INTRODUCTION
1-2 Edition One XC1000 Service
This manual supports XC1000s using software through Release 1.5.
XC1000 can be integrated with up to 16 switches and can support up to
seven system manager/service terminals. Each XC1000 can provide up to
30,000 mailboxes. (XC1000s with software releases earlier than Release 1.2
provide 15,000 mailboxes.)
1.2.1 Hardware
The major components of XC1000 are the logic cards, disk drives, power
supplies, and system-interconnection hardware. The logic cards include the
central processing unit (CPU), a monitor card, system and message file
cards, telephone interface cards (TICs), either digital line cards (DLCs) or
fax-capable universal DLCs (UDLCs), and an optional asynchronous
communications processor (ACP) card. These components are described in
Chapters Ten and Twelve.
XC1000 is available in three configurations:
-
The
Single Cabinet, Nonredundant
configuration includes one CPU,
one system file card, one message file card, and one optional ACP card,
as shown in cabinet 1 of Figure 1-1. The cabinet contains six TIC slots
and six DLC slots, allowing up to three line-card groups (composed of
TICs and DLCs), for a total of 72* ports, and a +5-Vdc and +12-Vdc
power supply. The XC1000 can also contain a5-Vdc and +12-Vdc
power supply to configure the system with redundant power-supply pairs.
If one power supply fails, the second can provide the full load.
-
The
Dual Cabinet, Nonredundant
configuration includes one CPU,
one system file card, one message file card, and one optional ACP card
(Figure 1-1, cabinets 1 and 2). The two cabinets together have 12 TIC
slots and 12 DLC slots, allowing up to six line-card groups (composed
of TICs and DLCs), for a total of 144* ports, and two redundant
+5-Vdc and two red12-Vdc power-supply pairs. If one power
supply fails, the second in the pair can provide the full load.
-
The Dual Cabinet, Redundant configuration includes two CPUs, two
system file cards, two message file cards, and one optional ACP card.
One card of each pair, designated
A , runs the system. If the A card
fails, the B card assumes control following an automatic system
reboot. The two cabinets together have 12 TIC slots and 12 DLC slots,
allowing up to six line-card groups (composed of TICs and DLCs), for a
total of 144* ports, and two red5-Vdc and two redundant
+12-Vdc power-supply pairs. If one power supply fails, the second in
the pair can provide the full load.
Figure 1-2 shows the interaction among XC1000 logic cards and drives.
Each logic card has card-status LEDs on the front edge of the card; other
LEDs on the front edge have varying functions, depending on the type of
card. XC1000’s power includes –48-Vdc input-power terminals and the
+12- and +5-Vdc power supplies. Six cooling fans per cabinet help to
maintain a constant temperature within each cabinet.
* The European digital version supplies a maximum of 120 ports, 90 ports in cabinet 1 and 30
ports in cabinet 2.
