Reperform Initial Setup

Access the new CMC from the serial management port.
Log in, then invoke a reboot of the CMC:
```
# reboot
```
The CMC reboots.
When you see the following output, press any key to stop the boot process:
```
hit any key to stop autoboot
```
Type the following commands to set the respective parameters:
```
shmm1500 setenv m9_autostart y
shmm1500 setenv rc_ifconfig y
shmm1500 setenv start_rc2_daemons y
shmm1500 setenv rc2 /etc/rc.sun_m9
shmm1500 setenv start_mcm y
```
Note - Do not use “=” when setting the parameters, use a space “ “ instead. Using an equal sign has undesirable results.
Set the gateway IP address and the backup state IP address:
```
shmm1500 setenv gatewayip gateway_IP_address
shmm1500 setenv ipaddr backup_IP_address
```
where:
- gateway_IP_address is the IP address of the gateway.
- backup_IP_address is the backup state IP address of the CMC
  
  Note - Setting the backup state IP addresses of both CMCs to the same value causes a reallocation according to this rule: If the backup_IP_address is odd, then it is assigned to CMC1 and CMC0 is assigned backup_IP_address+1. If the backup_IP_address is even, then it is assigned to CMC0 and CMC1 is assigned backup_IP_address +1
Save the configuration:
```
shmm1500 saveenv 
```
Continue booting the switch:
```
shmm1500 boot
```
The switch boots.
Log in as the root user and set the IP address for the CMC:
```
# clia setlanconfig 1 3 active_IP_address
```
where active_IP_address is the active state IP address.

Note - Setting the active state IP addresses of both CMCs to the same value is permitted and does not cause conflict. Only one CMC can be in an active state, therefore only one host with the active_IP_address exists at any time. An advantage of identical active state IP addresses is that the network management console will always log into the active CMC.
Set the netmask for the CMC:
```
# clia setlanconfig 1 6 netmask
```
where netmask is the netmask. Typically, the netmask is 255.255.255.0. However, your network environment subnet might require a different netmask. Use a netmask number most appropriate to your environment.
Set the IP address for the CMC gateway:
```
# clia setlanconfig 1 12 gateway_IP_address
```
where gateway_IP_address is the IP address of the gateway set in Step 5.

Open a Telnet session and connect to the CMC by specifying the CMC’s network address.

For example:

% telnet 123.45.67.89 
Trying 123.45.67.89...
Connected to 123.45.67.89.
Escape character is ’^]’.
 
shmm1500 login:

Login as root using the root password.
```
shmm1500 login: root
Password: password
#
```
The # prompt is displayed.

Note - As shipped, the root password is not set and therefore not required. Press the Enter key when prompted for the password. Refer to the Sun Datacenter InfiniBand Switch 648 Administration Guide for instructions on how to set the root password.
