Rack-Mounting Guidelines
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.
Note This 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)).
- 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.

Temperature
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.
- 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.
Note The 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.
Airflow
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.
–
–
–
- Verify that the enclosed or partially enclosed rack allows an adequate flow of air through the switch chassis as follows:
–
–
Note The 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.
Humidity
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.
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:
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.
Note To 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.
Caution Category 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.
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.
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
Caution Installations that rely solely on system grounding using only an AC third-prong ground run a substantially greater risk of equipment problems and data corruption than those installations that use both the AC third-prong ground and a properly installed system (NEBS compliant) ground.
Table 6 lists some general grounding practice guidelines.
Note In 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 the product within its marked electrical ratings and product usage instructions.
- Install the product in compliance with local and national electrical codes.
- If any of the following conditions occur, contact the Cisco Technical Assistance Center:
–
–
–
–
–
- 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.
Note This system ground is also referred to as the network equipment building system (NEBS) ground.
After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:
Step 1
a.
b.
Step 2
Step 3
a.
Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.
b.
Caution For 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.
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:
20 A for AC systems, 30 A for DC systems Statement 1005
Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028
Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045
This section includes the following topics:
- Power Connection Guidelines for AC-Powered Systems
- Power Connection Guidelines for DC-Powered Systems
- Cabling Requirements
Power Connection Guidelines for AC-Powered Systems
This section provides some basic guidelines for connecting the AC power supplies to the site power source:
–
–
- 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).
- 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
Caution The 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:
Caution We 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:
Caution Category 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 Network Interface Port Cables
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.
Note Support 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:

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:

Attaching the AC-Input Power Supply Power Cord
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
Note The 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.
Note The 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 up.
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 .
Note The DC-input power supply is not supplied as part of the standard chassis configuration. Power supplies must be ordered separately.
Note The 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.
Entering the Initial Configuration Information
To set up the switch, you need to complete the setup program, which runs automatically after the switch is powered on. You must assign an IP address and other configuration information necessary for the switch to communicate with the local routers and the Internet. This information is also needed to use the device manager or Cisco Network Assistant to configure and manage the switch.
Configuring the Setup Program
To complete the setup program and an initial configuration for the switch, follow these steps:
Step 1
Step 2
On a command switch, the host name is limited to 28 characters and on a member switch it is limited to 31 characters. Do not use -n , where n is a number, as the last character in a hostname for any switch.
Step 3
The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows spaces, but ignores leading spaces. The secret password is encrypted, and the enable password is in plain text.
Step 4
Step 5
The password can be from 1 to 25 alphanumeric characters, is case sensitive, allows spaces, but ignores leading spaces.
Step 6
Step 7
Step 8
Step 9
If you enter N , the switch appears as a candidate switch in the Network Assistant GUI. You can configure the switch as a command switch later through the CLI, the device manager, or the Network Assistant application. To configure it later, enter no .
You have completed the initial configuration of the switch, and the switch displays its configuration. This is an example of the configuration output:
Step 10
Make your selection, and press Return .
After you complete the setup program, the switch can run the default configuration that you created. To change this configuration or to perform other management tasks, enter commands at the Switch> prompt or use Cisco Network Assistant.
