THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally
before we release them, and we strive to correct all vulnerabilities quickly. If you
think that you might have identified a vulnerability in a Cisco product, contact
PSIRT:

• Emergencies— [e-mail]

An emergency is either a condition in which a system is under active attack
or a condition for which a severe and urgent security vulnerability should be
reported. All other conditions are considered nonemergencies.

• Nonemergencies— [e-mail]

In an emergency, you can also reach PSIRT by telephone:

• 1 877 228-7302

• 1 408 525-6532

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to

encrypt any sensitive information that you send to Cisco. PSIRT can work from
encrypted information that is compatible with PGP versions 2.x through 8.x.

Preface

Never use a revoked or an expired encryption key. The correct public key to use
in your correspondence with PSIRT is the one linked in the Contact Summary
section of the Security Vulnerability Policy page at this URL:

solutions. If your issue is not resolved using the recommended resources, your
service request is assigned to a Cisco engineer. The TAC Service Request Tool is
located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the
Cisco TAC by telephone. (S1 or S2 service requests are those in which your
production network is down or severely degraded.) Cisco engineers are assigned
immediately to S1 and S2 service requests to help keep your business operations
running smoothly.

To open a service request by telephone, use one of the following numbers:

Preface

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has
established severity definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your
business operations. You and Cisco will commit all necessary resources around
the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or
significant aspects of your business operation are negatively affected by
inadequate performance of Cisco products. You and Cisco will commit full-time
resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most
business operations remain functional. You and Cisco will commit resources
during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product
capabilities, installation, or configuration. There is little or no effect on your
business operations.

Fan assembly

The Catalyst 4503 switch supports the Supervisor Engine II, II+, II+TS, II+10GE,
IV, V, and V-10GE. The supervisor engine has a nonblocking, full-duplex,
switching fabric that provides connections between the supervisor engine and the
switching modules. The Gigabit Ethernet ports can be configured with any
combination of copper 1000BASE-T, shortwave SX, LX/LH, and ZX interfaces,
or CWDM and DWDM GBICs. For a description of GBICs, refer to the Catalyst

4500 Series Module Installation Guide or the Catalyst 4500 Series Supervisor
Engines and Switching Modules Installation Note. Some supervisor engines use

SFP modules for Gigabit Ethernet connections, or X2 modules for 10-Gigabit
Ethernet connections. Refer to the installation note for your supervisor engine for
more details on these modules.

The Catalyst 4510R switch supports the Supervisor Engine V and V-10GE. The
supervisor engine has a nonblocking, full-duplex, switching fabric that provides
connections between the supervisor engine and the switching modules. The
Gigabit Ethernet ports can be configured with any combination of copper
1000BASE-T, shortwave SX, LX/LH, and ZX interfaces, or CWDM and DWDM
GBICs. For a description of GBICs, refer to the Catalyst 4500 Series Module

1-14

Catalyst 4500 Series Switches Installation Guide

78-14409-08

Chapter 1 Product Overview

Installation Guide or the Catalyst 4500 Series Supervisor Engines and Switching
Modules Installation Note. Some supervisor engines use SFP modules for Gigabit

Ethernet connections, or X2 modules for 10 Gigabit Ethernet connections. Refer
to the installation note for your supervisor engine for more details on these
modules.

Slot 1 is reserved for the supervisor engine only, which provides switching, local
and remote management, and switch-status monitoring. Slot 2 is reserved for a
redundant supervisor engine only. Slots 3 through 9 are available for switching
modules. When using a Supervisor Engine V, slot 10 is a flex-slot for use with the
2-port Gigabit Ethernet switching module (WS-X4302-GB) or the Access
Gateway Module (WS-X4604-GWY) only. When using a Supervisor Engine
V-10GE, any supported module may be used in slot 10.

Chapter 1 Product Overview

Gigabit Ethernet Uplink Ports

The Gigabit Ethernet uplink ports operate in full-duplex mode only. GBICs have
SC connectors to interface with multimode fiber (MMF) and single-mode fiber
(SMF) cable. For more information about GBICs, refer to the Catalyst 4500
Series Module Installation Guide.

