Availability ensures that your switch is consistently opera-
tional for your day-to-day networking needs. This added reli-
ability is provided through redundant components for critical
hardware and software subsystems. OmniSwitch 8800
switches provide a broad variety of availability features,
including:
•Software Redundancy
•Hardware Redundancy
•Configuration Redundancy
•Link Redundancy
•Smart Continuous Switching
•NI Module Forwarding During CMM Failover
•Image Rollback
•Hot Swapping
•Hardware Monitoring
•Power Checking Sequence
For more information on Availability features, refer to the
OmniSwitch 8800 Hardware Users Guide, the OmniSwitch
7700/7800/8800 Switch Management Guide, and the
OmniSwitch 7700/7800/8800 Network Configuration Guide.

March 2005 Installing the Hardware 3
Items Required
•Grounding wrist strap (included)
•Phillips screwdriver (not included)
•Flat-blade screwdriver (not included)
•Serial cable (not included)
Site Preparation
Environmental Requirements
OmniSwitch 8800 switches have the following environmental
and airflow requirements:
•The installation site must maintain a temperature
between 0° and 45° Celsius (32° and 122° Fahrenheit)
and not exceed 95 percent maximum humidity
(noncondensing) at any time.
•Be sure to allow adequate room for proper air ventila-
tion at the front, back, and sides of the switch. Refer to
“Mounting the Switch” on page 7 for minimum clear-
ance requirements. No clearance is necessary at the top
or bottom of the chassis.
Electrical Requirements
OmniSwitch 8800 switches have the following general electri-
cal requirements:
•Each switch requires one grounded AC outlet for each
power supply (up to four) installed in the chassis.
OmniSwitch 8800 switches offer both AC and DC
power supply support. Refer to the OmniSwitch 8800
Hardware Users Guide for more information.
•For switches using AC power connections, each
supplied AC power cord is 2 meters (approximately
6.5 feet) long. Do not use extension cords.
Caution. In North America, OmniSwitch 8800 power
supplies require 220 Volt power cords connected to 220
Volt power receptacles. Do not use 110 Volt power cords
or receptacles.
Redundant AC Power. If possible, it is recommended
that each AC outlet resides on a separate circuit. With
redundant AC, if a single circuit fails, the switch’s remain-
ing power supplies (on separate circuits) will likely be
unaffected and can therefore continue operating.

Unpacking and Installing the Switch
Unpacking the Chassis
To protect your switch components from electrostatic
discharge (ESD) and physical damage, read all unpacking
recommendations and instructions carefully before beginning.
Recommendations
•Unpack your OmniSwitch chassis as close as possible
to the location where it will be installed.
•Network Interface (NI) modules and Chassis Manage-
ment Modules (CMMs) are packaged in separate
boxes. In order to greatly reduce exposure to electro-
static discharge (ESD) and physical damage, do not
unpack these boxes until the CMMs and NI modules
are ready to be installed.
Chassis Removal Instructions
1Begin by carefully cutting the tape along the seam
marked “OPEN HERE FIRST.”
2Lift the box’s top flaps. Remove the smaller boxes that
are enclosed and set them aside. These smaller boxes
contain the Ship Kit.
3Next, completely remove the four white plastic inserts
(two on the front and two on the back) from the sides of
the box. Removing these inserts allows the overpack to be
removed.
Caution. Do not attempt to lift the chassis with the white
plastic inserts.
4The overpack is the outer shell of the packaging. Lift
the overpack straight up until it slides free from the rest of
the packaging. This allows easy access to the chassis.
5Remove the two rack-mounting brackets for 19-inch
racks.
Note. See “Rack-Mounting” on page 8 for more informa-
tion on installing the rack-mounting brackets.
6Carefully remove the protective plastic from the switch
chassis.
7In order to reduce the weight of the chassis, it is
recommended that you remove all factory-installed power
supplies prior to lifting it from the packaging.
8Continue to “Power Supply Removal Instructions” on
page 6.
Note. The subsection below applies to power supplies that
are newly-shipped in the switch chassis. They have no
power cords attached and the on/off switches are in the off
( O ) position. For instructions on removing power
supplies that are currently operating in an existing switch,
refer to your OmniSwitch 8800 Hardware Users Guide.

