Cannot access the Chassis Viewer browser window. The browser window times out and Chassis Viewer will not come up.

Resolution / Workaround

1.Invalid IP Address entered for the chassis or spine modules via the console port. Use the showChassisIpAddr command to be sure the address has been set correctly.

2.If attempting to access the switch from a remote LAN, ensure that the default gateway/default route addresses are set correctly.

A.2.1.2

Symptoms

When viewing the IB fabric with the SilverStorm Fabric Viewer, no nodes are

seen.

Resolution / Workaround

1.Possibly a bad IB cable(s). Ensure that there is a Blue LED illuminated on the leaf module IB ports of the switch. Make sure that all devices (nodes) can be seen in the Fabric Viewer window.

2.Check the cables and connections subnet manager and the rest of the fabric.

3.The subnet manager may not be running on the IP address specified in Fabric Viewer. Check the IP address and make sure the subnet manager is in the Active state on that node. Depending on the configuration of that node, following a reboot the subnet manager may or may not restart.
