1.

 

Confirm that you have the tools and package 

contents as follows:

    Tools Required:

    Phillips #2 screwdriver

    Package Contents:

 

a. 

Ethernet Routing Switch 2500 Series switch

b.

 

Rack and wall mounting hardware

 

• Rack and wall mounting brackets (2)   

 

• Screws for attaching brackets to the  

 

   switch (8)

 

• Screws for attaching the switch to the  

 

  equipment rack (2x4)

 

 

c. 

Adhesive foot pads (4)

d. 

AC power cord

a. 

Provide 2.8 inches of vertical space for each 

switch in an EIA or IEC-standard 19-inch 

(48.2-centimeter) equipment rack.

b. 

Bolt the rack to the floor and brace it, if necessary.

c. 

Ground the rack to the same grounding electrode 

used by the power service in the area. The ground 

path must be permanent and must not exceed 

1 Ohm of resistance from the rack to the grounding 

electrode. Nortel recommends using a filter or surge 

suppressor.

• Category 3, 4, or 5 UTP cable with an RJ-45 connector (for 

100 Mb/s operation)

• Category 5 UTP cable with an RJ-45 connector (for 100 

Mb/s operation)

• Category 5 Four-Pair UTP cable with an RJ-45 connector 

(for 1000 BASE-T ports with 1000 Mb/s operation) 

• Console Port Straight-through serial cable with DB-9 female 

connector at one end

If you are mounting the switch on 

a table or shelf, attach the rubber 

feet to the device as indicated.

Set the device on a flat surface near an 

AC power source, making sure there are at 

least 2 inches (5.1 cm) of space on all sides 

for proper air flow and at least 

5 inches (12.7 cm) at the back for power cord 

clearance.

If you are mounting the switch 

on a rack, attach the brackets to each 

side of the device using the screws

If you are mounting the switch on a wall, position the brackets 

so that the brackets are 90 degrees to the switch side and two-hole

edge faces the bottom of the switch. 

7. 

Connect the AC power cord to the back of the 

switch, and then connect the cord to an AC power 

outlet. 

Warning: You must use a line cord set approved for the 

2500 Series switch and the receptacle type in your country.

8. 

Check the front-panel LEDs as the device 

powers on to be sure the PWR LED is lit. If not, 

check that the power cable is correctly plugged in.

The 2500 Series switches begin switching data as soon as you 

attach network devices and connect the switch to the power 

supply. 

You are now ready to use the 2500 Series switch 

in your network installation.

 To set IP parameters using the console port and CLI Quickstart, 

perform the following tasks:

. Connect a terminal to the console port of the switch.

Any terminal or PC with an appropriate terminal emulator can be 
used as the management station. 

Terminal emulation settings 

lists the parameters that must be used with any terminal emulation 
software used to connect to the switch.

To connect the terminal to the switch console port, you require a 
console cable and connector to match the male DTE connector 
(DB-9) on the switch.

. Set the terminal protocol on the terminal or 

terminal emulation program to VT100 and 
VT100/ANSI.

. Connect to the switch using the terminal or 

terminal emulation application.

. The Nortel switch banner appears when you

connect the switch through the Console port. Enter 
Ctrl+Y and type the following CLI commands:

Welcome to the 2500T setup utility. You
will be requested for information to initially
