Psiber Data Systems Pinger Plus Network IP Tester - Manual (Page 3)

OPERATION
To test a hub, switch, router or NIC connect a patch cable from the
RJ-45 port on the equipment to the RJ-45 jack on the Pinger Plus.
LINK SCREEN
Turn on the Pinger Plus by pressing the “PWR” button. The unit
scans the RJ-45 connection searching for Link signals. If no Link signals
are found, a “No Link” message is
displayed and a REPEAT function is
provided to rerun the search for a Link
Partner. When proper Link signals are
found, the Pinger Plus displays the
connection as a LAN, NIC or an Auto MDI-X port; the capabilites of the
Link Partner; the speed and duplex the Pinger is using for the connection
and the polarity of the connection (normal or reversed). When the Link is
established, the PING, DHCP and
PortID function keys are displayed.
Disconnecting the Pinger will cause the
unit to immediately restart the search
for Link signals.
Note: If a Link Partner is transmitting NLP or MLT-3 Link signals instead
of a Link Code Word, the duplex mode is unknown (shown as “UN” in
the LINK screen) and the Pinger Plus will always connect at half duplex.
PING tests can still be run even if there is a duplex mode mismatch.
PING SCREEN
Pressing the PING function key in the Link Screen presents the
PING Screen. The Up/Down cursor key is used to select: 1) enter and
PING a new IP address 2) PING one of eight preprogrammed IP
addresses (see IP List Setup) 3) PING
all of the one to eight preprogrammed
IP LIST addresses 4) PING a Range of
IP addresses or 5) PING one of eight
Profiles(see Profile Setup).
When an IP Address, IP List or IP Range is selected, pressing the
PING function key transmits the PING packet and “Wait” is displayed
until a response is received. A summary of the PING responses is
displayed showing the number of
PINGs transmitted and the number of
Good and Bad responses. Pressing the
Up/Down cursor key shows, in
numerical order, the results of each
PING including the Round Trip Time
and if the received data is identical to
the transmitted data (Data:Good) or the
data has been corrupted (Data:Bad).
Pressing the INFO function key
displays the MAC address of the PINGed IP address. If no PING
response is received within specified Timeout time (see Timeout Setup),
“No Response” is displayed. When the PINGed IP address is in a
different subnet than the Pinger IP address, the unit first attempts to locate
the default gateway. If the gateway does not respond, the Pinger
displays a “NOGW” message indicating either the gateway is not
operating properly or an incorrect gateway IP address was entered.
When a PING response is received from another subnet, the MAC
address of the Gateway is shown (GW MAC) by pressing the Info key.
PORT ID SCREEN
Pressing the PortID function key in the Link Screen presents the
Port ID Screen. As soon as this screen appears, the Pinger begins
transmitting a pattern of Link signals
that will cause the hub,switch or NIC
Link LED to blink or stay on continu-
ously. Identifying the specific port a
wall outlet/PC is connected to can aid
in diagnosing the cause of failed PING tests. Hubs and switches from
various manufacturers have different specifications for the time it takes
for Link signals to turn the Link LED on and off. The Pinger Plus has four
different blink rates and a continuous mode that can be selected by
pressing the Up/Down cursor key. An initial test directly at the hub or
switch will determine the best blink rate setting before conducting a
Port ID test at a wall outlet.
SETUP
Pressing the SETUP key in any screen presents the Setup
Screen.The Up/Down cursor key is used to display: 1) Pinger IP
Address Setup 2) Pinger Subnet Mask
Setup 3) Pinger Gateway Setup 4)
Pinger IP List Setup 5) Pinger MAC
Screen 6) Profile Setup 7) Default
Profile 8) Ping Count 9) Packet Size
10)Time Out 11) Power Down Time Setup 12) Password Setup or 13)
Pinger Update . Press the SELECT function key to enter the displayed
setup screen. The Pinger MAC is shown for information only and can
not be changed.
IP LIST SETUP SCREEN
The IP List Setup screen is used to enter from one to eight names and
IP addresses. The Pinger can then PING the entries individually or PING all
entries sequentially.
Data Entry - Use the Up/Down cur-
sor key to select one of the eight storage
locations and press the right arrow key
to display the cursor and begin entering
a new name or editing an existing one.
Use the data entry keypad to input the number or letter (each time the key
is pressed the next letter or number on the key is displayed). Pressing the
right cursor key advances to the next character. Pressing the left cursor
key selects the previous character. Names can be a maximum of ten
characters long. Pressing the right cursor key an eleventh time advances
the cursor to the IP Address which is divided into four fields of three
characters. Only numbers can be input in the fields and the maximum
valid number for any field is 255. Single digits can be entered in any of the
three character locations and will be right hand justified when the cursor is
moved to the next field. Two digit numbers can be entered in the left two or
right two character locations. If an invalid number is entered, the cursor will
not advance to the next field. After entering or editing the name and IP
address, press the SAVE function key to store the information in non-volatile
memory. The information is retained even if the unit is turned off or the
batteries are removed. To remove an entry from the list, press the right
cursor key to select the entry and then press the star key. A “Delete Entry”
message is displayed and pressing the SAVE function key clears the
selected name and IP Address.
