Feature Description
Fan assembliesThe chassis has five individual fan assemblies. Each fan assembly
has an LED associated with it providing fan status.
NoteThe chassis normally operates with all five fan assemblies
running. However, the chassis can operate for an indefinite
period of time with only four fans running. If you operate
the chassis with only four fans, you do not have fan
redundancy meaning that any additional fan assembly
failures will result in the chassis shutting down.
Power supply baysTwo power supply bays are located on the rear of the chassis. On
chassis that are equipped with only one power supply, the power
supply can be installed in either power supply bay. The second,
unused, power supply bay must have a power supply blank panel
(part no. C4KX-PWR-BLANK=) installed to maintain air
circulation through the chassis and to maintain EMI integrity.
NoteThe chassis supports all combinations of AC-input and
DC-input power supplies: two AC-input power supplies,
two DC-input power supplies, or one AC-input power
supply and one DC-input power supply.

Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals.
Avoid using such interconnection methods, unless the exposed metal parts are located within a
restricted access location and users and service people who are authorized within the restricted
access location are made aware of the hazard. A restricted access area can be accessed only
through the use of a special tool, lock and key or other means of security.
Site Requirements
The following sections describe the basic site requirements that you should be aware of as you prepare
to install your Catalyst 4500-X series switch:
• Rack-Mounting Guidelines, page 16
• Temperature, page 17
• Airflow, page 18
• Humidity, page 19
• Altitude, page 19
• Dust and Particulates, page 19
• Corrosion, page 20
• Electromagnetic and Radio Frequency Interference, page 20
A rack-mount kit (C4948E-ACC-KIT) is included in your switch chassis accessory kit for mounting the
switch in a standard 19-inch (48.3 cm) equipment rack.
NoteThis kit might not suitable for use in equipment racks with obstructions (such as power strips) that could
impair access to the switch.
Before rack-mounting the switch, ensure the following:
• The width of the rack, between the two front-mounting strips or rails, must be 17.75 inches
(45.09 cm).
• The depth of the rack, between the front- and rear-mounting strips, must be at least 19.25 inches
(48.9 cm) but not more than 32.5 inches (82.5 cm).
• The rack must have sufficient vertical clearance to insert the chassis. The chassis height is 1 U
(1.75 inches (4.4 cm)).
16
Catalyst 4500-X Series Switch Installation Note
OL-24795-01
• The equipment rack is stable, sturdy, and is in no danger of tipping over.
–
Install heavier equipment in the lower half of the rack to maintain a low center of gravity and
prevent the rack from becoming top-heavy and tipping over.
• The equipment rack is properly ventilated.
–
Install the chassis in an enclosed rack only if it has adequate ventilation or an exhaust fan; use
an open rack whenever possible.
–
Ensure that the ambient temperature of the rack environment does not exceed a maximum
temperature of 104° F (40° C). If the switch is installed in a closed or multiunit rack assembly,
the ambient operating temperature of the rack environment might be higher than the ambient
room temperature.
–
Ensure that the ventilation system in a closed rack does not 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.
–
Ensure that equipment installed near the bottom of a rack does not generate excessive heat,
which can be drawn upward and into the air intakes of equipment above. This situation can
cause overtemperature conditions in the chassis at or near the top of the rack.
–
Consider the equipment and cabling that is already installed in the rack. Ensure that cables from
other equipment will not obstruct the airflow through the chassis or impair access to the power
supplies or switching modules. Route cables away from field-replaceable components to avoid
disconnecting cables unnecessarily for equipment maintenance or upgrades.
Site Requirements
Temperature
–
Allow at least 3 to 4 feet (91 to 122 cm) of clearance behind the rack for maintenance and
removal of switch assemblies. If the rack is mobile, you can push it back within 1 foot
(30.45 cm) of a wall or cabinet for normal operation and pull it out when necessary for
maintenance.
Temperature extremes can cause a system to operate at reduced efficiency and cause a variety of
problems, including premature aging and failure of chips, and failure of mechanical devices. Extreme
temperature fluctuations can cause chips to become loose in their sockets. Observe the following
guidelines:
• Ensure that the system is operating in an environment no colder than 50°F (10°C) or hotter than
104°F (40°C).
• Ensure that the chassis has adequate ventilation.
• Use proper air circulation management techniques. Chassis mounted higher in a rack enclosure are
susceptible to higher ambient air temperatures due to the heat generated from chassis that are
mounted below the chassis in the rack.
• Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as insulation.
• Do not place the chassis where it will receive direct sunlight, particularly in the afternoon.
• Do not place the chassis next to a heat source of any kind, including heating vents.
OL-24795-01
Catalyst 4500-X Series Switch Installation Note

