Stand-Alone and Stacked Configurations
Stand-Alone
A stand-alone OmniSwitch 6850 Series switch is ideal for
small and medium-sized network edge applications, offering
24 ports (OS6850-24, OS6850-24X, OS6850-P24,
OS6850-P24X, OS6850-24L, OS6850-P24L, OS6850-U24X)
and 48 ports (OS6850-48, OS6850-48X, OS6850-P48,
OS6850-P48X, OS6850-48L, OS6850-P48L) switches.
These switches provide support for enterprise-based devices,
such as computer workstations or IP telephones.
A single OmniSwitch 6850 Series switch also supports 10Gigabit Ethernet uplinks for high-bandwidth connections to a
backbone or server.
the stack. This provides a virtual chassis with a 10/100/1000
capacity of up to 384 ports.
Note. Switches should be added one at a time in a stack.
Stacked Configurations
In addition to working as individual, stand-alone switches,
OmniSwitch 6850 Series switches can also be linked together
to form a single, high-density virtual chassis known as a stack.
Note. You cannot mix OS6800 and OS6850 switches in a
stack.
Stacking switches provides scalability by allowing users to
quickly and easily expand 10/100/1000 port density. Twentyfour 10/100/1000 ports are added for each OS6850-24,
OS6850-24X, OS6850-P24, OS6850-P24X, and
OS6850-U24X switch brought into the stack; forty-eight
10/100/1000 ports are added for each OS6850-48,
OS6850-48X, OS6850-P48, OS6850-P48X, and switch.
Twenty-four 10/100 ports are added for each OS6850-24L and
OS6850-P24L switch brought into the stack; forty-eight
10/100 ports are added for each OS6850-48L and
OS6850-P48L switch.
Up to eight switches can be stacked. OmniSwitch 6850 Series
switches can be mixed and matched in any combination within
As with the stand-alone configuration, a stacked virtual chassis configuration provides Gigabit Ethernet uplinks and 10Gigabit Ethernet uplinks to a backbone or server.
Network Applications

Availability Features
Chassis Types
The switch provides a broad variety of availability features.
Availability features are hardware- and software-based safeguards that help to prevent the loss of data flow in the unlikely
event of a subsystem failure. In addition, some availability
features allow users to maintain or replace hardware components without powering off the switch or interrupting switch
operations. Combined, these features provide added resiliency
and help to ensure that the switch or virtual chassis is consistently available for day-to-day network operations.
Some key availability features include:
• Management Module Redundancy
• Software Rollback
• Backup Power Supplies
• Hot Swapping
• Hardware Monitoring
For information on these availability features, refer to the
OmniSwitch 6850 Series Hardware Users Guide.

Power Supplies
OmniSwitch 6850 Series switches support power supply
components. The components include:
• PS-120W-DC backup power supply module
• PS-126W-AC backup power supply module
• PS-360W-AC backup power supply module
• PS-510W-AC backup power supply module
• Backup power supply connector cable
When backup power supply components are installed, the
primary (factory-installed) power supply continues to take on
the full power load for switch operations. Meanwhile, the
backup power supply operates in active standby mode. If the
primary power supply fails unexpectedly, the backup power
supply automatically takes up the full power load without
disrupting the switch.
.
The OmniSwitch 6850 Series backup power supply system is
chassis-based with each chassis supporting up to eight backup
power supplies. This provides 1:1 redundancy for stacks of up
to eight switches

Recommendations
• Unpack your OmniSwitch chassis as close as possible
to the location where it will be installed.
4 Carefully remove any foam pads and protective plastic
from the switch chassis.
Note. Alcatel provides factory-installed blank cover plates
for empty backup power supply or 10-Gigabit expansion
module bays. Do not remove these cover plates unless a
backup power supply or expansion module is to be
installed immediately at the corresponding bay.
5 If you are installing multiple switches in a stacked
configuration, repeat steps 1 through 4 for the remaining
switches that will make up the stack.
• Depending on your order, Small Form-Factor Plugga-
bles (SFPs), stacking cables and backup power supply
components may be packaged separately. In order to

Setting Up the Switch
Never obstruct the air vents located at the left and right sides
of the chassis.
Note. Due to their airflow and access requirements,
OmniSwitch 6850 Series switches cannot be wallmounted.
Airflow Considerations
Be sure that your switch is placed in a well-ventilated, staticfree environment. Always allow adequate clearance at the
front, rear, and sides of the switch.
The following diagram shows recommended minimum clearances for adequate chassis airflow and access to components at
the rear of the chassis.
Rear. 5 inches minimum
at rear of chassis.
Sides. 2 inches minimum
at left and right sides for
chassis airflow.
Note. Clearance is not required at the top and bottom of
the chassis. For detailed chassis airflow diagrams, refer to
the OmniSwitch 6850 Series Hardware Users Guide.
Installation Options
There are two ways in which the OmniSwitch 6850 Series
switches can be installed:
• Tabletop installation
• Rack-mount installation

Installing the Switch on a Tabletop or Bench
OmniSwitch 6850 Series switches can be installed freestanding as tabletop units. Place your switch on a stable, flat, and
static-free surface.
Note. OmniSwitch 6850 Series switches must be placed
“right side up.” Never attempt to operate a switch positioned on its side.
Tabletop Mounting Steps
To install the switch as a tabletop unit, follow the steps below:
1 Position the chassis on the table or bench where it is to
be installed.
2 Be sure that adequate clearance has been provided for
chassis airflow and access to the front, back, and sides of
the switch. For recommended clearances, refer to page 16.
Also, be sure that you have placed the chassis within reach
of all required AC power sources.
Note. If you are installing a single (i.e., stand-alone)
switch, continue to “Connections and Cabling” on page 24
for additional setup procedures.
If you are placing multiple switches in a stacked configuration, carefully stack the remaining switches, one on top
of the other. Up to eight switches may be stacked to form
a single virtual chassis. Be sure to maintain adequate
clearance at the front, rear, left, and right side of all
switches (see page 16). Also, be sure that you have placed
all switches in the stack within reach of required AC
power sources.
October 2006 Setting Up the Hardware 17
Rack-Mounting the Switch
Refer to the important guidelines below before installing the
OmniSwitch chassis in a rack.
• Review page 16 for important chassis airflow and
access recommendations before installing.
Rack Mounting Steps
• It is recommended that two people install the switch in
the rack—one person to hold the chassis and position it
in the rack, and a second person to secure the chassis to
the rack using attachment screws (not supplied).
• Alcatel provides two rack-mount flanges with each
OmniSwitch 6850 Series switch. These flanges support
standard 19-inch rack mount installations. These
flanges must be attached to the chassis before the
switch can be rack mounted.
Note. If you are installing the switch in a 23-inch wide
rack, Alcatel offers optional 23-inch rack-mounting hardware. For more information, contact your Alcatel representative.
• Alcatel does not provide rack-mount screws. Use the
screws supplied by the rack vendor.
• To prevent a rack from becoming top heavy, it is
recommended that you install heavier equipment at the
bottom of the rack whenever possible.
To rack-mount the switch, follow the steps below.
Note. Rack-mount flanges may come factory-installed in
some cases. If this is the case, skip steps 1 and 2 below.
1 Align the holes in the provided rack-mount flanges
with the four threaded holes in the OmniSwitch chassis.
These threaded holes are located in the left and right sides
of the chassis, near the front panel.
2 Attach the flanges to the chassis using the provided
Phillips-head screws. Be sure to tighten each of the screws
firmly using a Phillips screwdriver.
