2. Watch LEDs to verify proper operation.
The diagnostic self test LED Behavior is as follows:
• Initially, all the status, LED Mode and port LEDs are on for most of the duration of the test.
• Most of the LEDs go off and then may come on again during phases of the self test. For the
duration of the self test, the Test LED stays on.
If the ports are connected to active network devices, the LEDs behave according to the LED
Mode selected. In the default view mode (Link), the LEDs should be on.
If the ports are not connected to active network devices, the LEDs will stay off.
Powering on the control point PC
Use the following procedure to power on K2 SAN’s control point PC and verify proper operation
during power up of the system.
1. Power up and log on to the PC using standard Windows procedures.
2. Start and log on to NetCentral.
3. NetCentral reports devices as offline. As each device of the K2 SAN is powered on, check
NetCentral to verify the device’s status.
Failover behaviors
If a fault occurs and one of the failover mechanisms is triggered, an online redundant iSCSI K2
SAN behaves as explained in the following sections.
The diagrams that follow are representative of a generic redundant K2 SAN. Some details, such as
the number of media connections, might not be the same as your K2 SAN. These diagrams illustrate
the media (iSCSI) and control paths as they interact with the redundant K2 Media Servers in their
role of media file system/metadata server and iSCSI bridge. Interactions of FTP traffic and/or paths
involving K2 Media Servers with other roles are not illustrated.
