Basic Celerra questions

Greetings from Detroit Michigan!

I just stated at a new job and one of the systems I have inherited is a Celerra.  It appears to be composed of an NS-42G and a 1U standard server.  It appears to be hanging off of a CX3-40 here.

My questions:

1) does this sound like a typical Celerra arrangement

2) is there any way to health check the Celerra

3) how does one manage the Celerra - it appears that the only way into the Celerra is via SSH - no web server of any sort (apache, tomcat, etc) is running.

4) there is a folder on the Celerra called /nas.  It contains 4 dead links (invalid destination).  Is this normal?

5) if need be, is there a way to reload the OS for the Celerra?

Thanks!