Site Requirements
Airflow
• Ensure that all slots and openings on a chassis remain unobstructed, especially the fan assembly vent
at the back of the chassis. Adequate ventilation is particularly important at high altitudes where the
air is thinner.
• Clean the installation site at regular intervals to avoid buildup of dust and debris, which can cause a
system to overheat.
• Allow a 2-hour warm-up period to bring the chassis up to normal operating temperature before
turning it on for chassis that have been exposed to abnormally cold temperatures.
Failure to observe these guidelines can damage internal chassis components.
NoteThe Catalyst 4500-X series switches are equipped with internal air temperature sensors that are triggered
at 104°F (40°C) generating a minor alarm and at 131°F (55°C) generating a major alarm.
The Catalyst 4500-X series switch is designed to be installed in an environment where there is a
sufficient volume of air available to cool the chassis and the power supplies. Any constraints placed on
the free flow of air through the chassis or an elevated ambient air temperature can cause the switch to
overheat and shut down.
To maintain proper air circulation through the switch chassis, we recommend that you maintain a
minimum 6-inch (15 cm) separation between a wall and the chassis hot air exhaust. Failure to maintain
adequate spacing between chassis can cause the switch chassis that is drawing in the hot exhaust air to
overheat and fail.
If your chassis is equipped with only one power supply (either AC-input or DC-input), you must have a
blank power supply cover (part no. C4KX-PWR-BLANK=) installed over the empty power supply bay
to maintain proper airflow through the chassis.
If your chassis does not have the uplink module installed, you must have a blank uplink module cover
(part no. C4KX-NM-BLANK=) installed over the empty uplink module bay to maintain proper airflow
through the chassis.
If you are installing your Catalyst 4500-X series switch chassis in an enclosed or partially enclosed rack,
we strongly recommend that you verify that your site meets the following guidelines:
• Verify that the ambient air temperature within the enclosed or partially enclosed rack is within the
chassis operating temperature limits. After installing the chassis in the rack, power up the chassis
and allow the chassis temperature to stabilize (approximately 2 hours). Measure the ambient air
temperature at the chassis air intake grill and at the chassis air exhaust grill by positioning an
external temperature probe approximately 1 inch (2.5 cm) away from the grills.
–
If the ambient intake air temperature is less than 104°F (40°C), the rack meets the intake air
temperature criterion.
–
If the ambient intake air temperature exceeds 104°F (40°C), the system might experience minor
temperature alarms and is in danger of overheating. Prolonged operation at a temperature in
excess of 104°F (40°C) might severely affect the long-term reliability of the equipment.
–
If the ambient intake air temperature equals or is greater than 131°F (55°C), the system will
experience a major temperature alarm and shut down.