When two Supervisor Engine Vs are present in a Catalyst 4507R and Catalyst
4510R, all four uplinks are active on both Primary (active) and Secondary
(standby) supervisor engines by default, or two uplinks will be active in a
nonredundant configuration. This limits access to slot 10 on the Catalyst 4510R
to ports 3 and 4 only. You can only use the 2-port Gigabit Ethernet switching
module (WS-X4302-GB) or the Access Gateway Module (WS-X4604-GWY) in
slot 10 (flex-slot), when a Supervisor Engine V is used.

10-Gigabit Ethernet Uplink Ports

The 10-Gigabit Ethernet uplink ports operate in full-duplex mode only, and are
only on the WS-X4516-10GE and WS-X4013+10GE. These ports use the
hot-swappable 10GBASE X2 optical transceivers. The X2s have SC connectors to
interface with multimode fiber (MMF) and single-mode fiber (SMF) cable.

Supervisor Engines

78-14409-08

On a Catalyst 4510R with a Supervisor Engine V-10GE, the user has the option to
use either four Gigabit Ethernet uplinks using SFPs or two 10-Gigabit Ethernet
uplinks using X2s. The user also has the option of using the Gigabit Ethernet and
10-Gigabit Ethernet uplinks simultaneously. With this option, the tenth slot can
only support the WS-X4302-GB switching module. On a Catalyst 4507R, the user
can use the Gigabit Ethernet uplinks and 10-Gigabit Ethernet uplinks
simultaneously.

When two Supervisor Engine V-10GEs are present in a Catalyst 4510R or Catalyst
4507R switch, or two Supervisor Engine II-Plus 10GEs are present in a Catalyst
4507R, one X2 uplink is active on both the primary (active) and secondary
(standby) supervisor engines by default, or two uplinks will be active in a
nonredundant configuration.

Supervisor Engines

SFP Ports

Gigabit Ethernet SFP ports operate in full-duplex mode only and are present on
the WS-X4013+TS, WS-X4516-10GE and WS-X4013+10GE supervisors, as
well as some switching modules. These ports use the 1000BASE-SX,
1000BASE-LX, Cisco Coarse Wave Division Multiplexing (CWDM ) SFPs,
1000BASE-T SFP, and 1000BASE-ZX SFP. SFP connectors vary with interface
type and may use multimode fiber (MMF), single-mode fiber (SMF) cable, or
copper Ethernet cables.

10/100BASE-T Port

The 10/100BASE-T port supports emergency image recovery. The
10/100BASE-T port supports image downloads from the ROMMON. You can use
this feature when the onboard Flash memory does not contain any IOS images,
usually after all images were accidentally deleted from onboard Flash.

Chapter 1 Product Overview

CONSOLE Port

Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance

RESET Button

Catalyst 4500 Series Switches Installation Guide

1-26

The CONSOLE port has an EIA/TIA-232 RJ-45 connector. The CONSOLE port
allows you to perform the following functions:

• Configure the switch from the CLI

• Monitor network statistics and errors

• Configure SNMP agent parameters

as a standard by the Electronic Industries Alliance (EIA) and Telecommunications
Industry Association (TIA).

The RESET button is used to restart the switch.

Chapter 1 Product Overview

Note Use a paper clip or other small, pointed object to press the Reset button.

CompactFlash Port

The CompactFlash port accepts a Type 1 CompactFlash card. You can use it for
file transfer tasks such as loading a new software image. The CompactFlash card
is optional, and can be obtained from third-party suppliers.

For more information, refer to Using the Compact Flash on the Catalyst 4000
Family Supervisor Engine III and IV at the following URL:

Fan Assembly

Fan Assembly

78-14409-08

Note For complete environmental specifications, including airflow requirements, see

Appendix A, “Specifications.”

The system fan assembly provides cooling air for the internal chassis components.
The fan assembly is a tray of fans that you can insert and remove from the chassis
while the system is on line. The Catalyst 4503 fan assembly has two fans, the
Catalyst 4506 fan assembly has four fans, the Catalyst 4507R fan assembly has
six fans, and the Catalyst 4510R fan assembly has eight fans. The fans draw in
fresh air from one side and exhaust air on the other side. Catalyst 4503 airflow is
shown in Figure 1-13. Catalyst 4506 airflow is shown in Figure 1-14.
Catalyst 4507R airflow is shown in Figure 1-15. Catalyst 4510R airflow is shown
in Figure 1-16.

