Test a Connection With PING
When you set up a new connection or need to troubleshoot an existing connection to another
device, you can send a PING to the specific IP address for that device. Use the PING Generation
screen to test the connection. To set up and send a PING, follow these steps:
1. At the Domain Management Module menu, type 3 , "Ping Generation," and press <Enter>.
2. At the PING Generation screen, to set the PING Address, type 1 and press <Enter>, then type
the IP address to PING and press <Enter>.
3. To set the number of times to send a PING, type 2 , "Ping Count," and press <Enter>, then
type a number from 1 to 256, or type 0 to PING continuously every second, press <Enter>.
4. To start to PING, type 3 ; the display includes Time to Live (TTL) for each packet.
A good connection appears similar to this with all requests returned:

Update Software
Each module in the Universal Chassis System has two flash memory banks that store software:
• The Active Flash Memory holds the software currently in use
• The Inactive Flash Memory holds the new software from a download or the older version of
software
Software is downloaded to the inactive region to avoid disrupting service. Resetting the module
and swapping banks does not affect module operation and is transparent to user traffic.
