Crs Not Starting _ private Interconnect Down

Question

Hello All,
I Have Installed 2 node 10g R2(10.2.0.1) RAC on Solaris 10 T2000 Machines. Yesterday my Second Node Crs gone down. I tried to start it but it didn't start. Then i checked that Private IP (interconnect) is not Pinging from both the node. But Node 1 was up and working so my Users Can Connect to It.
But Today morning I see that Crs on node 1aslo goes down .
Is this is problem of private interconnect.? My network guys are trying to up Private Interconnect.
If Private Interconnect is down, why node 1 goes down after few hours. i think private interconnect is for interconnect with node 2 but node 2 is down .
Previously My interconnect was connected with cross cables now i have asked them to connect them through switch.
Help me Out.
Regards,
Pankaj.

QUESTION
========
1.Will the database and the Clusterware need to be shutdown etc?
2.Will our ip addresses need to be reconfigured?
3.Are there any steps that need to be carried out before unplugging the CROSS CABLE
and after the interconnect is connected to the switch...?
ANSWER
======
1. Yes, you have to stop CRS on each node.
2. No, not required.Provided you are planning to use same ip addresses.
3. Steps:
a. Stop CRS on each node. "crsctl stop crs"
b. Replace the crossover cable with switch.
c. Start the CRS on each node. "crsctl start crs"
Even we are planning to do the same.Please share your experienceFollowed by the above answers from Customer Support, It went smooth, we stopped all the services, and with both the nodes reboot.