Catalyst 4500-X Series Switch Installation Note
OL-24795-01
Humidity
Site Requirements
• Verify that the enclosed or partially enclosed rack allows an adequate flow of air through the switch
chassis as follows:
–
If the difference between the measured intake air temperature and the exhaust air temperature
does not exceed 10°C, there is sufficient airflow in the rack.
–
If the difference in air temperature exceeds 10°C, there is insufficient airflow to cool the chassis.
NoteThe 10°C temperature differential between the intake and the exhaust must be determined by
taking measurements using external digital temperature probes. Do not use the chassis internal
temperature sensors to measure the temperature differential.
• Plan for future growth. Your Catalyst 4500-X series switch currently installed in an enclosed or
partially enclosed rack might meet ambient air temperature and airflow requirements now. However,
if you add more chassis or other equipment to the rack, the additional heat generated might cause
the ambient air temperature within the rack to exceed 104°F (40°C) and can cause minor alarms.
High-humidity conditions can cause moisture migration and penetration into the system. This moisture
can cause corrosion of internal components and degradation of properties such as electrical resistance,
thermal conductivity, physical strength, and size. Extreme moisture buildup inside the system can result
in electrical shorts, which can cause serious damage to the system. Each system is rated to operate at 8
to 80 percent relative humidity, with a humidity gradation of 10 percent per hour. In storage, a system
can withstand from 5 to 95 percent relative humidity. Buildings in which climate is controlled by
air-conditioning in the warmer months and by heat during the colder months usually maintain an
acceptable level of humidity for system equipment. However, if a system is located in an unusually
humid location, a dehumidifier can be used to maintain the humidity within an acceptable range.
Altitude
Operating a system at high altitude (low pressure) reduces the efficiency of forced and convection
cooling and can result in electrical problems related to arcing and corona effects. This condition can also
cause sealed components with internal pressure, such as electrolytic capacitors, to fail or perform at
reduced efficiency. Each system is rated to operate at altitudes from –50 to 6500 feet (–16 to
1981 meters) and can be stored at altitudes of –50 to 35,000 feet (–16 to 10,668 meters).
Dust and Particulates
Fans cool the power supplies and the system components by drawing in room temperature air, circulating
the air through the power supplies and the chassis, and exhausting the heated air out through various
openings in the chassis. However, fans also ingest dust and other particulates, causing contaminant
buildup on the fan blades and in the system, which create a thermal blanket on components increasing
the internal chassis temperature.

Site Requirements
A clean operating environment can greatly reduce the negative effects of dust and other particulates. The
standards listed below provide guidelines for acceptable working environments and acceptable levels of
suspended particulate matter:
• Network Equipment Building Systems (NEBS) GR-63-CORE
• National Electrical Manufacturers Association (NEMA) Type 1
• International Electrotechnical Commission (IEC) IP-20
Corrosion
Corrosion of system connectors is a gradual process that can eventually lead to intermittent failures of
electrical circuits. The oil from a person’s fingers or prolonged exposure to high temperature or humidity
can corrode the gold-plated edge connectors and pin connectors on various components in the system.
To prevent corrosion, avoid touching contacts on boards and cards, and protect the system from extreme
temperatures and moist, salty environments.
Electromagnetic and Radio Frequency Interference
Electromagnetic interference (EMI) and radio frequency interference (RFI) from a system can adversely
affect devices such as radio and television (TV) receivers operating near the system. Radio frequencies
emanating from a system can also interfere with cordless and low-power telephones. Conversely, RFI
from high-power telephones can cause spurious characters to appear on the system monitor. RFI is
defined as any EMI with a frequency above 10 kilohertz (kHz). This type of interference can travel from