Caution You must install module filler plates on unused switching module slots to ensure

proper airflow.

Chapter 1 Product Overview

Power Supplies

Note For detailed specifications on all Catalyst 4500 series power supplies, refer to the

“Catalyst 4500 Series Power Supplies” section on page A-7.

A Catalyst 4500 series switch can use a 1000 W, 1300 W, 1400 W, 2800 W (see

Figure 1-17), or 4200 W (with two inputs, see Figure 1-18) AC-input power

supply , a 1400 W DC-input power supply with integrated PEM (see Figure 1-19),
or a 1400 W DC multiple-input power supply (see Figure 1-20).

The AC-input power supply has a power cord that connects each power supply to
the site power source. The DC-input power supply is equipped with a input
terminal block that is directly connected to the site power wiring.

Each power supply has an ON/OFF switch that supplies power to the switch. For
information on removing and replacing power supplies, see the “Removing and

Replacing the Power Supply” section on page 4-2.

The 1400 W DC input power supply (either single or triple-input) may be used
with the Catalyst 4500 Series AC Power Shelf. Documentation for the Catalyst
4500 Series AC Power Shelf is at http://www.cisco.com/univercd/cc/td/doc

/product/lan/cat4000/inst_nts/78_15068.htm

Catalyst 4500 series switches support one power supply and an optional
redundant power supply. Each AC power supply has an individual power cord and
status LEDs. Systems with redundant power supplies will share the load, with
each unit providing approximately one-half of the total load. For information
about configuring your switch for redundant and combined modes, refer to the
software configuration guide for your switch.

The Catalyst 4510R requires at least 1400 W of input power. (The 1000 W AC and
1300 W AC power supplies for the Catalyst 4500 series will fit and function in a
Catalyst 4510R; however, power management may be required in high density
configurations.) Cisco recommends the use of the 1400 W DC, 1400 W AC, and
2800 W AC power supplies for the Catalyst 4510R.

When power is removed from one power supply on a Catalyst 4500 series switch
that has two power supplies, the redundant power feature causes the second power
supply to produce full power.

Chapter 1 Product Overview

Power Supply Fan

Each power supply has a built-in fan. Air enters the front of the power supply
(power-input end) and exits through the back. An air dam keeps the airflow
separate from the rest of the chassis, which is cooled by the system fan assembly.

Load-Sharing Feature

When you install and turn on a second power supply on a Catalyst 4500 series
switch, it provides approximately one-half of the required power to the system. If
one power supply fails, the other power supply immediately assumes full power
to maintain uninterrupted system operation.

Note Load sharing works only when both power supplies in the chassis are the same

type.

When you install a redundant power supply, load sharing and fault tolerance are
enabled automatically; no additional software configuration is required.

Power Supplies

Environmental Monitoring Feature

With the environmental monitoring and reporting feature, you can keep your
system running by resolving adverse environmental conditions before loss of
operation.

The power supply monitors its own internal temperature and voltages. In the event
of excessive internal temperature, the power supply shuts down to prevent
damage. When the power supply returns to a safe operating temperature, it
restarts. If the power supply output voltage is not within the specified range, the
LED labeled OUTPUT FAIL will light. An instance of substantial output
overvoltage can shut down the power supply.

An instance of substantial input overvoltage (greater than –75 V DC continuous)
can damage the power supply input circuitry and can cause it to shut down
permanently.

Chapter 1 Product Overview

Power Supplies

For a 1400 W DC power supply, the main power switch has an input range of
–40.5 to –72 V DC, while the –48 V PoE operates over a range of –40.5 to
–56 V DC. The PoE either fails to start or shuts down if exposed to greater than
–56 V DC input. PoE recovers after you recycle input power within the proper
voltage range. If the PoE shuts down due to input overvoltage (greater than –56
V DC), the main converter section does not shut down.

The supervisor engine monitors the status of each power supply and provides a
status report through the switch software. For more details on how the supervisor
engine monitors the power supplies, refer to the “Environmental Monitoring and
Power Management” chapter of the Catalyst 4500 Series Switch Cisco IOS
Software Configuration Guide.

