Continue to Monitor the DHCT Sign-On Traffic 
Introduction 
With the signonCount interface displayed, continue to monitor the signonCount 
utility output to determine the health of your system before downloading the latest 
version of QPSK software to the next QPSK modulator. 
 
Monitoring the DHCT Sign-On Traffic 
To determine when it is safe to download the latest version of QPSK software to the 
next QPSK modulator, complete the following steps. 
1  Continue to monitor the DHCT sign-on traffic. Your system is healthy if the 
following conditions are true: 
 
The values in the Verified RcvdVerified Sent, and DAVIC Made columns 
are the same. 
 
The values in the Un-Config Rcvd and Un-Config Sent fields are 
approximately one fourth of the values in the DAVIC Made column. 
 
The values in the Threshold Exceeds Ver and Threshold Exceeds UCfg 
columns are zero. 
 
No QPSK modulators have rebooted. 
2  Is your system healthy? 
 
If yes, go to step 3. 
 
If no, call Cisco Services. Do not continue with these instructions. 
3  Wait approximately 15 minutes before resetting the next QPSK. Then, repeat the 
procedures in Download Software to the QPSK Modulators (on page 22) for 
each QPSK modulator you are upgrading. 
Important: After resetting each QPSK modulator, continue to monitor the DHCT 
sign on traffic. As each QPSK modulator reboots, notice that the values in the 
signonCount utility interface increases. This is to be expected. Also notice that as 
DHCTs sign on to the system, the values decrease, and the system returns to its 
healthy state. 
 
After downloading the QPSK software, continue to monitor the DHCT sign-
on traffic for 10 to 48 hours. It is not necessary to watch the sign-on traffic 
continuously, but you should check occasionally during this time to ensure 
that there are no problems. 
 
In the QPSK Reboots column of the signonCount Interface, you may notice 
that a QPSK modulator reboots automatically. If this occurs, wait 15 minutes 
before resetting (rebooting) the next QPSK.
