My portserver 16 is rebooting itself, How do I check it's log to see what is happening ?

There has to be a log on my portserver 16 devices but I don’t see how to access it. One of them is rebooting itself and I’m hoping it’s log will shed light on the problem. The RANs are connect to AIX servers running RealPort driver.

From the command line:

#> display error

However, if this is an IBM branded unit, you will need to contact IBM for support.
