DHCTs with Single LED Indicators
DHCTs with only POWER LED indicators display the codes associated with
downloading, installing, and booting into the SARA as a series of flashing lights
using the POWER LED indicator light on the front panel.
Note: You must stage DHCTs with only POWER LED indicators using the CVT
download method.
The following table shows an example of a CVT download sequence of front panel
LED displays that appear after AC power is applied to the DHCT.
