Chapter 8 Returning DHCTs and CableCARD Modules to Service

Check for Stranded IPPV Events and Clear NVM

This section contains procedures to prepare a DHCT for in-home use after it has
been returned from a subscriber's home. The procedures necessary for processing
field returns are listed as follows:
1 If your facility uses the Service Disconnect feature (Brick mode), place the DHCT
into Service Disconnect mode.
2 Check for stranded IPPV events and request collection of any stranded events
from a DHCT in a two-way staging area.
3 Activate the Staging Toolkit and clear the Non-Volatile Memory (NVM) menu
settings.
Note: Clearing the NVM does not remove stored purchases. You must connect
the DHCT to the network and poll it using the DNCS to clear stored purchases.
4 Format the hard drive in the DHCT if the DHCT is a Home Entertainment Server
with a DVR. For further instructions, see Format the Hard Drive Without
Clearing NVM (on page 157).
Detailed instructions for these procedures are included in this section.
Placing the DHCT into Service Disconnect Mode
This process assumes that your system is using Service Disconnect Mode. If not, then
the DNCS system operator must use one of the following to remove the menu
settings for the DHCT:
A billing transaction that sends a reset client NVM transaction–Refer to your

billing system documentation for instructions and specific information.
The DNCS Addressable Config option–Refer to Enhancing Your Subscribers'

Experience: SARA Configurable Options (part number 4002178) or your DNCS
Online Help for more information.
Complete the following instructions to prepare the DHCT for clearing NVM and
checking for stranded PPV events.
1 Connect the DHCT in a two-way staging area. Wait until the LED displays the
time or before proceeding.
Important: A DHCT will attempt to upgrade its software when you connect the
RF cable and turn on the power. If this occurs, let the upgrade complete and wait
until the LED displays the time or [- - - -] before continuing this procedure.
Note: For POWER LED only DHCTs, the POWER LED either blinks four times,
pauses, then repeats only once (for normal operation); or the LED blinks eight
times, pauses, and repeats (for Service Disconnect Mode [- - - -]).
2 Send a hit to the DHCT from your billing system to place the DHCT into Service
Disconnect mode.
