3.5 Verifying Proper Power-Up of the Ethernet Interface after
Configuration
After configuring the interface as described in Chapter 4, turn power OFF to the CPU for 3–5 seconds, then turn
the power back ON. This starts a series of diagnostic tests. The EOK LED will blink indicating the progress of
power-up.
The Ethernet LEDs will have the following pattern upon successful power-up. At this time the Ethernet Interface
is fully operational and on-line.
LED Ethernet Interface Online
EOK On
LAN On, Off, or blinking, depending on network activity
STAT On
If a problem is detected during power-up, the Ethernet Interface may not transition directly to the operational
state. If the Interface does not transition to operational, refer to “Diagnostics,” Chapter 12 for corrective action.
3.6 Pinging TCP/IP Ethernet Interfaces on the Network
PING (Packet InterNet Grouper) is the name of a program used on TCP/IP networks to test reachability of
destinations by sending them an ICMP echo request message and waiting for a reply. Most nodes on TCP/IP
networks, including the PACSystems Ethernet Interface, implement a PING command.
You should ping each installed Ethernet Interface. When the Ethernet Interface responds to the ping, it verifies
that the interface is operational and configured properly. Specifically, it verifies that acceptable TCP/IP
configuration information has been downloaded to the Interface.
For configuration details, including setting an initial IP address, refer to Chapter 4.
Pinging the Ethernet Interface from a UNIX Host or Computer
Running TCP/IP Software
A ping command can be executed from a UNIX host or computer running TCP/IP (most TCP/IP communications
software provides a ping command) or from another Ethernet Interface. When using a computer or UNIX host,
you can refer to the documentation for the ping command, but in general all that is required is the IP address of
the remote host as a parameter to the ping command. For example, at the command prompt type:
ping 10.0.0.1
