Lifting system equipment
Care should be exercised when lifting system components. If necessary, get
assistance to lift a component or install a component in a rack. The weight of
the system component can be found in the component profiles in “System
components” on page 41.
Before lifting or installing a component:
•Ensure that the planned location and the route to that location are free of
obstacles and debris.
•Determine the weight of the components (see component profiles in
“System components” on page 41).
•Get help with heavy components or components that are to be placed in
the upper section of a rack.
Handling circuit cards
CAUTION WITH ESDS DEVICES
Static electricity can damage circuit cards. Wear an
antistatic wrist strap when handling circuit cards or their
components.
Follow these precautions when handling circuit cards:
1Unpack or handle cards away from electric motors, transformers, or
similar machinery.
2Handle cards by the edges only. Do not touch the contacts or
components.
3Set cards on a protective antistatic bag. If an antistatic bag is not
available, hold the card or set it in a card slot unseated.
4Store cards in protective packing.
5Do not stack cards on top of each other unless they are packaged.
6Wear a properly connected antistatic wrist strap when you work on the

Installing telephones
Follow these safety instructions when installing telephone equipment:
•Never install telephone wiring during a lightning storm.
•Never install a telephone jack in wet locations unless the jack is designed
for wet locations.
•Never touch an uninsulated telephone wire or terminal unless the
telephone line is disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Using telephones
These safety precautions are intended to reduce the risk of fire, electric shock,
and personal injury. Always follow these basic safety precautions when using
telephone equipment:
•Follow all warnings and instructions marked on the product.
•Before you clean a telephone, removethe plug from the wall outlet. Use
a damp cloth for cleaning. Do not use liquid cleaners or aerosol cleaners.
•Do not use the telephone near water (for example, near a tub or sink).
Safety instructions Page 35 of 488
•Do not place the telephone on a piece of furniture that is unstable. The
telephone can fall, causing serious damage to the telephone.
•Slots in the Media Gateway and the telephone are for ventilation. These
slots protect the equipment from overheating. Never block or cover these
slots.
•Never block the openings on a telephone by placing it on a surface like a
bed, sofa, or rug. Never place a telephone near or over a radiator or heat
register. Do not place it in a built-in installation, unless there is correct
ventilation.

your distributor.
Communication Server 1000EInstallation and Configuration
Page 36 of 488 Safety instructions
•Some equipment has a three-wire grounding plug. This type of plug has
a third grounding pin. As a safety feature, the plug only fits into an
isolated ground outlet. If you cannot insert the plug completely into the
outlet, contact your electrician to replace the outlet.
•Some equipment has a polarized line plug. This type of plug has one
blade wider than the other. As a safety feature, this plug fits into the
power outlet one way. If you cannot insert the plug completely into the
outlet, try reversing the plug. If the plug still does not fit, contact your
electrician to replace the outlet.
•Do not place objects on the power cord. Do not locate the product where
persons can walk on the plug.
•Do not overload wall outlets and extension cords, as fire or electrical
shock can result.
•Never push objects of any kind into the telephone through the slots. The
objects can come in contact with dangerous voltage points. Also, parts
can short out, causing the risk of fire or electrical shock.
•Never spill liquid of any kind on the product.
•To reduce the risk of electrical shock, do not disassemble a telephone
product.
•Removethe telephone plug from the wall outlet and refer servicing to
qualified personnel if:
— the power supply cord or plug is damaged or worn
— liquid has spilled into the telephone
— the telephone has been exposed to rain or water
— the telephone has been dropped or damaged
— the product shows a distinct change in performance
— the telephone does not function correctly under normal
operating conditions
•Avoid using a telephone (except a type without a cord) during an
electrical storm. There is a remote risk of electric shock from lightning.
•Do not use the telephone to report a gas leak in the area of the leak.

Backup and restore enhancements
The backup rules group of commands was introduced in CS 1000 Release 4.0
with the single rule type Secondary Call Server (SCS). Backup and restore
553-3041-210Standard 4.00September 2007
enhancements apply to both CP PII and CP PIV system configurations, unless
otherwise noted.
Note: This feature does not actually perform an EDD, which must be
initiated through an appropriate command in LD 43.
New backup rules
Three new backup rule types are introduced with CP PIV:
•FTP — an external FTP server is accessed for storing or retrieving
backup data.
•FMD — fixed media device for storing backup data in a special directory
on the /u partition. A CP PII system stores the data on a local hard drive,
while a CP PIV system uses an on-board Compact Flash card.
•RMD — removable media device for storing backup data. The RMD rule
type is available only on a CP PIV system.
Note: New backup rules are not available for Geographic Redundancy
Database Replication Control (GRDRC).

The BayStack 460 Layer 2 switch, shown in Figure 12 on page 63, adds
power in addition to data communications over standard Category 5 LAN
drops for powering the IP Phones. The LAN power system eliminates the
need to connect each telephone to an AC power outlet saving in desktop
wiring and also allowing centralized UPSs for power backups. Using a Power
over LAN unit eliminates the need to use separate power transformers for
each IP Phone.

