terminal/PC on one end and RJ-45
for device console port connectivity
on the other.
Converts DB-9 of AL2011013-E6
console cable to RJ-45, a Category 5
RJ-45 straight cable can then
connect to RJ-45 console port.
Converts DB-9 MALE to RJ-45 serial
port. The adaptor can be used for PC
or device with DB-9 MALE console
port. Also, can be used with Category 5
RJ-45 straight cable to provide
console connection.

Prepare the rack
1. Provide the equivalent of one rack of vertical space for each switch in an EIA or
IEC-standard 19-inch (48.2-centimeter) equipment rack.
2. Ensure that the equipment rack is stable and securely attached to a
permanent structure.
3. 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. AVAYA recommends using a
filter or surge suppressor.

Front-mount the switch in a rack
1. Attach the brackets to each side of the device using the screws provided.
2. Slide the switch into the rack. Insert and tighten the rack-mount screws.
To rear-mount the switch in a rack, see Installing the Avaya Ethernet Routing Switch

Stacking
The Avaya ERS 4900 Series provides fail-safe stackability. You can connect up to eight 4900
Series devices in a stack to provide uninterrupted connectivity for up to 400 ports. The stack is
managed as single unit, using the IP address of the base unit.
ERS4900 series rear panel
The switch back panel provides a Base Unit Select switch, Cascade Down connector, and
Cascade Up connector for stacking purposes as shown below:
Cascade Cascade Ports
Up Down
Base Unit Select switch – used to designate the base unit in a stack. When set DOWN, this unit
acts as the Base Unit for the stack. Only one switch in the stack must have the Base Unit Select
in base position.
Ports – used for device management and cannot be used to access network (out-of-band
management). For more information, see Quick Start Configuration for Avaya Ethernet
Routing Switch 4900 and 5900 Series (NN47211-500)
Note: The port labeled AUX is disabled.
Cascade Down and Cascade Up connectors – used 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
connector of the next switch in the stack (shown in the simple two-switch stack connection block
diagram below):

1= Base unit
2= Last unit
3= Cascade/Stack Cable
To create a stack connection, order the appropriate Avaya ERS 4900 Series cascade cables to
ensure fail-safe stacking. For stacking three or more units (maximum eight units per stack),
order the cables as applicable (see other optional requirements).
1. Ensure that all switches for the stack are rack mounted.
2. Slide the Base 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 Base Unit Select switch DOWN
• Non-Base Unit (Units 2-8) - Slide the Base Unit Select switch UP.
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: Avaya recommends you to use a Cascade Down configuration.
