•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 ventilation at the front, back, and sides of the switch. Refer to “Mounting the Switch” on page 7 for minimum clearance requirements. No clearance is necessary at the top or bottom of the chassis.

OmniSwitch 8800 switches have the following general electrical 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 remaining 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 Management Modules (CMMs) are packaged in separate boxes. In order to greatly reduce exposure to electrostatic 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 information 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.

4Continue pulling the power supply out until it is removed from the chassis.

5Set the power supply aside on a clean, static-free surface. You will need to re-install it later.

6Remove all remaining power supplies by repeating steps 1 through 5.

7Continue to “Lifting the Chassis” on page 7.

6 Installing the Hardware

March 2005

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 requirements, OmniSwitch 8800 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 and sides of the switch, as well as behind the switch’s fan unit (located at the top-rear of the chassis). The following topview diagram shows recommended minimum clearances for adequate airflow.

Installing the Hardware 7

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 manufacturer’s specifications.

•Refer to page 7 for important chassis airflow recommendations 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.

8 Installing the Hardware

March 2005

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.

6 Once 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.

7 Once the screws at the bottom of each bracket are secure, install the remaining screws. Be sure that all screws are securely tightened.

March 2005

Installing the Hardware 9

Stand-Alone

The OmniSwitch 8800 can be installed unmounted as a standalone 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.

Installing the Hardware 11

10 Use a Phillips-head screwdriver to attach the top portion of the retainer with the two Phillips-head screws.

11Once 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.

12Install all remaining power supplies by repeating steps

1through 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.

12 Installing the Hardware

March 2005

Chassis

Grounding Lug

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 Hardware Users Guide.

NI modules cannot be installed in CMM slots A or B; likewise, 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.

1 Holding the module in both hands, carefully slide it into the chassis card guide. The component side of the board should face right.

2 The 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.

3 When the module is nearly seated in the slot, be sure that the two extractor levers—one on top of the module and one on the bottom—are slightly opened (approximately 30 degrees). This allows the notch on each extractor lever to grasp the rail on the chassis. Once the notches have grasped the rail, press both extractor levers simultaneously until the module is firmly seated.

4 Once the module is firmly seated, secure the module to the chassis by tightening the two captive screws. 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.

5 Install all remaining modules by repeating steps 1 through 4 for each module.

Note. There is a small removal handle at the front of the MiniGBIC transceiver. To remove a MiniGBIC, carefully lift this handle; then, grasp the handle and carefully pull the MiniGBIC from the module.

Caution. The MiniGBIC should slide in easily. Do not force it into the slot. If any resistance is encountered, ensure the MiniGBIC is aligned properly. Forcing the MiniGBIC into the slot can damage the unit, as well as components on your GNI module.
