Printed circuit packs (PCPs)
Introduction
The Meridian Mail Modular Option EC uses the following
PCPs:
• Enhanced MMP40 card
• utility card
• voice processor cards (VP4 and VP8)
PCPs ship in their modules. The following sections help you to
replace PCPs that you have removed for any reason, and give
you a complete reference of PCP locations.
CAUTION
Risk of equipment damage
Only the voice processor cards are hot-
pluggable. That is, you can remove or insert
voice processor cards while power to the
module is still on. However, you must use
the “System Status and Maintenance”
function on the administration terminal to
disable the cards prior to removal. See the
System Administration Guide
(NTP 555-7001-301) for details on how to
disable cards.
