The Ethernet Routing Switch 3500 Series provides fail-safe
stackability. You can connect up to eight ERS 3500 Series devices in a
stack to provide uninterrupted connectivity for up to 192 to 208 ports.
You can manage the stack as a single unit.

To install/add a unit to a stack, you must change the default mode
from standalone to stacking mode and reboot the unit. See Installing
the Ethernet Routing Switch 3500 Series for more details.

Note: Stacking is not available for ERS 3510GT or ERS 3510GT-PWR+
switches. Stacking is only supported with switches operating with
Release 5.1 or later software.

The Ethernet Routing Switch 3524GT, 3524GT-PWR+, 3526T,
3526T-PWR+, 3549 GTS, and 3549 GTS-PWR+ back panel provides a
Unit Select switch, Cascade Down port, and Cascade Up port for
stacking purposes as shown below:

Base Unit Select Switch – used to designate the base unit
in a stack.

Cascade Down and Cascade Up ports – used to connect a switch to
the next unit in the stack through a cascade cable. Connect one end
of the Cascade Down cable to the Cascade Up port of the next switch
in the stack (shown in the three-switch stack connection block
diagram below):

Base Unit Select switches

To create a stack connection, order the appropriate Ethernet Routing
Switch 3500 Series cascade cables to ensure fail-safe stacking. For
stacking three or more units (maximum eight units per stack), order
the 46 cm, 1.5 m, or 3 m cables as applicable (see “Before You Start” –
step 3 for Order Codes).

1. Ensure that all switches for the stack are rack mounted.

2. Slide the Unit Select switches on the back of the units to the

appropriate
position, depending on whether they are a base unit or non-base
unit:

• Base Unit (Unit 1) - Slide the Unit Select switch to the RIGHT

• Non-Base Unit (Units 2-8) - Slide the Unit Select switch to the
LEFT

NOTE: The Base Unit Select switch defaults to be in the Non-Base
position. Only one switch in the stack must have the Base Unit Select
switch set to the Base position.

Because stack parameters are associated with the base unit, the
physical stack order depends on the base unit position and whether
you configure the stack cascade up (stack up) or cascade down (stack
down). This designation depends on the stack cabling arrangement.

IMPORTANT: Extreme Networks recommends that you use a Cascade
Down configuration.

Powering Up

Connect the AC power cord to the back of the switch or switches,
and then plug the other end of the cord into an AC power outlet. If
powering up a stack of switches, power on all switches together.

Check the front-panel LEDs as the device powers on to be sure the
PWR LED is lit. If not, check that the power cord is plugged in correctly.

Warning: You must use a power cord set approved for the ERS 3500
Series switch and the power receptacle type in your country.

The ERS 3500 Series switches begin switching data after the switch
is powered up and has loaded the agent code software which is
indicated by both the PWR and Status LEDs being lit solid green.

To set IP parameters using the console port and CLI Quickstart,
perform the following tasks:

a. 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. The Terminal emulation settings
table below lists the parameters that must be used with any
terminal emulation software used to connect to the switch.

To connect to the switch
console port, you require a
console cable with an RJ-45
connector to match the
console port on the switch.

b. Set the terminal protocol on the terminal or terminal emulation program to

VT100 and VT100/ANSI.

c. Connect to the switch using the terminal or terminal emulation application.
d. The Extreme switch banner appears when you connect to the switch

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

• enable

• install
The ERS 3500 will set a default IP address of 192.168.1.1/24 by default if the

The console port is the RJ-45 port shown with a blue border outline
on the front of your ERS 3500 Series switch (note orientation). The
port is labeled console, and can be used to establish a management
terminal connection to the switch.

You can use an RJ-45 to DB-9 cable to connect the switch console port to
your management terminal. Extreme recommends you use the RJ-45
Console Cable part number: AL2011022-E6. Alternatively a DB-9 to RJ-45
adapter or other suitable console cables can be used - the maximum length
of a console cable is 25 feet (8.3 meters). The following table describes the
RJ-45 console port pin-out information. You can use the pin-out information
to verify or create a console cable for use with your maintenance terminal.
