You can use the steps in this thread on the documents tab to get access to the setup page to change the IP addresses  [URL]  With this being a CX400, i am sure that the default ip addresses are still on the SP.  That doc will get you into the array so you can assign new ones as well as destroy any domain security and setup new users.  you need a normal serail cable to access it.  I dont think it is a special cable.  I cant remember the terminal connection details but i think it might be 56800, 8, N, 1, off
Hi, I am a new user of EMC product and a new comer here, so please forgive me if I ask at the wrong place.   Some background information: My lab recently got a set of EMC CLARiiON CX400 FC fisk arrays (including a UPS, a Storage Processor(?) and a DAE2 FC unit). It is connected to an HP-UX 11i server via fiber to expand the server's disk capacity. It's all cabled and powered. I will need to install some 3rd party applcation software on the server to leverage the newly added capacity. According to the setup manual from the 3rd party vendor, I need to assign two IP addresses to the CX400 SPA and SPB each. They to do this is to launch a browser and access to [URL] where x.x.x.x is the SPA's or SPB's IP address, once I open up the web page with that address, then I can login and update the IP address information with real IPs from my lab environment.  Now here are my questions: 1) what is the default IP addresses for CX400 SPA or SPB modules? 2) what is the default admin login and password I can use to update the IPs once I can open the setup webpage? 3) Is there a way I can directly access the SPA/SPB via the serial port and update its IP information? If so, can I find some document telling how to do it? (do I need special serial cable for the 9-pin serial port at the back of SPA/SPB modules? what's the terminal settings I should use in order to access it via hyper-term? etc...)  I have found some hardware related document from EMC website, but so far I didn't see anything talking about these settings. So any advice from you will be appreciated.  Thanks in advance,  -Liang