6 Installing the Hardware March 2005
Power Supply Removal Instructions
1Loosen the four captive screws, located at the four
corners of the power supply’s front panel. If necessary,
use a flat-blade screwdriver to loosen the screws. Be sure
that all captive screws are completely disengaged from the
threaded holes in the chassis before continuing.
Note. Alcatel provides factory-installed blank cover plates
for empty module slots. Do not remove these cover plates
as they play an important role in chassis ventilation.
2With one hand, grasp the handle at the front of the
power supply and slowly pull the power supply out of the
power supply bay. Do not pull the power supply
completely out of the bay with one hand.
3When the power supply is pulled out far enough (about
10 inches), place your other hand under the power supply
casing to support its weight.
4Continue pulling the power supply out until it is
removed from the chassis.
5Set the power supply aside on a clean, static-free

March 2005 Installing the Hardware 7
Lifting the Chassis
Once its weight has been reduced by removing the power
supplies, the chassis can be lifted from the packaging material
and moved to the location where it is to be installed (see
important note below).
Important. Two people are required when lifting the
chassis. Due to its weight, lifting the chassis unassisted
can cause personal injury.
Continue to the next section, “Mounting the Switch.”
Mounting the Switch
Note. Due to their weight, access, and airflow require-
ments, OmniSwitch 8800 switches cannot be wall-
mounted.
Airflow Considerations
Be sure that your switch is placed in a well-ventilated, static-
free environment. Always allow adequate clearance at the
front and sides of the switch, as well as behind the switch’s fan
unit (located at the top-rear of the chassis). The following top-
view diagram shows recommended minimum clearances for
adequate airflow.

8 Installing the Hardware March 2005
Never obstruct the air intake vents located at the bottom-front
and bottom-sides of the chassis or the fan unit’s air output
vents located at the rear of the chassis.
Note. Clearance is not required at the top and bottom of
the chassis.
Module Access Considerations
If the switch will be mounted in rack that is immobile, make
sure that you have adequate clearance to install and remove
modules on the front and rear of the chassis. Please allow
enough clearance to install and remove the front fan trays,
which are approximately 15.8 inches long, are the longest
modules on the front. And please allow enough clearance to
remove the Switch Fabric Modules (SFMs) and power
supplies, which are approximately 6 inches long.
Rack-Mounting
Refer to the important guidelines below before installing the
OmniSwitch chassis in a rack.
•Rack-mounting the chassis requires three people—two
people to hold the chassis and position it in the rack
and a third person to secure the chassis to the rack
using the attachment screws.
•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 the switch at the bottom
of the rack whenever possible.
•If you are installing the switch in a relay rack, be sure
to install and secure the rack per the rack manufac-
turer’s specifications.
•Refer to page 7 for important chassis airflow recom-
mendations before installing.
To rack-mount the switch, follow the steps below.
1Using the rack-mounting brackets as a template, mark
the holes on the rack where the chassis is to be installed.
2Attach one rack-mounting bracket to the front end of
the chassis using the Phillips-head screws that came with
the chassis. See the figure below for the positioning and
placement of these brackets and screws.

March 2005 Installing the Hardware 9
3Attach the second bracket to the opposite front side of
the chassis using the remaining screws.
4Using two people, lift and position the chassis until the
rack-mount brackets are flush with the rack post.
5Align the holes in the brackets with the rack holes you
marked in step 1.
6Once the holes are aligned, use a third person to insert
a screw through the bottom hole on each bracket. Tighten
both screws until they are secure.
Note. Be sure to install the screws in the bottom hole of
each bracket, as shown, before proceeding.
7Once the screws at the bottom of each bracket are
secure, install the remaining screws. Be sure that all
screws are securely tightened.

10 Installing the Hardware March 2005
Stand-Alone
The OmniSwitch 8800 can be installed unmounted as a stand-
alone unit. Be sure that the installation location is a stable, flat
surface that can accommodate the fully-populated weight of all
switches being installed. One fully-populated OmniSwitch
8800 weighs approximately 220 lbs (100 Kgs).
Note. OmniSwitch 8800 switches must be installed “right
side up.” Never attempt to operate a switch while it is
lying on its side.
To install the switch as a stand-alone unit, follow the steps
below:
1Use two or more people to move and position the
unpopulated chassis upright on the floor or bench where it
is to be installed.
2Be sure that adequate clearance has been provided for
chassis airflow and that you have placed the chassis within
reach of all required AC outlets. For recommended
airflow allowances, refer to page 7. For environmental and
electrical requirements, refer to page 3.
Installing Power Supplies
Reinstall the power supplies in the chassis power supply bays
by following the steps below.
1Be sure that you do not install the power supply upside
down. When orienting the power supply, note that the on/
off switch and power cord socket are located at the bottom
of the power supply and the fan is located at the top of the
power supply.
2With one hand, grasp the handle at the front of the
power supply. Place your other hand under the power
supply casing to support its weight.
3Carefully insert the rear of the casing into the power
supply bay and slide the power supply back until its
connector meets the chassis backplane connector.

