Verifying the Status of the VCStack Feature

Before cabling the QSFP+ transceivers you should test the switches to
determine whether the VCStack feature is enabled or disabled, and enable
it on any units where it is disabled. The default setting for the feature is
enabled, so the feature should already be activated on new switches. But
on switches that were previously used as stand-alone units, the feature is
probably disabled and needs to be enabled.
Testing the status of VCStack is simple. You power on a switch, wait two
minutes, and examine the ID LED. If it is displaying a number from 1 to 8,
VCStack is already enabled on a switch. If the LED displays the number 0,
the feature is disabled and needs to be enabled. The default ID number is
1.
Before powering on the switch, review the information in "Power
Specifications" on page 132 for the power specifications of the switches.
