Server 1000M and Meridian 1 Small System Planning and Engineering
(NN43011-220). This section contains worksheets to help you determine
the power draw for the UPS.
Circuit cards
The Chassis system supports the NTDK20 SSC card and the NTDK16
48-port Digital Line Card. This section provides a short overview of these
two cards. For more information about other circuit cards supported on the
Chassis system, refer to
"Installing optional circuit cards" (page 193) .
NTDK20 SSC card and components
The NTDK20 SSC card includes:
• a Central Processing Unit (CPU) that handles call processing
• an Ethernet controller
• system memory
New systems are shipped with the NTDK20 SSC card, with 32 MB DRAM.
You must install the SSC card in slot 0.
Software Daughterboard
The NTDK20 SSC card requires a software daughterboard in order to
function. The NTTK25 Software daughterboard provides 64 MB of storage
for system and customer data. It can be ordered preprogrammed with
system software and customer data.
For CS 1000 Release 4.5 software, the minimum requirements are:
• 32 MB DRAM
• 16 MB primary flash
• 32 MB program store
An NTDK20 SSC card with 32 MB DRAM and equipped with an NTTK13 or
NTTK25 Software daughterboard meets the minimum requirements.
PC Card interface The NTDK20 SSC card has a 2-slot PC Card interface
socket located on its faceplate (socket A is used for installations and
upgrades, socket B is used for backups). You can insert a Software Delivery
card (PC Card) into the socket. Use the PC Card for software upgrades on
an existing Chassis system. You can also use this socket for creating an
external backup copy of the customer database.
SDI ports The NTDK20 SSC card contains three SDI ports used to
connect on-site terminals or remote terminals through a modem.