1400 W DC Triple-input Power Supply Operational Modes

The C4500 1400 W DC Triple Input SP Power Supply (data only) allows added
redundancy by providing terminals for two DC inputs rated at 15 A and one rated
at 12.5 A per power supply.

This power supply has five operational modes depending on the inputs receiving
power. When all three inputs are active, at input voltages greater than –44.0 V DC,
the power supply delivers 1400 W maximum total output. Tabl e 1 -8 provides
output information for these modes, given a single supply.

a dashed line) to PoE-enabled switching modules, which is then available to the
powered device connected to the switching module.

Note The Supervisor Engine II-Plus TS has internal DC-to-DC converters that use the

12 V circuit to provide PoE to powered devices connected to the Supervisor
engine only. If your system has a Supervisor Engine II-Plus TS in slot 1, you still
need a PoE-enabled power supply to provide PoE to the other slots.

All Catalyst 4500 series switches support dual power supplies, configurable as
combined mode or redundant mode. In combined mode, the switch has available
the combined rated wattage of both power supplies, less some expected efficiency
loss. In redundant mode, one power supply provides power to the system and the
other supply is on standby should there be a failure in either the power supply or
the input voltage source it is connected to.

Power over Ethernet

System Architecture

78-14409-08

The Cisco Catalyst 4500 Series switches support the Cisco pre-standard and

802.3af standard for PoE on 10/100 or 10/100/1000 ports, enabling customers to
support telephones, wireless base stations, video cameras, and other appliances.
PoE makes it possible to place devices in unique locations without having to
provide new outlets and costly electrical circuits. PoE also enables businesses to
isolate critical devices on a single power system so that the entire system can be
supported by uninterruptable power supply (UPS) backup.

All new Cisco Catalyst PoE line cards can support 15.4 W of power per port
simultaneously. Not only do the cards support the IEEE standard, including the
optional power classifications, but the Cisco pre-standard power implementation
is also supported to help ensure backward compatibility with existing Cisco
powered devices. The cards are compatible with any chassis and supervisor
engine. Most importantly, the Catalyst 4500 series switch has the power supplies
and accessories to support 15.4 W per port on every port simultaneously in any
fully loaded chassis. (This requires an external power shelf or a 4200 W dual-input
power supply.)

PoE Over-subscription

Chapter 1 Product Overview

With the advent of powered devices requiring as much as 15.4 W and the different
combinations of power supplies and chassis port densities, it becomes quite
possible to over-subscribe the PoE capacity of the power supplies. This temporary
over-subscription typically occurs when a power supply configured in combined
mode fails or when the user has not kept track of the powered devices and plugs
in one too many. The best practice is to design a PoE system in which all devices
receive the power needed at all times. When a power supply is
over-subscribed—more power is being drawn from it than it can supply—the
power supply shuts down. There are several ways to predictably manage a
temporary PoE over-subscription:

1. Configure unused ports to never receive PoE. This prevents a user from

inadvertently plugging a powered device into a port and causing problems for
other powered devices.

2. Configure ports to be in static mode. This is for ports that have highest

priority, such as phones for executives or wireless access points. If ports need
to be disabled because of a power shortage, auto ports are disabled before
static ports.

PoE Line Cards

1-42

3. Configure the maximum wattage on ports to be less than the default, based on

the maximum power consumption of the powered device. This disallows
devices demanding unexpected amounts of power and also stretches the finite
resources of the power supplies. For example, the default port wattage is

15.4 W. By configuring a maximum of 7 W, twice as many PoE powered
devices can be supported with the same power supply.

The Cisco Catalyst 4500 series offers line cards, power supplies, and accessories
required to deploy and operate a standards-based PoE internetwork. PoE provides
–48 V DC power over standard Category 5 unshielded twisted-pair (UTP) cable
up to 100 meters when an IEEE 802.3af-compliant or Cisco pre-standard powered
device is attached to the PoE line card port. Instead of requiring wall power,
attached devices such as IP phones, wireless base stations, video cameras, and
other IEEE-compliant appliances can use power provided by the PoE line cards.
This capability gives network administrators centralized control over power and
eliminates the need to install outlets in ceilings and other out-of-the-way places
where a powered device may be installed.

