3 Use the
set ip ip_address
command to assign a unique IP address to
the EME (RJ-45 type connector). Example:
CB9000> set ip ip_address 195.36.58.27 ethernet_port
4 Use the
set ip subnet_mask
command to assign a subnet mask to the
EME.
For example, to set the subnet mask for a class B device, without
subnetworks, enter a command similar to the following:
CB9000> set ip subnet_mask 255.255.0.0 ethernet_port
CAUTION: The default subnet mask is ff.00.00.00. In networks in which
the IP addresses begin with 151, the default subnet mask may conflict
with internally reserved addresses. To avoid this situation, create the
subnet mask before you set the corresponding IP address.
5 Log out from your terminal session.
6 Connect your EME’s 10BASE-T port to the network.
7 Use Telnet software to connect the system. Enter the system IP address in
the appropriate field in the software interface.
8 Log in to the EME and manage the system as appropriate.
The EME supports up to four incoming Telnet sessions.
You cannot use Telnet to connect to an EME if the EME is in standby
mode. You can connect an EME in standby mode to the network to
provide redundancy only.
CAUTION: Do not change the IP address of an EME that is already up
and running from an in-band network connection. Doing so will
terminate the session.
Connecting to
Remote Devices
The EME features a Telnet service for your convenience. To log in to
another network device from an EME session, follow these steps:
1 Verify that you are logged in to the EME through a serial port.
You can enter the EME
telnet
command only if you are logged in
through a serial port (RS-232 port).
2 Enter the telnet command and Specify the IP address of the remote
device. Example:
CB9000> telnet 192.34.67.101
You can open a connection only with devices that support the Telnet
protocol.
