54 SAN16M-R SAN Router Installation And Service Manual
Meaning and solution
This usually indicates that the connection is down for that particular port.
• The GE ports may display red if the cable is not plugged in securely. Check both to
make sure that they have clicked into place.
• Check cables for dents and tears, and make sure no large or sharp objects are on
top of the cables (especially the GE cable).
IP addresses of 224.x.x.x and above are Class D or Class E addresses that are
specifically reserved for multicast addresses or for future use. Set the SAN Router
manager port IP address below 224.x.x.x to solve the problem.
The SAN Router does not yet have a valid inband IP address. Use the Inband Address
Configuration dialog box (Configuration >System >Inband Address) to set the inband
address.
• A TFTP server must be running on a server that the SAN Router can connect to
through either the management port or a GE port. The TFTP protocol is not FTP.
• File names and paths are critical. Try to move the firmware to the same directory
on the servers where the TFTP server is located and use the name of the file with
the new path in the dialog box. The path that you enter in Element Manager is
always relative to the TFTP server's root directory.
• Try pinging the IP address of the management port for out-of-band management or
the SAN Router Inband IP address for inband management from the TFTP server
(example: ping 192.168.2.170).
• Check both iFCP ports and make sure you have link lights between the port and
the SAN Router/GE switch on either side. Ping across the link from local to the
remote SAN Router.
• Check in the Element Manager to make sure that each SAN Router has a unique
mSAN ID (Configuration>iFCP>Setup) and that the SAN Router has been reset
since this was changed.
• Check in the Element Manager to make sure that the iFCP port IP addresses are
on the same subnet or that the next hop router address is the correct next
hop/gateway.
• Check in the Element Manager to make sure that the Zone IDs are the same for the
mutually exported zones (Configuration>iFCP>Remote Connections).
• Check in the Element Manager to make sure that the remote SAN Router status is
up by going to: Configuration>iFCP>Remote Connections and checking the Status
column for the SAN Router in question. It should say "Up."