Catalyst 4500 Series Switches Installation Guide

78-14409-08

Chapter 1 Product Overview

Although references to “PoE,” “inline-power,” and “voice” power supplies and
line cards are synonymous, there are only two versions: Cisco prestandard and
IEEE 802.3af compliant. Every Cisco Catalyst 4500 series chassis and PoE power
supply supports the IEEE 802.3af standard and the Cisco prestandard power
implementation ensuring backward compatibility with existing Cisco powered
devices. All IEEE 802.3af-compliant line cards can distinguish an IEEE or Cisco
prestandard powered device from an unpowered network interface card (NIC),
ensuring that power is applied only when an appropriate device is connected.

All PoE line cards can distinguish an IEEE or Cisco prestandard powered device
from an unpowered network interface card (NIC) to ensure power is applied only
when an appropriate device is connected. With a Cisco PoE network,
administrators can depend on a robust network that is safe to deploy and simple
to maintain.

Deploying PoE on the Cisco Catalyst 4500 Series

When the switch is properly configured, implementing PoE is easy when it is used
with a Cisco powered device that supports Cisco Discovery Protocol. All PoE line
cards automatically detect an attached powered device the moment it is installed.
Also, the switch returns unused port power to the system power budget for use by
other devices because it supports the IEEE802.3af optional power classifications.

System Architecture

78-14409-08

The Cisco Catalyst 4500 series offers internal power supplies and external power
devices for multiple deployment scenarios. These scenarios include small and
large deployments in AC or DC environments for data-only configurations, and
scalability of up to 15.4 W per port for PoE configurations.

The switches share a common power supply form factor. Each Cisco Catalyst
4500 Series chassis is designed for 1 + 1 power protection while meeting the
needs of PoE demands. In addition to power resiliency, the Cisco Catalyst 4500
Series includes 1 + 1 supervisor-engine redundancy (Cisco Catalyst 4507R and
Catalyst 4510R only) and software-based fault tolerance. Integrated resiliency in
both hardware and software minimizes network downtime, helping ensure
workforce productivity, portability, and customer success.

All available Cisco Catalyst 4500 Series power supplies can be used for data-only
deployments, which typically require just a few hundred watts. For deployments
that dictate support for PoE power, Cisco offers several options.

The Cisco Catalyst 4500 Series offers several internal supplies: 1000 W AC (data
only), 1400 W AC (data only), 1300 W (data and PoE), 1400 W DC (data and
PoE), 2800 W (data and PoE), and 4200 W AC (data and PoE). When more than

Catalyst 4500 Series Switches Installation Guide

System Architecture

4200 W of redundant data and PoE are required for a Cisco Catalyst 4500 Series
chassis in an AC-powered environment, Cisco offers an external AC power shelf
that houses two 2500 WAC power supplies. When two power shelves are
combined, they can produce 7500 W—the remaining 2500 W supply can be used
for N + 1 protection.

The Cisco Catalyst 4500 Series has two DC power options; one is optimized for
data-only deployments in service provider central offices (part number
PWR-C45-1400DC), and the other is used for high-power PoE deployments (part
number PWR-C45-1400DC-P).

Cisco Catalyst 4500 Series External AC Power Shelf and
1400 W DC Power Supply with Integrated Power Entry Module

The external AC power shelf must be used in conjunction with the 1400 W DC
power supply. In addition to providing power for the chassis, fans, and non-PoE
line cards, the 1400 W DC power supply contains a power entry module (PEM).
The PEM is used to pass additional power to the chassis backplane, power
demanded by the PoE line cards. The chassis power trace used for PoE is
independent from the one used by the supervisor engine(s), fan tray, and
backplane components. The 1400 W DC power supply can accept up to
7500 W DC for data and PoE applications. Up to 1400 W can be dedicated for
data (supervisor engine, fan tray, etc.), while the remaining power is passed
through via the PEM and is used for PoE.

Chapter 1 Product Overview

When only one external AC power shelf is used (with two 2500 W AC power
supplies), it provides the 1400 W DC power supply with 5000 W of DC power in
total. When two AC power shelves are strapped together, the switch can provide
up to 7500 W of DC power (3 + 1 redundant).

