Troubleshooting IP on an SV8100 System
SECTION 1 INTRODUCTION
This book provides some helpful tips for troubleshooting IP on the
UNIVERGE® SV8100 system.
SECTION 2 PING
This is one of the most useful tools available to troubleshoot IP
connectivity. PING is a standard component of Microsoft Windows®and is
also implemented on the UNIVERGE SV8100 IP Phones. Ping sends a
small IP packet to a specified destination and waits for a response back.
It should be possible to ping IP Phones, the CD-CP00-US (CPU),
PZ-32IPLA (32 VoIP), PZ-64IPLA (64 VoIP), PZ-128IPLA (128 VoIP) and
any other devices on the network. Send a ping and wait for a reply. If a
reply is not received, the ping response “times out”. This indicates a
connection problem.
Refer to Figure 1-1 Ping Traces on page 1-2 for examples of these two
conditions.

System Maintenance Manual 1 - 3
If unable to ping a device, it may mean that either the source or destination device:
Ris not configured correctly
Ris not connected to the LAN (e.g., cable disconnected)
Rhas a developed a fault
Ror any device in between the source or destination may be faulty (e.g., routers)
2.1 Pinging from a PC
The command syntax for ping is:
ping [-t] [-n count] [-l size] target
-t (optional) continually sends PING requests until Ctrl-C is
pressed to cancel -n (optional) sends a specified number of PING
requests -l (optional) sends packets of a specified size (bytes)
target the destination IP address or host name
Note that there are other options available with the Microsoft Windows®
implementation of ping. The most commonly used options are listed above.
Examples:
Pping 192.168.2.100 -t Continually pings 192.168.2.100 until Ctrl-C
pressed
P192.168.2.100 -n 10 -l 40 Sends ten 40-byte packets to 192.168.2.100
Pping 192.168.2.100 Sends four 32-byte packets (default) to
192.168.2.100
2.2 Pinging from an UNIVERGE SV8100 IP Phone
The System IP Phone has a version of ping within the Maintenance Menu.
Hold down help button for 3 sec
Press 3 (Ping)
Enter address
Press OK
The following options are available:
1. Echo request start: Starts the ping process using the settings in options
2 and 3 below.
2. Destination address: The target destination IP Address
3. A successful ping results in: 1.OK 2.OK 3.OK 4.OK Complete
A unsuccessful ping results in: 1.NG 2.NG 3.NG 4.NG Complete

Issue 1.0 UNIVERGE SV8100
1 - 4 Troubleshooting IP on an SV8100 System
An example of ping usage:
A UNIVERGE SV8100 IP Phone unsuccessfully attempts to connect to the
UNIVERGE SV8100 system as shown in Figure 1-2 Ping Usage Example.
As seen in Figure 1-2 Ping Usage Example, there are several devices that
could cause a connection problem:
PUNIVERGE SV8100 IP Phone [phone])
PLocal Hub
PLocal Router (192.168.1.1)
PLeased Line
PRemote Router (192.168.2.1)
PRemote Hub
PUNIVERGE SV8100
You will see that by pinging from the System IP Phone and PCs, we can work
out where the problem lies by process of elimination. We start by pinging the
nearest device and working outward toward the intended destination.

Examples:
PThe UNIVERGE SV8100 IP Phone can successfully ping all devices up to
and including the local router. Anything beyond that point fails. This would
suggest that the Leased Line or remote router has a problem.
PThe local PC (192.l68.1.101) can ping all devices except the UNIVERGE
SV8100 IP Phone. The UNIVERGE SV8100 IP Phone can not ping
anywhere. This would suggest that there is a problem with the UNIVERGE
SV8100 IP Phone or its connection to the switch/hub.
SECTION 3 PACKET TRACES
It is possible to use a packet trace utility (also known as “Sniffers”) to determine what
data is being transmitted and received on an ethernet network. These can be
particularly useful to determine the cause of connection issues or voice quality issues.
The packet trace utility has to be run on a PC that is connected to the same hub (not
a switched hub) where the UNIVERGE SV8100 system or UNIVERGE SV8100 IP
Phone is connected.
There are many utilities available that will allow packet trace to be run on a network.
One such utility is Ethereal. This is a software application distributed under a GNU
general public license (www.wireshark.org). This allows the files to be captured and
saved in a standard format for analysis later.
A sample trace file is shown in Figure 1-3 Trace File Example on page 1-6.

System Maintenance
SECTION 1 INTRODUCTION
The technician can use this book to troubleshoot and diagnose problems
during and after system installation. The troubleshooting flow charts and
general test procedures help the technician identify possible causes of the
problem by defining the problem area.
Using the System Data Upload/Download feature, all System
Programming and Speed Dial data can be stored on disk for safe keeping.
After all System Programming is completed, it should be downloaded to a
disk for backup. When system memory fails, this data on the disk can be
uploaded and the memory restored.
SECTION 2 OPERATIONAL TEST PROCEDURES
2.1 General Information
When an UNIVERGE SV8100 system is first powered up, an
initialization is performed. During this process the CD-CP00-US
(CPU), located in the first chassis, scans each interface slot to
determine the hardware configuration used. This information is
stored in the resident system program memory with the system
default values. This section provides test procedures that are used
before, during, and after the initialization process.
2.2 Before Initializing
The technician must follow these steps before initializing the
system.
2.2.1 Cable Connections
All wiring for power supplies or flat cable connectors
should be checked for solid connections.

Issue 1.0 UNIVERGE SV8100
2 - 2 System Maintenance
2.2.2 Initialization Check
To determine if the system is initializing correctly, only the first
chassis, CD-CP00-US, one CD-8DLCA, and terminals should be
installed on the system. After initialization, all the terminals assigned
to the CD-8DLCA can be used for internal calls to one another. (By
default, these stations are assigned station numbers 101~108).
2.3 System Initialization
Before initialization is performed and verified, the entire system should be
initialized.
With power OFF, all interface and option cards can be installed in the
controlling chassis. The technician can then power up the system to perform
a First Initialization. After the initialization, each station display shows default
time and date indications.
For example: 12-2 Fri 10:47 AM
2.4 After Initialization
Check all blade slots in software to ensure the initialization process scanned
the installed hardware correctly.
A general system operation check should be performed using default values
prior to system programming.
After all previous steps are performed and any problems corrected, system
programming is complete.
After System Programming is finished, the technician should perform a
Second Initialization. Performing the First Initialization a second time causes
all programming memory to be lost. Second Initialization refreshes the system
RAM without losing any memory.
This completes the installation procedure for the UNIVERGE SV8100 system.
The technician should check the operation of each Multiline Terminal to
ensure the system is working properly.
Ensure that the battery is installed in CN15 on the
CD-CP00-US.