the system to other devices through the power cable and power source or through the air like transmitted
radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the
amount of EMI and RFI emitted by computing equipment. Each system meets these FCC regulations. To
reduce the possibility of EMI and RFI, follow these guidelines:
• Operate the system with the chassis covers installed.
• Ensure that an unused power supply bay has the blank cover plate installed.
• If you do not have the optional network uplink module installed, make sure that the unused bay has
a blank panel installed.
When wires are run for any significant distance in an electromagnetic field, interference can occur
between the field and the signals on the wires. This fact has two implications for the construction of plant
wiring:
• Bad wiring practice can result in radio interference emanating from the plant wiring.
• Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal
drivers and receivers in the chassis, and even create an electrical hazard by conducting power surges
through lines into equipment.
20
NoteTo predict and remedy strong EMI, you may also need to consult experts in radio frequency interference
(RFI).
If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the
plant wiring is unlikely to emit radio interference.
Catalyst 4500-X Series Switch Installation Note
OL-24795-01
CautionCategory 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the
dielectric properties of the materials used in their construction. We recommend that you momentarily
ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting
them to the port.
If the wires exceed the recommended distances, or if wires pass between buildings, give special
consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by
lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors
to destroy electronic devices. If you previously have had similar problems, you might want to consult
experts in electrical surge suppression and shielding.
Shock and Vibration
Catalyst 4500-X series switches have been shock- and vibration-tested for operating ranges, handling,
and earthquake standards to NEBS (Zone 4 per GR-63-Core). These tests have been conducted in
earthquake environment and criteria, office vibration and criteria, transportation vibration and criteria,
and packaged equipment shock.
Site Requirements
Power Source Interruptions
Systems are especially sensitive to variations in voltage supplied by the AC power source. Overvoltage,
undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail.
To protect against these types of problems, power cables should always be properly grounded. Also,
place the system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical
equipment). Besides these appliances, the greatest threats to a system power supply are surges or
blackouts that are caused by electrical storms. Whenever possible, turn off the system and any
peripherals, and unplug them from their power sources during thunderstorms. If a blackout occurs—even
a temporary one—while the system is turned on, turn off the system immediately and disconnect it from
the electrical outlet. Leaving the system on may cause problems when the power is restored; all other
appliances left on in the area can create large voltage spikes that can damage the system.
System Grounding
We recommend that you install a NEBS-compliant system ground as part of the chassis installation
process. Chassis installations that rely only on the AC third-prong ground are insufficient to properly
and adequately ground the systems. The chassis comes with a ground lug and two M4 bolts as part of
the accessory kit. The lug attaches to the chassis grounding pad with the two bolts. A properly sized
copper wire (not provided) should be used to connect the ground lug to the NEBS-compliant building
ground.
Proper grounding practices ensure that the buildings and the installed equipment within them have
low-impedance connections and low-voltage differentials between chassis. When you include
NEBS-compliant system grounds, you reduce or prevent shock hazards, greatly reduce the chances of
equipment damage due to transients, and substantially reduce the potential for data corruption.
Without proper and complete system grounding, you run the risk of increased component damage due to
ESD. Additionally, you have a greatly increased chance of data corruption, system lockup and frequent
system reboot situations by not using a system (NEBS compliant) ground.

NoteIn all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC)
requirements or local laws and regulations. A 6 AWG grounding wire is preferred from the chassis to the
rack ground or directly to the common bonding network (CBN). The equipment rack should also be
connected to the CBN with 6 AWG grounding wire.
Maintaining Safety with Electricity
When working on electrical equipment, follow these guidelines:
• Do not work alone if potentially hazardous conditions exist anywhere in your work space.
• Never assume that power is disconnected from a circuit; always check the circuit before working on
it.
• Look carefully for possible hazards in your work area, such as damp floors, ungrounded power
extension cables, frayed or damaged power cords, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
–
Use extreme caution; do not become a victim yourself.
–
Disconnect power from the system.
–
If possible, send another person to get medical aid. Otherwise, assess the condition of the
victim, and then call for help.
–
Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
• Use the product within its marked electrical ratings and product usage instructions.
• Install the product in compliance with local and national electrical codes.
OL-24795-01
Catalyst 4500-X Series Switch Installation Note

Site Requirements
• If any of the following conditions occur, contact the Cisco Technical Assistance Center:
–
The power cable or plug is damaged.
–
An object has fallen into the product.
–
The product has been exposed to water or other liquids.
–
The product has been dropped or shows signs of damage.
–
The product does not operate correctly when you follow the operating instructions.
• Use the correct external power source. Operate the product only from the type of power source
indicated on the electrical ratings label. If you are not sure of the type of power source required,
consult the Cisco Technical Assistance Center or a local electrician.
• Use approved power cables only. You have been provided with one or more power cables with your
chassis power supply that are intended for use in your country, based on the shipping location.
Should you need to purchase additional power cables, ensure that they are rated for the product and
for the voltage and current marked on the product’s electrical ratings label. The voltage and current
rating of the power cable should be greater than the ratings marked on the label.
• To help prevent electrical shock, plug all power cables into properly grounded electrical outlets.
• Observe power strip ratings. Make sure that the total current rating of all products that are plugged
into the power strip does not exceed 80 percent of the power strip rating.
• Do not modify power cables or plugs yourself. Consult with a licensed electrician or your power
company for site modifications. Always follow your local and national wiring codes.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly
handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are
fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral
components of the carrier. Although the metal carrier helps to protect the board from ESD, always use
an ESD grounding strap when handling modules.
To prevent ESD damage, follow these guidelines:
• Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin. ESD
grounding straps are available with banana plugs, metal spring clips, or alligator clips. If you choose
to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap equipped with
an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper
grounding point for the ESD wrist strap.
NoteThis system ground is also referred to as the network equipment building system (NEBS)
ground.
• If your chassis does not have the system ground attached, you must install the system ground.
24
Catalyst 4500-X Series Switch Installation Note
OL-24795-01
Power Requirements
After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:
Step 1Attach the ESD wrist strap to bare skin as follows:
a. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and
unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap
so that it makes good contact with your bare skin.
b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove
the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your
bare skin.
Step 2Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal
spot (unpainted surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so
that any built-up static charge is then safely dissipated to the entire rack.
Step 3Attach either the spring clip or the alligator clip to the ground lug screw as follows:
a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws
open, position the spring clip to one side of the system ground lug screw head, and slide the spring
clip over the lug screw head so that the spring clip jaws close behind the lug screw head.
NoteThe spring clip jaws do not open wide enough to fit directly over the head of the lug screw
or the lug barrel.
b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip
directly over the head of the system ground lug screw or to the system ground lug barrel.
CautionFor safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohm (Mohm).
Power Requirements
When preparing your site for the switch installation, follow these general requirements:
• In systems configured with two power supplies, connect each of the two power supplies to a separate
input power source. If you fail to do this, your system might be susceptible to total power failure
due to a fault in the external wiring or a tripped circuit breaker.
• To prevent a loss of input power, be sure that the total maximum load on each source circuit is within
the current ratings of the wiring and breakers.
• In some systems, you may decide to use an uninterruptible power supply (UPS) to protect against
power failures at your site. Be aware when selecting a UPS that some UPS models that use
ferroresonant technology can become unstable when operating with the power supplies which use
power factor correction (PFC). This can cause the output voltage waveform to the switch to become
distorted resulting in an undervoltage situation in the system.

Power Connection Guidelines for AC-Powered Systems
This section provides some basic guidelines for connecting the AC power supplies to the site power
source:
• It is recommended that each chassis power supply should have a separate, dedicated branch circuit.
–
(North America)—It is recommended that the AC-input power supply operate on a 15 A circuit.
Statement 1045
–
(International)—Circuits should be sized according to local and national codes.
• If you are using a 200/240 VAC power source in North America, the circuit must be protected by a
two-pole circuit breaker.
• Make sure that your power cord can easily reach from the chassis power supply to the source AC
outlet. The AC power cords come in standard lengths of 6 feet (1.8 meters) and 8 feet 2 inches
(2.5 m). The source AC outlet should be easily accessible.
• The AC power receptacles used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground at the service
equipment.
Power Connection Guidelines for DC-Powered Systems
This section provides the basic guidelines for connecting the Catalyst 4500-X series switch DC-input
power supplies to the site power source:
• All power connection wiring should conform to the rules and regulations in the National Electrical
Code (NEC), as well as any local codes.
• The DC return must remain isolated from the system frame and the chassis (DC-I).
26
Catalyst 4500-X Series Switch Installation Note
OL-24795-01
• For DC power cables, we recommend that you use commensurately rated, high-strand-count copper
wire cable. Connection to the DC-input power supply requires one source DC (–), and one source
DC return (+). The length of the cables depends on your switch location. The cables required to
attach the source DC cables to the power supply are not available from Cisco Systems; they are
available from any commercial cable vendor.
• The color coding of the source DC power cable leads depends on the color coding of the site DC
power source. Because there is no color code standard for source DC wiring, you must ensure that
the power cables are connected to the DC-input power supply terminal block in the proper (+) and
(–) polarity. In some cases, the source DC cable leads might have a positive (+) or a negative (–)
label. This label is a relatively safe indication of the polarity, but you must verify the polarity by
measuring the voltage between the DC cable leads. When making the measurement, the positive (+)
lead and the negative (–) lead must always match the (+) and (–) labels on the DC-input power
supply terminal block.
• The circuit breaker is considered to be the disconnect device and should be easily accessible.
• The circuit must be protected by a dedicated two-pole circuit breaker. The circuit breaker should be
sized according to the power supply input rating and local or national code requirements.
Cabling Requirements
Power Requirements
CautionThe intrabuilding port(s) of the equipment or subassembly is suitable for connection to intrabuilding or
unexposed wiring or cabling only. The intrabuilding port(s) of the equipment or subassembly must not
be metallically connected to interfaces that connect to the Outside Plant (OSP) or its wiring. These
interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.
When running power and data cables together in overhead cable trays or subfloor cable trays, be aware
of the following caution:
CautionWe recommend that power cabling runs and other potential noise sources be located as far away as
practical from LAN cabling that terminates on Cisco equipment. In situations, where this type of long
parallel cable runs exist, which cannot be separated by at least 3.3 feet (1 meter), we recommend that
you shield these potential noise sources. To avoid interference, the source should be shielded by housing
it in a grounded metallic conduit.
Also be aware of the following caution concerning the use of Category 5e and Category 6 Ethernet
cables:
CautionCategory 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the
dielectric properties of the materials used in their construction. We recommend that you momentarily
ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting
them to the port.

Installing the Chassis Using the Optional C4948E-BKT-KIT= Rack-Mount Kit
The C4948E-BKT-KIT= four-post rack mount kit is an optional (separately orderable) rack-mount kit.
The C4948E-BKT-KIT= kit is used with the standard rack-mount brackets and attachment hardware
supplied as part of the Catalyst 4500-X switch accessory kit to install the chassis in a four-post rack. To
install the Catalyst 4500-X series switch in a four-post rack using the optional C4948E-BKT-KIT=
rack-mount kit, follow these steps:
Step 1Prepare for installation:
a. Place the chassis on the floor or on a sturdy table as close as possible to the rack. Leave enough
clearance to allow you to move around the chassis.
b. Use a tape measure to measure the depth of the rack. Measure from the outside of the front mounting
posts to the outside of the rear mounting strip. The four-post rack depth must be at least 19.25 inches
(48.9 cm) but not more than 32.5 inches (82.5 cm).
c. Measure the space between the inner edges of the left front and right front mounting posts to ensure
that it is 17.75 inches (45.09 cm) wide. (The chassis is 17.25 inches [43.8 cm] wide and must fit
between the mounting posts.)

Step 2Verify that the standard rack-mount brackets that ship with the chassis accessory kit are installed on the
front sides of the chassis. (See Figure 3, top view.) Using a torque wrench, verify that all eight bracket
mounting screws are tightened to between 8 inch-lbs and 10 inch-lbs (0.90 Newton-meters to
1.13 Newton-meters).
Step 3Open the optional four-post rack-mount kit and remove the four brackets (two chassis attach brackets
and two slider brackets) and the mounting hardware.
Step 4Attach the left and right brackets to the rear of the switch chassis using eight M4 Phillips-head screws
(four on each side) provided in the rack-mount kit. (See Figure 10.) Make sure that you use all eight
screws. Using a torque wrench, tighten the eight screws to between 8 inch-lbs and 10 inch-lbs
(0.90 Newton-meters to 1.13 Newton-meters).
NoteSome equipment racks have a power strip along the length of one of the rear posts. If the rack
has this feature, consider the position of the strip when planning fastener points.
Step 5Slide the two slider brackets into the chassis attach brackets. (See Figure 10.)

Step 6Install the chassis in the four-post rack as follows:
332187
a. Position the chassis in the rack (see Figure 11):
–
If the chassis front panel is in the front of the rack, insert the rear of the chassis between the
mounting posts.
–
If the rear of the chassis is in the front of the rack, insert the front of the chassis between the
mounting posts.
b. Adjust the two slider brackets either in or out so that the slider bracket flanges are in contact with
the rack posts.
c. Align the mounting holes in the front and rear rack-mount brackets with the mounting holes in the
equipment rack posts.
d. Ensure that the chassis is installed straight and level and secure the chassis using eight (two on each
flange) 12-24 x 3/4-inch or 10-32 x 3/4-inch screws through the elongated holes in the flanges and
into the threaded holes in the mounting posts.
NoteIf the rack mounting post holes are not threaded, you must obtain either 12-24 or 10-32 cage
nuts to secure the mounting screws. The cage nuts are not supplied as part of the four-post
rack mount kit.

Attaching System Ground
The system (NEBS) ground provides additional grounding for EMI shielding requirements and is
intended to satisfy the Telcordia Technologies NEBS requirements for supplemental bonding and
grounding connections.
To connect the system ground, you need the following tools and materials:
• Ground lug kit—Supplied as part of the Catalyst 4500-X series accessory kit. The ground lug kit
contains:
–
Ground lug—A two-hole standard 90-degree barrel lug. The lug supports up to 6 AWG wire.
–
Ground lug screws—Two M4 x 8 mm pan-head screws.
• Ground wire—The system ground wire should be sized according to local and national installation
requirements. We recommend that you use commercially available 6 AWG wire. The length of the
system ground wire depends on the proximity of the switch to proper grounding facilities. The
ground wire is not provided as part of the accessory kit.
• No. 1 Phillips screwdriver.
• Wire-stripping tool to remove the insulation from the ground wire.
• Crimping tool to crimp the system ground wire to the ground lug.
Attaching System Ground
To attach the system ground wire to the ground lug and attach the lug to the grounding pad, follow these
steps:
Step 1If you are using insulated wire, use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of
the covering from the end of the ground wire. If you are using bare wire, go to Step 2.
Step 2Insert the stripped end of the ground wire into the open end of the ground lug.
Step 3Crimp the ground wire in the barrel of the ground lug. Gently tug on the ground wire to verify that it is
securely attached to the ground lug.
Step 4Place the ground wire lug against the system ground pad located on the rear panel of the chassis (see
Figure 2), making sure that there is solid metal-to-metal contact.
Step 5Secure the ground lug to the chassis with the two M4 screws supplied in the accessory kit. (See
Figure 13.) Route the system ground wire to ensure that it does not interfere with other switch hardware
or rack equipment.
Step 6Prepare the other end of the ground wire and connect it to an appropriate earth ground point in your site
NoteDepending on your configuration, you might not need to install all of the cables described in the
following sections.

application, such as HyperTerminal or ProcommPlus, makes communication between the switch and
your PC or terminal possible.
Step 3Configure the baud rate and character format of the PC or terminal to match the console port
characteristics:
• 9600 baud
• 8 data bits
Installing the Interface Cables
• 1 stop bit
• No parity
• None (flow control)
Step 4The PC or terminal displays the bootloader sequence. Press Enter to display the setup prompt. Follow
the steps in the “Configuring the Setup Program” section on page 47.
Installing the Ethernet Management Port Cable
The Ethernet management port provides out-of-band management, which enables you to use the CLI
interface to manage the switch by its IP address. This port uses a 10/100/1000 Ethernet connection with
an RJ-45 interface. Figure 14 shows a typical Ethernet management connection between the switch and
a PC.
The typical connection to the Management Ethernet port uses an Ethernet cable with RJ-45 connectors
at each end. To attach a cable to the Ethernet management port, follow these steps:
Step 1Connect the RJ-45 plug at one end of the network cable to the target device port.
Step 2Connect the RJ-45 plug at the other end of the network cable to the Ethernet Management port on the
Catalyst 4500-X chassis.