Cisco Catalyst 4500 Series Service Provider DC Power Supply

The triple-input 1400 W DC power supply is optimized for service provider or
central-office deployments. By providing multiple inputs, the service provider DC
power supply enables central-office technicians to customize the output power to
meet their application needs. Many central-office deployments require only a
fraction of the 1400 W available in the service provider power supply. Low current
inputs mean technicians can connect the supply to smaller fuses and breakers. The
service provider power supply makes it possible to deploy a Cisco Catalyst 4503

Each system component has an EEPROM that identifies it to the supervisor
engine over a serial connection on the backplane, which also passes along
information like temperature, fan speed, power draw per slot and port, and port
activity. LED status information is also sent to the supervisor engine, which
makes it available to an administrator through a terminal connection or
management software.

All Catalyst 4500 series switches support:

• Hardware-based multicast-Protocol Independent Multicast (PIM).

• Internet Group Management Protocol (IGMP).

• Cisco Group Management Protocol support standards-based and Cisco

technology-enhanced efficient multimedia networking.

• Simple Network Management Protocol (SNMP).

• CiscoWorks, which can manage critical network characteristics such as

availability, responsiveness, resilience, and security.

• Cisco NetFlow Services. The Cisco NetFlow Services Card for the Supervisor

Engine IV and V support statistics capture in hardware for flow-based and
VLAN-based statistics monitoring. This data can be exported, collected, and
analyzed for virus detection and mitigation, network-traffic accounting,
usage-based network billing, network planning, network monitoring, and
data-mining capabilities. Cisco NetFlow Services is integral to the Supervisor
Engine V-10GE.

Frames flow into the switch through interfaces on the switching modules. Each
switching module connects to a mux/buffer on the backplane that supports a
connection of up to 6 Gbps up (Tx) to the supervisor engine and 6 Gbps from (Rx)
the supervisor engine. When a frame reaches the supervisor engine, it is examined
and either sent out of an interface in one of the other slots, or out of the uplink on
the supervisor engine.

Over-subscription

78-14409-08

Switching modules that have 24 or 48 Gigabit Ethernet (1000BASE-T) ports
over-subscribe on a Catalyst 4500 switch by grouping the ports with an additional
mux/buffer on the switching module, which creates a single, nonblocking,
full-duplex Gigabit Ethernet connection to the internal switch fabric. For each
group of ports, frames received are buffered and sent to the common Gigabit

System Architecture

Supervisor Redundancy

Chapter 1 Product Overview

Ethernet link to the internal switch fabric. If the amount of data received for a port
begins to exceed buffer capacity, flow control sends pause frames to the remote
port to temporarily stop traffic and prevent frame loss.

Each port in the group shares the bandwidth of a Gigabit Ethernet link. However,
each port operates independently so that flow control, or configuration of one
port, does not block or degrade the performance of another port in that group.
Switching modules that have up to six 1000BASE-T ports do not use
over-subscription.

The amount of over-subscription can be controlled by varying the number of ports
used at 1000 Mbps. All ports can use Cisco Gigabit EtherChannel technology or
IEEE 802.3ad for high-speed interconnection applications. All over-subscribed
ports use the standard IEEE 802.1x flow control (PAUSE frame) mechanism to
control Gigabit Ethernet host traffic.

The Cisco Catalyst 4507R and Catalyst 4510R switches support 1+1
supervisor-engine redundancy for integrated resiliency. Redundant supervisor
engines help minimize network downtime. With the support of stateful switchover
(SSO), the secondary supervisor engine serves as a backup to immediately take
over after a primary supervisor failure. During the switchover, Layer 2 links are
maintained transparently without the need to renegotiate sessions. As a result,
business-critical applications such as Voice-over-IP (VoIP) calls are not dropped.
The Nonstop Forwarding (NSF) Aware feature in Cisco IOS software is also
supported, providing the ability to interface with NSF-capable devices and to
continue forwarding packets as routing information is updated upon a
supervisor-engine switchover.

Chapter 2 Preparing for Installation

If you will be using your switch as a PoE source, the following warning applies:

Warning

Voltages that present a shock hazard can exist on inline power circuits if
interconnections are made by using uninsulated exposed metal contacts,
conductors, or terminals. Avoid using such interconnection methods unless the
exposed metal parts are in a restricted access location and users and service
people who are authorized to access the 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.

