12.1.2 Access the Command-Line Interface (CLI) of a Gateway Switch
With power applied, you can access the CLI of a gateway switch in your Exalogic
machine.
The number of gateway switches in your Exalogic machine depends on your
purchased Exalogic machine rack configuration. You must access the command-line
interfaces of these gateway switches individually.
For example, to access the CLI of a gateway switch, complete the following steps:
1. If you are using a network management port, begin network communication with
the CLI using the ssh command and the host name configured for the gateway
switch:
% ssh -l root gateway-name
root@gateway-name's password: password
#
where gateway-name is the host name configured for the gateway switch.
If you do not see this output or prompt, there is a problem with the network
communication, host name, or CLI.
2. If you are using a USB management port, begin serial communication with the
CLI as follows:
a. Connect a serial terminal, terminal server, or workstation with a TIP
connection to the USB-to-serial adapter. Configure the terminal or terminal
emulator with these settings:
115200 baud, 8 bits, No parity, 1 Stop bit, and No handshaking
b. Press the Return or Enter key on the serial device several times to synchronize
the connection. You might see text similar to the following:
…
CentOS release 5.2 (Final)
Kernel 2.6.27.13-nm2 on an i686
gateway-name login: root
Password: password
#
where gateway-name is the host name assigned to the gateway switch.
If you do not see this output or prompt, there is a problem with the network
communication, host name, or command-line interface (CLI).
3.
Note:
Repeat these steps to access the CLI for the other gateway switches in your
Exalogic machine.
12.1.3 Verify the Status of a Gateway Switch
For each gateway switch, you can check the status of the CLI, power supplies, fans,
and switch chip. Verify that the voltage and temperature values of the gateway switch
are within specification:
