CHAPTER
1
Product Overview
This chapter describes the Catalyst 8540 chassis and provides an overview of the chassis
components. The Catalyst 8540 is a 13-slot, modular chassis with optional dual,
fault-tolerant, load-sharing AC or DC power supplies. (See Figure 1-1.) In the event of a
failure of input power to one supply, or the failure of one power supply, the redundant
power option ensures uninterrupted operation.
The chassis can contain the following components:
• One route processor placed in slot 4 of the chassis.
• Up to eight hot-swappable line modules or port adapters placed in slots 0 through 3 and
slots 9 through 12.
• Up to three hot-swappable switch modules placed in slots 5 and 7. Slot 6 can contain a
switch module that acts as a backup if either module fails.

Catalyst 8540 Chassis Installation Guide
Site Planning
This chapter describes how to prepare your site for installation of the chassis and discusses
the site environment requirements. This chapter contains the following sections:
• Site Preparation Guidelines
• Environmental Monitoring Functions
• Site Requirements
Site Preparation Guidelines
Planning the proper location and layout of your equipment rack or wiring closet is essential
for successful system operation. Equipment placed in an inadequately ventilated area can
cause system overtemperature conditions. In addition, poor equipment placement can make
chassis panels inaccessible and difficult to maintain. Follow these precautions when
planning your equipment locations and connections:
CHAPTER
2
• Keep the front of the chassis free from obstructions and away from the exhaust air of
other equipment. Remember that electrical equipment generates heat, and ambient room
temperature alone might not be adequate to cool equipment to acceptable operating
temperatures.
• Secure the placement of all chassis panels, modules, and any module slot fillers. The fan
assembly pulls cooling air across the line modules. A loose panel allows too much air
to escape and can redirect the airflow away from active line modules.
Site Planning 2-1
Environmental Monitoring Functions
Warning This unit is intended for installation in restricted access areas. A
restricted access area is where access can only be gained by service personnel
through the use of a special tool, lock and key, or other means of security, and is
controlled by the authority responsible for the location.
Environmental Monitoring Functions
You can maintain normal system operation by identifying and resolving adverse conditions
before the system fails by using environmental monitoring and reporting functions.
Environmental monitoring functions constantly monitor the internal air temperature of the
chassis. Each power supply monitors its own voltage and shuts down if it detects a critical
condition within the power supply. The reporting functions retrieve and display the present
values of measured parameters. If any of the monitored parameters exceed defined
thresholds, the reporting functions display alarms on the console.
The environmental monitoring functions use two levels of status conditions to monitor the
system: normal and alarm. The processor monitors the temperature inside the module
compartment, and the power supplies use the normal and alarm levels to monitor voltages.
Table 2-1 lists temperature thresholds for the processor-monitored levels:
• Normal—All monitored parameters are within normal tolerances.
2-2
• Alarm—An out-of-tolerance temperature or voltage condition exists. The system might
not continue operation. If a voltage measurement reaches this level, the power supply
can shut down the system. Immediate action is required.
Table 2-1 Processor-Monitored Temperature Thresholds
Parameter Normal Alarm
Temperature 0–55°C> 55°C
The power supply monitors its own internal temperature and voltages. The power supply is
either within tolerance (normal) or out of tolerance (alarm). If an internal power supply
temperature or voltage reaches the alarm level, the output fail LED may be unreliable and
the power supply can shut down the system.
Catalyst 8540 Chassis Installation Guide
Site Requirements
This section contains the following topics:
• AC and DC Power
• Interference Considerations
• Equipment Racks
• Site Environment
• Equipment Rack Ventilation
• Power
• Network Connections
AC and DC Power
The 1300W AC power supply uses a power factor corrector (PFC) that allows the power
supply to operate on input voltage and current within the ranges of 90 to 264 VAC and 50
to 60 Hz.
A second, identical power supply is also present in the chassis configured with an optional
redundant power supply. Table A-1 in the appendix “Chassis and Power Supply
Specifications” lists system power specifications, including input voltage and operating
frequency ranges.
Site Requirements
The Catalyst 8540 relies on protective devices in the building installation for protection
against short-circuit, overcurrent, and earth fault. Ensure that the protective devices in the
building installation are properly rated to protect the system, and that the protective devices
comply with national and local codes.
Site Planning 2-3
Site Requirements
The following warnings apply to DC power supplies:
Warning A readily accessible two-poled disconnect device must be incorporated
in the fixed wiring.
Before connecting each unit, note its power consumption rating in Table A-1 in the
appendix “Chassis and Power Supply Specifications.”
Interference Considerations
When wires are run for any significant distance in an electromagnetic field, interference can
occur between the field and the signals on the wires. As a result:
• Bad plant wiring can result in radio frequency interference (RFI).
• Strong electromagnetic interference (EMI), especially when it is caused by lightning or
radio transmitters, can destroy the signal drivers and receivers in the chassis, and can
even create an electrical hazard by conducting power surges through lines and into
equipment.
Note To predict and remedy strong EMI, you might need to consult RFI experts.
Equipment Racks
A rack-mount kit is provided for mounting the chassis in a standard 19-inch (48 cm)
equipment rack. The rack-mount kit is not suitable for racks with obstructions (such as a
power strip) that could impair access to the processor and power supplies. Figure 2-1 shows
the chassis footprint and outer dimensions.