This chapter describes how to prepare your site for the installation of the switch.
The information is presented in these sections:

• Site Power Requirements and Heat Dissipation, page 2-4

• Power Connection Guidelines for AC-Powered Systems, page 2-5

• Site-Planning Checklist, page 2-16

Note See the Site-Planning Checklist at the end of this chapter to help ensure that you

complete all site-planning activities before you install the switch.

Electrostatic Discharge

Statement 1072

2-2

Electrostatic discharge is common on Category 5E and Category 6 cabling
systems.

Category 5E and Category 6 cables have higher capacitance than Category 5
cables. As a result, Category 5E and Category 6 cables can store higher voltages
than Category 5 cables and are more prone to damaging networking equipment if
a differential discharge event occur.

Unshielded twisted-pair cables can store high voltages. When these charged
cables are connected to networking equipment, energy is discharged into the
networking equipment; this is known as electrostatic discharge (ESD).
Networking equipment is commonly designed and tested to withstand common
mode ESD events of up to 2000 V. The design for the common mode event is
based on the expectation that the discharge is delivered to all pins of a port at once.

Catalyst 4500 Series Switches Installation Guide

78-14409-08

Chapter 2 Preparing for Installation

Sometimes, voltage is discharged to some of the pins of the connector and not
others, or to some pins on the connector before others. This is known as a
differential discharge event, which can damage the networking equipment being
connected.

You can take the following measures to prevent ESD cable damage:

• Ground the cable before connecting the networking equipment. You can

create a grounding cable using an RJ-45 patch cable by doing the following:

–

–

–

• Briefly connect all cables to the grounded cable before connecting to

networking equipment.

• Leave cables from the networking equipment in the distribution closet

connected to ports at user desktops. After you make connections on either
side of the cable to networking equipment, the cable will not build up charge.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or
components are improperly handled, results in complete or intermittent failures.
Port adapters and processor 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, use a preventive antistatic strap during
handling.

Following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin

contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use any available ejector levers or captive

installation screws toproperly seat the bus connectors in the backplane or
midplane. These devices prevent accidentalremoval, provide proper
grounding for the system, and help to ensure that bus connectors areproperly
seated.

Catalyst 4500 Series Switches Installation Guide

78-14409-08

Site Power Requirements and Heat Dissipation

• When removing a component, use any available ejector levers or captive

installation screws to release the bus connectors from the backplane or
midplane.

• Handle carriers by available handles or edges only; avoid touching the printed

circuit boards or connectors.

• Place a removed component board-side-up on an antistatic surface or in a

static shielding container. If you plan to return the component to the factory,
immediately place it in a static shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap

only protects components from ESD voltages on the body; ESD voltages on
clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The

measurement should be between 1 and 10 megohm (Mohm).

Site Power Requirements and Heat Dissipation

This section provides module power requirements and heat dissipation
specifications for the Catalyst 4500 series switches. You should verify site power
before you install the switch.

For more information about power management and planning, refer to the
“Environmental Monitoring and Power Management” chapter in the Catalyst
4500 Series Switch Cisco IOS Software Configuration Guide version appropriate
for your software.

Knowing the power requirements is useful for planning the power distribution
system needed to support the switches. You should consider the heat dissipation
specifications when estimating the air-conditioning requirements for an
installation. For all Catalyst 4500 series switches, supervisor engines, and

Power Connection Guidelines for AC-Powered
Systems

This section provides guidelines for connecting the Catalyst 4500 series switch
AC power supplies to the site power source. Basic guidelines include the
following:

• Make sure each chassis power supply has its own dedicated branch circuit.

• Size the circuits according to local and national codes.

• If you are using a 200/240 VAC power source in North America, use a

two-pole circuit breaker to protect the circuit.

• Place the source AC outlet within 6 feet (1.8 meters) of the system and make

sure it is easily accessible.

• Make sure the AC power receptacles used to plug in the chassis are the

grounding type. The grounding conductors that connect to the receptacles
should connect to protective earth ground at the service equipment.

