Cannot find an Xgig1000 chassis using the discover button
in the port selection window
You are attempting to find a single Xgig1000 chassis or cascaded Xgig1000 chassis on the
network using the discovery operation in Xgig application software. You cannot discover
the Sync Group or the discovery process is taking an extremely long time.
The discovery operation may take an extremely long time if you have moved the Sync
Group to a different subnet. After moving an Xgig1000 chassis to another subnet, it is
recommended that you use the IP address the first time you attempt to discover it. This
prevents a potential Domain Name Server (DNS) issue.
•
Check to make sure you have the correct name of the Xgig1000 chassis.
•
If the Xgig1000 chassis cannot be found by name, use the IP address. For cascaded
chassis, the IP address of any of the chassis in the cascade should result in the Sync
Group being discovered.
•
Attempt to discover another Sync Group on the same subnet as the Sync Group you
are trying to discover. This operation should discover all Sync Groups on the same
subnet.
•
If you still cannot discover the Sync Group, use the Ping operation to see if the Sync
Group is on the network. If the Ping operation fails, see “Cannot ping the Xgig1000
chassis” on page 130. You can also connect to the console port on the Xgig1000
chassis to verify its IP address. See
“PATH 2: Setting Up the Xgig1000 Chassis with
a Static IP Address in a Non-DHCP Network” on page 87
, steps 1 through 8, for infor-
mation on getting the IP address through the console port.
Restarting the Xgig1000 Chassis with the Backup System Image
Using USB System Recovery Drive
If you cannot connect to the Xgig1000 chassis and access the system through any of the
administrations interfaces, such as the serial port, USB type A, or web interface, and you
have ruled out a network configuring or App kit issue, you may be able to reestablish oper-
ations by booting the Xgig1000 chassis with the alternate version of the Xgig1000 oper-
ating system on the USB recovery boot drive included in the chassis’ accessory kit.
You should use the USB system recovery drive only as a last resort when you cannot
connect to the system at all. If you can connect through the web interface but suspect a
corrupt system image, you should perform a system upgrade rather than use the USB
system recovery drive.
