Logging in through the management Ethernet port of the OAP
module by using SSH or Telnet
To log in to the operating system of an OAP module through its management Ethernet port, you must first
configure the OAP module as the SSH server or Telnet server. To do so, follow these steps:
1. Switch to the CLI of the OAP module from the device, enable the SSH or Telnet server function, and
configure the accounts for SSH or Telnet logins.
2. Use a network cable to connect the management Ethernet port of the OAP module to the network.
3. Assign an IP address to the management Ethernet port of the OAP module, and make sure the SSH
or Telnet client (an H3C device or a PC that has the SSH or Telnet client software installed) and the
management Ethernet port can reach each other.
4. Establish an SSH or Telnet connection, entering the IP address of the management Ethernet port as
the server IP address.
After the connection is successfully established, you are logged in to the operating system of the OAP
module.
Logging in through the internal Ethernet interface on the OAP
module by using SSH or Telnet
When installed in the expansion slot of a device, an OAP module exchanges information with the device
through its two internal service interfaces: one serial interface and one fast Ethernet interface. The fast
Ethernet interface is used in this login mode.
To log in to the operating system of an OAP module through its internal Ethernet interface, you must first
configure the OAP module as the SSH or Telnet server. To do so, follow these steps:
1. Switch to the CLI of the OAP module from the device, enable the SSH or Telnet server function, and
configure the accounts for SSH or Telnet logins.
2. Assign an IP address to the fast Ethernet interface on the OAP module.
3. Use a network cable to connect an Ethernet port of the OAP module to the network.
4. Make sure the internal fast Ethernet interface of the OAP module and the PC can reach each other.
5. Run the SSH or Telnet client software on the PC and enter the IP address of the internal fast Ethernet
interface as the server IP address.
After the connection is successfully established, you are logged in to the operating system of the OAP
module.
Resetting OAP modules
CAUTION:
Before you reset an OAP module, close the operating system of the OAP module using the poweroff
command to prevent the data on the disk from getting lost.
To recover an OAP module from an error condition, reboot the module at the CLI or press the reset button
on the module. The device can still identify and control the OAP module after the reset.