MRV Terminal Server
The Terminal Server, described in Table 8 on page 65, provides the dedicated
rlogin service used to establish serial connection between a CS 1000E and
various serial devices. The IP-based Terminal Server provides standard serial
ports for applications that use a serial port interface. These applications
include billing systems that analyze Call Detail Recording (CDR) records,
Site Event Buffers (SEB) that track fault conditions, and various legacy
applications such as Property Management System (PMS) interface and
intercept Computer applications. In addition, serial ports are used to connect
maintenance terminals and modems for support staff.
Communication Server 1000EInstallation and Configuration
Page 64 of 488 System components
Note: PTY ports are software ports and will not work until the system
has completed its INI or SYSLOAD . These ports cannot be used by a
SEB to track INI/SYSLOAD faults as they will not be able to see these
issues. If you wish to capture these messages using an SEB, it is
recommended that it be connected to a TTY port such as Port 0, which
displays SYS/INI messages.
The Terminal Server is configured to automatically log in to the active Core
Call Server upon start-up. It always connects to the Active CPU IP address.
The CS 1000E can configure up to 16 serial ports for applications within the
configuration Data Block. Ports can be configured by using:
•login userid of "PTYnn" – TTY ports are specified where nn is the PTY
port number configured for a particular TTY within LD 17. If a "PTYnn"
userid is specified and that port is busy because of another login, an error
message will be produced (on the maintenance consoles, in the report
log, or as SNMP alarms).
•no userid or the OTM userid – the highest available PTY port number is
selected
The Terminal Server has the following attributes:
•support “rlogin” protocol on local access mode
•support transparent, or binary mode, on “rlogin” connection
•support port speed up to 115kbps
•support auto rlogin connection and auto-retry after being disconnected
•support BOOTP
•support DHCP

Introduction
All CS 1000E system components are installed in a customer-supplied,
19-inch rack. Also refer to the equipment layout plan and card slot assignment
plan for additional information.
Component air circulation is either from front to back or from side to side.
Therefore, components can be mounted immediately above or below an
installed component. The rack’s u pattern provides adequate clearance
between components. For example, a Media Gateway Expander could be
installed in the next 5u pattern of mounting holes below an already installed
Communication Server 1000EInstallation and Configuration
Page 74 of 488 Rack-mounting the components
Media Gateway. The Media Gateway Expander would be approximately
1/4 in from the Media Gateway.
Note: In the 5u pattern, a “u” is equal to 1.75 in. and includes three holes
spaced at 5/8 in. + 5/8 in. + 1/2 in.
Other data communications equipment can be installed in a rack with
CS 1000E system components.
Ensure that the unit’s power cord is appropriate for the area’s electrical
service. Do not modify or use the supplied AC power cord if it is not the
correct type.

Guidelines for component placement in a rack
When installing equipment, the Layer two switches should be in a central
location to allow for easy access of all LAN cabling. The Media Gateways
and Media Gateway Expanders must be mounted together vertically, and they
must be powered from the same power rail. Typical vertical power bars in
equipment racks are rated at 15/20 amps @ 120 volts. Ensure that the
equipment load does not exceed the power bar rating. Refer to
Communication Server 1000E: Planning and Engineering (553-3041-120)
for information on power consumption. Do not place redundant equipment on
the same electrical circuit.

Read the following warnings carefully before you begin installing the Signaling
Server in the rack.
DANGER OF ELECTRIC SHOCK
DISCONNECT AC POWER
The Signaling Server must be completely disconnected
from any AC power source before performing this
procedure. Pressing the Power button DOES NOT turn
off power to this Signaling Server. Some circuitry in the
unit can continue to operate even though the front panel
Power button is off.
Failure to disconnect the Signaling Server from its AC
power source can result in personal injury or equipment
damage.
DANGER OF ELECTRIC SHOCK
GROUNDING THE RACK INSTALLATION
To avoid the potential for an electrical shock hazard,
include a third wire safety grounding conductor with the
rack installation.
If Signaling Server power cords are plugged into AC
outlets that are part of the rack, then provide proper
grounding for the rack itself.
If Signaling Server power cords are plugged into wall AC
outlets, the safety grounding conductor in each power
cord provides proper grounding for the Signaling Server
only. Provide additional, proper grounding for the rack
and other devices installed in it.
Communication Server 1000EInstallation and Configuration

Grounding other rack-mounted components
To ground multiple pieces of equipment in a rack, use a separate ground
connection from each piece of equipment to the ground bar. If a piece of data
communications equipment in a rack does not have a grounding lug then
ground the rack to the ground bar.
When the rack is grounded to the ground bar, the equipment is grounded
using the Single Point Grounding method, as shown in Figure 28 on
page 100.
