❒Product documentation
❒Options (as ordered)
Unpack the shipment and report any lost or damaged items to your shipping carrier or
Lucent representative.
Selecting a Location
The location you select for installing the system hardware must meet the following
requirements:
❒19-inch EIA-standard grounded rack or table capable of supporting at least 60 kg
(130 lb). A fully-loaded switch weighs 30 kg (65 lbs).
❒At least 2 inches (5.2 cm) on either side of the system, and from the rear of the
system, to allow adequate airflow through the system (Figure 1-1.).
Figure 1-1. Selecting a Location
❒AC power source(s) within 2 m (6 ft.) (separate sources, on separate circuits, if you
require maximum fault tolerance)
❒Ambient temperature between 0°C and 40°C (32°F to 104°F)
❒Relative humidity less than 95%, non-condensing
Air Flow

Installing the System
The process for installing the system requires the following tasks:
1. Preventing Electrostatic Discharge
2. Installing the Chassis
3. Installing the Modules
4. Installing the Cables
5. Ensuring that You Have Enough Power Available
6. Connecting the Power Supplies
7. Powering On the System
Note: The Cajun P550 switch requires 16MB RAM for proper functioning.
Preventing Electrostatic Discharge
Protect the modules against damage from electrostatic discharge (ESD) by using a
grounded ESD wrist strap while installing and removing modules. While installing the
P550 Cajun Switch:
1. Ground the unit. The unit is grounded through the power cord when it is
connected between the unit and the primary power source.
2. Lay out the static-dissipative work surface (ESD mat) on a flat surface.
3. Connect the ground cord assembly to the ESD mat and to the ground plug on the
switch fan tray.
4. Wear the ESD wrist strap and attach it to the ground cord assembly.
Installing the Chassis
The system can be installed by:
❒Rack Mounting the System
❒Installing the System on a Table Top

Unpacking and Installing the Cajun P550 Switch
1-4Cajun P550 Switch Installation Guide
Rack Mounting the System
A fully loaded P550 Cajun Switch weighs 30 kg (65 lbs). Safe rackmount installation
requires three people: two to lift the system into place, and a third to screw the system to
the rack using a Phillips-head screwdriver.
WARNING:Do not use the handles on the power supplies or fan assembly to lift the
system.
To rack mount the system:
1. Install the rack mount flanges onto the system (Figure 1-2.).
Figure 1-2. Rack Mounting the Switch
2. Check that all pre-installed modules are securely installed:
• Check that the supervisor module is firmly installed.
• Check that the power supply and fan are securely in place.
• Tighten the large black screws on the module, power supply, and fan tray
faceplates.
3. With one person at each end of the system, lift the system into position. Use the
supplied screws to install the system into the rack (Figure 1-3.).

Installing the System on a Table Top
To install the system on a table top:
WARNING:Do not use the handles on the power supplies or fan assembly to lift the
system.
1. Place the system on a surface that supports at least 60 kg (130 lb). The switch itself
weighs about 30 kg (65 lbs) fully loaded.
2. Apply the supplied rubber feet to the bottom of the unit, placing the feet about 1.3
cm (1/2 in.) from each corner of the unit (Figure 1-4.).

3. Check that all pre-installed modules are securely installed:
• Check that the supervisor module is firmly installed
• Check that the power supply and fan are securely in place
• Tighten the large black screws on the module, power supply, and fan tray
faceplates.
Installing the Modules
To install modules in the system chassis:
1. Carefully remove each module from its box, leaving the module in its antistatic
wrapping.
2. After taking appropriate antistatic precautions, as described in "Preventing
Electrostatic Discharge”, earlier in the chapter, carefully remove the module from
the antistatic wrap.
3. Insert the module into the system (Figure 1-5.).
Figure 1-5. Inserting the Modules
4. Push the module most of the way into the system chassis. Use the ejectors to insert
the module into the system backplane (Figure 1-6.).

5. Tighten the black captive screws.
Auto Negotiation Issues
You may experience difficulties with auto-negotiation between some versions of the
10/100Base-TX module and adapter cards using physical interfaces manufactured by
National Semiconductor. The symptom is loss of connectivity.
You can address this problem by either disabling auto-negotiation and manually
configuring the speed and duplex of the mirror port and network card, or using a patch
cable longer than 5 meters.
Installing the Cables
Install appropriate cables for your network configuration. P550 Cajun switch cable types
include:
❒Fiber cables with SC-type connectors
❒Straight-through Category 5 cables with male RJ-45 connectors (end station/NIC
(network interface card) card connections). All I/O ports are crossed over internally
so you can use straight-through cables to attach to end stations.
❒Crossover cables with male RJ-45 connectors (switch-to-switch connections).
The types of cable for the ethernet console (out-of-band) are different. Refer to Chapter
2, “Configuring the Cajun Switch (Layer 2 & Layer 3),” for more information.

half-duplex networks using Ethernet repeaters, you must also consider
maximum network diameter, which is not discussed in this document.

Ensuring that You Have Enough Power Available
Each power supply powers approximately three I/O modules. It takes two power
supplies to power a full chassis. Using three power supplies ensures that the system has
fault-tolerant load-sharing power capabilities.
Use Table 1-5 for the precise power values:
Note: See the instruction sheet included with the power supply for power supply
installation instructions.

Connecting the Power Supplies
Before connecting the power cords:
❒Make sure that all of the power supplies are seated firmly, with the captive screws
tightened.
❒Make sure that all of the ON/OFF switches on the power supplies are OFF.
❒If you are using multiple power supplies to ensure fault tolerance, make sure that
there is a dedicated power circuit available for each supply. The separate power
sources help ensure operation when the power source itself fails.
To connect the power supplies:
1. Plug the power cord into each power supply.
2. Plug the power cord into an AC outlet.
Powering On the System
To power on the system:
1. Check all connections.
2. Turn on the power supplies by switching on the power switches on each supply.
Power-On Sequence
As the system powers on:
❒Lucent P550 Cajun Switch Agent (M5500-SUP) v4.x.x displays on the 8-character
LED display on the front panel of the switch.
❒On properly functioning modules, Port LEDs will cycle from yellow to normal
operating status as the system continues through its power-on diagnostics.
When the system has completed running its internal diagnostics:
❒The 8-character LED display should read:
