Ringdale Minit 5250E - Manual (Page 34)

Copyright  2006 Ringdale User Manual, 62-400310001 Page 34
PROBLEM: Tried to connect the MinIT 5250E and it does not connect.
When you try to ping it fails.
CAUSE: You may have a problem with your router(s), bridge(s), or hub(s).
ACTION: Verify that the IP Address of the AS/400 is on the same subnet as the MinIT 5250E.
The Subnet Masks must be the same. Address bits that are not 0, need to be the same. Must
be on the same physical network.
First, ping the MinIT 5250E from the AS/400:
a) Go to any command line, where it says:
Selection or command
===>
b) Type PING '###.###.###.###' (where ###.###.###.### is the IP address
that you are trying to reach, enclosed in single quotes)
c) You will get a message: "Verifying connection to host system
###.###.###.###"
d) Put your cursor on that message and ROLL UP (which is the Page Down key in
some of the better emulation packages).
e) If it says: " PING reply 1 from ###.###.###.### took 59 ms. 256 bytes. TTL
128"
f) Then roll up again to check the next five. At the end it should say: "Connection
verification statistics: 5 of 5 successful (100 %)."
If it says "Unknown Host" or "No response from host within 1 seconds for connection
verification 1." well obviously you have a network problem to resolve.
CAUSE: Different subnet masks, different physical network. You may have a problem with
your router(s), bridge(s), or hub(s).
SOLUTION: If you can ping one way, but not the other, this is probably a router problem. If a
router table believes that a device is not on the network, it may misroute packets. Restart all
routers and bridges.
If the IP address and subnet masks are logically on the same network, but you still cannot
ping, then there may be a physical break in the networks. If the subnet for the AS/400 is not
the same as the subnet for the MinIT 5250E Workstation, they are on different supernets and
would need a router to connect.
Check your hubs. Try pinging other devices to see what devices you can reach, and what the
AS/400 can reach, to get a clue where the problem is. Look at the lights.
You must be able to ping the AS/400, and the AS/400 must be able to ping the MinIT 5250E.
