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
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 Rcvd, Verified Sent, and DAVIC Made columns
are the same.
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.
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.
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.

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.
