Table 8. SAN192C-6 Crossbar Modules LEDs

Status
Locater ID
The crossbar fabric switching modules are located behind the fan modules in the chassis, the LEDs on
the crossbar fabric switching module are not easily visible from the back of the chassis. So, the crossbar
fabric switching module status LEDs are provided on the fan modules as well. Each fan module covers two
crossbar fabric switching modules, the status LEDs for two crossbar fabric modules are present on each
fan module. If the fan module is removed, the status and locator LEDs on the crossbar fabric switching
modules will be visible.
When a crossbar fabric switching module needs to be located, the locator LED of the corresponding fan
module must be activated, followed by the locator LED of fabric module, using the CLIs locator-led
fan <fan module number> and locator-led xbar <xbar slot number>. For example, to
