Record the location information for your enclosures.
If you have only one system, it is relatively easy to identify the enclosures that make up the system. Identification becomes more difficult when you have multiple systems in your data center and multiple systems in the same rack.
The enclosure identifier that is displayed on the front of the display is unique within a system. However, the identifiers can be repeated between different systems. Do not rely solely on this identifier.
For each system, record the location of the control enclosure and the location of any expansion enclosures. It is useful to label the enclosures themselves with the system name and the management IP addresses.
