore the backup configuration, then make
sure that the new appliance is also a 4-port appliance.
System Replacement Procedure
1 Before removing the installed appliance, look at its configuration and write down the mgmt0 IP
addresses / netmask
and mgmt0 next-hop IP address.
2 If you haven’t backed up the configuration, do it now, using either the Appliance Manager or the
Orchestrator.
• When Access Manager creates a backup, the destination is the appliance itself. From there, you
can download it to your computer. So, make sure you have a copy outside of the appliance.
• The Orchestrator backs up appliances to the Orchestrator database.
3 Power down, disconnect, and remove the old appliance.
4 Physically install the new [replacement] appliance.
If you need to review rack mount instructions, refer to Silver Peak’s User Documentation web page.
5 Using the appropriate instructions, cable the appliance and configure the new appliance, as directed.
• For NX appliances, refer to the NX Series Quick Start Guide [PN 200257-001].
• For EdgeConnect appliances, refer to the Unity EdgeConnect Quick Start Guide
[PN 200907-001].
6 Make sure that the software revision in the new appliance is the same as in the replaced appliance:
• If the previous appliance was at a higher software revision, upgrade the new appliance to that
revision.
• If the previous appliance was at a lower software revision, call Customer Support for assistance.
7 Restore the backup configuration to the new appliance.
