Precautions
Contents This section contains the following topics:
•“General precautions” (page 17)
•“Circuit cards” (page 17)
General precautions
CS 1000 equipment is based on solid state circuitry that is sensitive to
static electricity and environmental conditions. Follow the precautions in
this chapter to avoid personal injury and equipment damage.
DANGER
To avoid the danger of electric shock, be careful when working
with power equipment and connections. Warning notices are
displayed and must be heeded.
Wear an antistatic wrist strap when handling circuit cards to prevent
damage caused by static electricity.
Circuit cardsHandle the circuit cards as follows:
•Wear an antistatic wrist strap before handling circuit cards.
•Handle the cards by the card stiffeners and edges only. Do not touch
the contacts or components.
•Keep the cards installed in the system as much as possible to avoid
dirty contacts and unnecessary wear.
•Set the cards on a protective antistatic bag. If an antistatic bag is
not available, hold the card, or set it in a card slot unseated from the
connectors.
•Unpack or handle the cards away from electric motors, transformers,
or similar machinery.

.

18 Precautions
•Store the cards in protective packing. Do not stack cards on top of
each other unless they are packaged.
•Store the cards in a dry dust-free area.
During repair and maintenance procedures:
•Turn off the power switch, if there is one.
•Software-disable the cards, if applicable, before they are removed or
inserted.
•Hardware-disable the cards, whenever there is an enable/disable
switch, before they are removed or inserted.
•Insert the cards into compatible slots only.
•Return defective or heavily contaminated cards to a repair center; do
not try to repair or clean them.

Communicating with the system
Contents This section contains the following topics:
•“Introduction” (page 19)
•“System terminal access for CP PIV Call Processors” (page 19)
•“System terminal access for Gateway Controllers” (page 21)
•“Element Manager” (page 22)
•“Accessing the system” (page 22)
IntroductionSend maintenance commands and receive system messages (status and
error messages) by communicating with the system through one or more
of the following input/output devices or management tools:
•TTY or VDT terminal as an input/output device
•PC running terminal emulation software
•RS-232-C compatible printer as an output-only device
•Maintenance telephone as an input-only device
•Element Manager
See Communication Server 1000E Installation and Commissioning
NN43041-310 for information about how to connect these devices and
management tools.
System terminal access for CP PIV Call Processors
Terminal Server
Because each CS 1000E Core Call Server provides only two ports for
serial devices, the Terminal Server is used to provide the necessary
standard serial ports for applications and devices that require them, such
as printers and Call Detail Recording (CDR). The Terminal Server is also
used to connect maintenance terminals and modems for support staff.

.

20 Communicating with the system
The Terminal Server provides an rlogin service that allows serial devices
to establish dedicated connections to pseudo TTY (PTY) ports on the Call
Server. (The Terminal Server therefore serves the same purpose as Serial
Data Interface [SDI] and Multipurpose Serial Data Link [MSDL] cards in
Large Systems.) You can telnet through the Terminal Server to individual
components on the ELAN subnet, and therefore obtain maintenance
access for each device. You can also access the Terminal Server from a
remote PC by dialing the onboard modem.
As the Terminal Server is configured to automatically log in to the active
Call Server upon startup, only one Terminal Server is required for each
Call Server pair.
While the Terminal Server is needed for serial port access to the Call
Server, it can also be optionally configured to provide access to Media
Gateway 1000T (MG 1000T) serial ports for maintenance purposes.
For more details on installing and configuring the Terminal Server, see
Communication Server 1000E Installation and Commissioning .
System terminal
When a system terminal is installed locally, it is typically connected to
a serial port on the Terminal Server. This ensures continued access to
the active Call Server. When a system terminal is installed at a remote
location, a modem and a telephone line are required between the system
terminal and the Terminal Server.
Figure 1 "CS1000E local and remote access system terminals" (page
20) shows a typical system terminal configuration to the Call Servers.
