Make sure not to use the cross-over cable you were just using. Test the connection to

the RMC by pinging its address from any other computer on the network.

NOTE:

It is recommended that you change your password for security reasons. If you

are unable to connect to the RMC card across your network, make sure the

network connection at the switch for your RMC is able to pass 10Mbps traffic.

Resetting the RMC IP Settings to the Factory Defaults

To reset the IP address on an RMC to the factory default, do the following:

1. Shut down power on all blades in the primary R4200 chassis that houses the

RMC.

2. Remove the AC power cord from the back of the primary R4200 chassis.

3. Remove the Ethernet cable from the RS485 OUT port on the back of the primary

R4200 chassis, if one is connected.

4. Plug the Factory Default Jumper cable (provided with your R4200 chassis in the

Chassis accessory kit) into the RS485 OUT port on the back of the primary R4200

chassis.

5. Plug the AC cable back into the R4200 chassis and wait at least 15 seconds.

6. Remove the Factory Default Jumper cable.

7. Reattach the Ethernet cable to the RS485 OUT port on the back of the primary

R4200 chassis, if one was previously connected.

8. Power the blades back up in the primary R4200 chassis (if desired).

The RMC network controller is reset to the factory default settings, with an IP address of

192.168.1.251. Resetting the RMC to its factory defaults and connecting to it with a

laptop computer using a crossover cable is a helpful troubleshooting technique.