The network interface ports on the Catalyst 4500-X switch front panel require that either an SFP or an
SFP+ transceiver be installed to operate. Not all SFP or SFP+ transceivers might be supported by the
Catalyst 4500-X switch. Additionally, there restrictions on when you can use the SFP-10G-ZR SFP+
transceiver on the Catalyst 4500-X series switch.
NoteSupport restrictions for the SFP-10G-ZR SFP+ transceiver on a Catalyst 4500-X switch include:
• For Catalyst 4500-X switch chassis operating with back-to-front airflow, the SFP-10G-ZR
transceiver is not supported on ports 1 through 32 (32 port chassis) or on ports 1 through 16 (16 port
chassis)
• For Catalyst 4500-X switch chassis operating with front-to-back airflow, the SFP-10G-ZR
transceiver is supported on ports 1 through 32 (32 port chassis) or on ports 1 through 16 (16 port
chassis).
• The SFP-10G-ZR transceiver is supported on ports 1 through 8 on the optional network uplink
module (part no. C4KX-NM-8SFP+) irrespective of the chassis airflow direction.
For an up-to-date list of which SFP transceivers are supported, see the Cisco Gigabit Ethernet Transceiver Modules Compatibility Matrix at this URL:
For an up-to-date list of which SFP+ transceivers are supported, refer to the Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix at this URL:
Installing the Ethernet Uplink Module Port Transceivers and Cables (Optional)
When installed in the Catalyst 4500-X switch chassis, the optional 8-port Ethernet uplink module
(C4KX-NM-8SFP+) requires either SFP (1000BASE-X) or SFP+ (10GBASE-X) transceiver modules to
operate. For an up-to-date list of which SFP transceivers are supported, see the Cisco Gigabit Ethernet Transceiver Modules Compatibility Matrix at this URL:

The Catalyst 4500-X series switch supports the following combinations of power supplies:
• One or two AC-input power supplies
• One or two DC-input power supplies
• One AC-input power supply and one DC-input power supply
NoteThe AC-input power supply is not supplied as part of the standard chassis configuration. Power supplies
must be ordered separately.
The Catalyst 4500-X switch chassis supports either one or two AC-input power supplies in bays located
at the back of the chassis. (See Figure 2.) Use the appropriate AC power cord to connect your chassis
AC-input power supply to source AC. See the Catalyst 4500-X AC-Input Power Supply Installation Note
for a list and descriptions of the AC power cords supported by the Catalyst 4500-X switch AC-input
power supply.
In chassis equipped with redundant power supplies, it is recommended that you connect the power
supplies to separate source AC circuits to prevent the chassis from shutting down in the event that one
source AC circuit fails.
OL-24795-01
NoteThe AC-input power supply does not have a power switch. Once the power cord is connected between
the AC-input power supply and source AC and source AC is on, the power supply immediately powers

Attaching the DC-Input Power Supply Power Cable
Attaching the DC-Input Power Supply Power Cable
The Catalyst 4500-X series switch supports either one or two DC-input power supplies in bays at the
back of the chassis. (See Figure 2.) Procedures for cabling source DC to the DC-input power supply are
contained in the Catalyst 4500-X DC-Input Power Supply Installation Note.
NoteThe DC-input power supply is not supplied as part of the standard chassis configuration. Power supplies
must be ordered separately.
NoteThe DC-input power supply does not have a power switch. Once the cabling is complete between the
power supply and source DC and the source DC breaker is turned on, the power supply immediately
powers up.
Monitoring the LEDs
The Catalyst 4500-X series switch has a complement of LEDs that provide the status of the chassis
components as the system powers up. As the chassis powers up, you can monitor the progress by
watching the LEDs located on the front panel of the chassis, the front panel of the fan tray (located at
the back of the chassis), and the front panel of the power supplies (located at the back of the chassis) as
follows:
• STATUS LED cycles from flashing green to amber to green
• Power supply LEDs (PS1/PS2) cycles from amber to green
• FAN LED cycles from amber to green
Once the chassis has completed the power up cycle (STATUS LED is green), you are ready to perform
a configuration of the chassis. See the Software Configuration Guide for detailed procedures on how to
configure your system.