19.75"
(48.2 cm)
17.75"
(43.13 cm)
To use the rack-mount kit, your equipment rack must meet the following requirements:
• The width of the rack, between the two front mounting strips or rails, must be
17.75 inches (43.13 cm).
• The depth of the rack, between the front and rear mounting strips, must be at least
19.25 inches (48.2 cm) but not more than 32 inches (80 cm).
Site Planning 2-5
Site Requirements
• The height of the chassis is approximately 25 inches (62.5 cm). The rack must have
sufficient vertical clearance to allow insertion of the chassis.
When planning your rack installation, follow these guidelines:
• Allow at least 3 feet (1 m) of clearance in front of the rack for maintenance and removal
of the route processor, line modules, power supplies, and the fan assembly.
• Note that the ports for cooling air are located on the front, rear, and both sides of the
chassis, so multiple chassis can be rack-mounted with little or no vertical clearance.
However, avoid placing the chassis in an overly congested rack.
Warning To prevent overheating the chassis, do not operate it in an area that
exceeds the maximum recommended ambient temperature of 104°F (40°C). To
prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the
ventilation openings.
• Consider the equipment and cabling already installed in the rack. Ensure that cables
from other equipment do not obstruct the airflow through the chassis or impair access
to the power supplies or line modules. Route cables away from field-replaceable
components to avoid having to disconnect cables unnecessarily to perform equipment
maintenance or upgrades.
2-6
• Install heavier equipment in the lower half of the rack to maintain a low center of
gravity.
• Ensure that the shelf you place the chassis on can support the weight and dimensions of
the chassis. Use the chassis footprint, shown in Figure 2-1 if you are designing a
customized shelf.
Caution Never install the chassis in an enclosed rack that is not properly
ventilated or air-conditioned.
Catalyst 8540 Chassis Installation Guide
Equipment Racks
Follow these guidelines to help ensure your safety:
• Mount the chassis at the bottom of the rack.
• If the rack has stabilizing devices, install the stabilizers before mounting or servicing
the unit in the rack.
• The chassis must always be mounted horizontally, as shown in Figure 2-2.
In addition to the preceding guidelines, review the precautions in the section “Equipment
Rack Ventilation” later in this chapter.

Site Planning 2-7
Site Requirements
Site Environment
The chassis operates as a standalone system mounted in a rack in a secure wiring closet.
The environment must be dry, clean, well-ventilated, and air-conditioned. An internal fan
assembly pulls cooling air through the chassis from the front and right side (intake) to the
rear and left side (exhaust). (See Figure 2-3.) The flow of ambient air must be maintained
to ensure normal operation. If the airflow is blocked or restricted, or if the intake air exceeds
104°F, an overtemperature condition can occur. Under extreme conditions, the
environmental monitor can shut down the system to protect the system components.

To ensure normal operation and avoid unnecessary maintenance, plan your site
configuration and prepare your site before installation. After installation, make sure that the
site maintains an ambient temperature of 32 to 104°F (40°C), and that the area around the
chassis is free of dust.

Site Environment
If the room temperature exceeds 104°F (40°C), the air temperature inside the chassis could
overheat the unit. Any of the following can inhibit airflow and cause overheating:
• The wiring closet or rack in which the chassis is mounted is not properly ventilated.
• The exhaust of one device is placed so it enters the air intake vent of the chassis.
• The chassis is the top unit in an unventilated rack.
Multiple chassis can be rack-mounted with no clearance above and below the chassis.
When mounting a chassis in a rack with other equipment or when placing a chassis on the
floor adjacent to other equipment, ensure that the exhaust from other equipment does not
blow into the intake vent (lower front panel) of the chassis.
Table 2-2 lists the operating and nonoperating environmental site requirements. To
maintain normal operation and ensure high system availability, maintain an ambient
temperature at your site. The chassis operates in the ranges listed in Table 2-2; however, a
measurement that is approaching the minimum or maximum of a range indicates a potential
problem. You can maintain normal operation by anticipating and correcting environmental
anomalies before they exceed the maximum operating range.

Equipment Rack Ventilation
If you plan to install the chassis in an equipment rack, follow these precautions and
guidelines that are provided in the section “Equipment Racks” earlier in this chapter to
avoid overtemperature conditions:
• Install the chassis in an enclosed rack only if it has adequate ventilation or an exhaust
fan. Use an open rack whenever possible.
• Note that a ventilation system that is too powerful in a closed rack might prevent cooling
by creating negative pressure around the chassis and redirecting the air away from the
chassis intake vent. If necessary, operate the chassis with the rack open.
• Use baffles inside the enclosed rack to assist in cooling the chassis.
• Do not place equipment near the bottom of a rack, because it might generate excessive
heat that is drawn upward and into the intake ports of equipment above, leading to
overtemperature conditions in the chassis at or near the top of the rack.