4Continue sliding the power supply back until the front
panel meets the front of the chassis. Do not force the
power supply into the bay. Otherwise you can damage the
connectors.
5Tighten the four captive screws, located at the four
corners of the power supply’s front panel. Be sure not to
overtighten the captive screws. If you use a screwdriver,
the torque used to tighten the screws must not exceed 2.3
inch pounds.
6Verify that the power supply’s on/off switch is in the
off ( O ) position.
7Remove the two screws on the top of the power cord
retainer with a Phillips-head screwdriver. Do not discard
these screws; you will need to reinstall them later.
8Slide the end of the power cord through the top portion
of the retainer until it stops.
9Plug the other end of the power cord into the power
supply’s socket. Make sure that the power cord is attached
securely to the outlet.

10 Use a Phillips-head screwdriver to attach the top
portion of the retainer with the two Phillips-head screws.
11 Once the power cord is secured in the retainer, plug
the power cord into an easily-accessible, properly
grounded outlet. Do not use an extension cord.
12 Install all remaining power supplies by repeating steps
1 through 11 for each power supply.
Note. For OmniSwitch 8800 switches using DC power,
the power cord connector snaps into the connector socket.
A cable retainer is not used.
Important. Do not turn on the power supplies at this time.
Using the Grounding Wrist Strap and Chassis
Grounding Lug
Because electrostatic discharge (ESD) can damage switch
components such as the Network Interface (NI) and Chassis
Management Modules, you must ground yourself properly
before continuing with the hardware installation.
For this purpose, Alcatel provides a grounding wrist strap and
a grounding lug located near the bottom-right of the chassis.
To properly ground yourself, follow the steps below.
1Fasten the provided grounding strap to your wrist.
2Insert the wrist strap’s connector pin (located at the end
of the strap’s tether) into the grounding lug near the
bottom-right of the chassis, as shown.

March 2005 Installing the Hardware 13
Important. For the grounding wrist strap to be effective
in eliminating ESD, the power supplies must be installed
in the chassis and plugged into grounded AC outlets as
described on page 10.
Installing the Network Interface (NI) and
Chassis Management Modules (CMMs)
Once you are properly grounded, you may begin installing the
Network Interface (NI) and CMM(s).
Note. See “Installing SFMs” on page 18 for information
on installing SFMs.
NI Modules
NI modules may be installed in any slot position from 1
through 16 in OS8800 switches.
CMMs
CMMs may be installed in slots A or B in OS8800 switches. A
minimum of one CMM is required for switch operations; the
second CMM provides redundancy.
In non-redundant configurations, the CMM may be installed in
either slot A or B. In redundant configurations, the CMM
installed in slot A will be designated primary by default. For
more information on redundancy, refer to page 52 or, for
detailed information, refer to your OmniSwitch 8800 Hard-
ware Users Guide.
NI modules cannot be installed in CMM slots A or B; like-
wise, CMMs cannot be installed in any NI slot position.
More Information on Slot Numbering. For a diagram
showing the chassis layout and slot positions, refer to
“Chassis Slot Numbering” on page 50.

Note. To further reduce exposure to electrostatic discharge
(ESD) and physical damage, do not remove more than one
module at a time from the factory packaging. Unpack one
module, immediately install the module in the chassis,
then repeat the sequence for another module.
Before beginning, note that the CMM modules and NI
modules slide into the chassis card guides differently. With
CMMs, the back of the module’s printed circuit board (which
is wider than the front side) initially provides the glide path.
When the printed circuit board narrows a sheet metal flange
continues the remaining glide path. With NIs, the edges of the
module’s printed circuit board slide into the guides.
CMM Glide Path
To install an NI or CMM module, follow the steps below.
1Holding the module in both hands, carefully slide it
into the chassis card guide. The component side of the
board should face right.
2The module should slide in easily. Do not force the
module into the slot. If any resistance is encountered,
ensure the module is aligned properly in the card guide.
Also, see the important note regarding chassis card guides
on page 14.