Four types of AC-input power supplies are available:

Power Connection Guidelines for DC-Powered Systems

Power Connection Guidelines for DC-Powered
Systems

This section provides the basic guidelines for connecting the Catalyst 4500 series
switch DC-input power supplies to the site power source or AC power shelf:

• All power connection wiring should conform to local and national codes.

• DC (–) and DC return (+) terminals are evaluated for use with 1/0 AWG wire

(1400W DC supply only).

• The ground terminal is evaluated for use with 6 AWG wire (10 AWG for the

multi-input power supply).

• DC (–) and DC return (+) wire lugs shall not exceed 0.83 inches in width

(0.378 inches for the multi-input power supply).

• 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 earth ground cable, one source DC (–), and one source
DC return (+). The length of the cables depends on your switch location.
These cables are not available from Cisco Systems. They are available from
any commercial cable vendor.

2-12

• The color coding of the source DC power cable leads depends on the color

coding of the site DC power source. Typically, green or green and yellow
indicate that the cable is a ground cable. 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.

Chapter 2 Preparing for Installation

Calculating DC Input Current

Complete power usage tables are in the Catalyst 4500 Series Module Installation
Guide. To calculate the DC input current needed for data and inline power

applications, use the following steps (the example shows the DC input current
requirement in a Catalyst 4503 with a Supervisor Engine II and two
WS-X4306-GB modules, and assumes a DC input voltage of -48 VDC):

Step 1 Add the power requirement for each component in your system.

• Catalyst 4503 uses 54 W

• Supervisor Engine II uses 147 W

• WS-X4306-GB uses 2 X 47 = 94 W

• Total DC input power = 295 W

Step 2 After the entries for all components have been added together, divide that number

by the DC input voltage to determine the DC input current.

• Input current = 295 W/48 VDC = 6.14 A for data only.

Power Connection Guidelines for DC-Powered Systems

78-14409-08

Step 3 to Step 5 are for applications requiring inline power. If your configuration
does not include inline power devices, the DC input current is the result of Step 2.

Step 3 If you want to add an inline-capable module (WS-X4148-RJ45V) with 10 inline

devices (such as IP Phones) to your system, calculate the DC output power sent
to inline devices.

• 10 X 6.3 W = 63 W for inline devices.

6.3 Watts is correct for a Cisco IP phone. Wattage consumption will depend on the
inline device used.

Step 4 Find the DC input power using the DC output power.

• 63/.96 (efficiency) = 65 W of DC input power.

Step 5 Divide the DC input power by the DC voltage input of –48 V to find the DC input

current used by inline devices.

• 65/48 = 1.4 Amps for inline devices.

Step 6 Add the DC input current used by data and the DC input current used by inline

Ventilation

Chapter 2 Preparing for Installation

devices to find the total DC input current.

• Total DC input current = 6.14 + 1.4 = 7.54 A.

Planning a proper location for the switch and the layout of your equipment rack
or wiring closet is essential for successful system operation. You should install the
switch in an enclosed, secure area, ensuring that only qualified personnel have
access to the switch and control of the environment. Equipment placed too close
together or inadequately ventilated can cause system overtemperature conditions.
In addition, poor equipment placement can make chassis panels inaccessible and
difficult to maintain.

The switch operates as a standalone system mounted in a rack in a secure wiring
closet. It requires a dry, clean, well-ventilated, and air-conditioned environment.
To ensure normal operation, maintain ambient airflow. If the airflow is blocked or
restricted, or if the intake air is too warm, an overtemperature condition can occur.
The switch environmental monitor can then shut down the system to protect the
system components.

2-14

To ensure normal operation and avoid unnecessary maintenance, plan your site
configuration and prepare your site before installation. After installation, make
sure the site maintains an ambient temperature of 0 to 40ºC (32 to 104ºF). It is
essential to keep the area around the chassis as free from dust and foreign
conductive material (such as metal flakes from nearby construction activity) as is
possible.

Multiple switches can be rack-mounted with little or no clearance above and
below the chassis. However, when mounting a switch in a rack with other
equipment, or when placing it on the floor near other equipment, ensure that the
exhaust from other equipment does not blow into the intake vent of the chassis.

Cooling air is drawn in through the right side of the chassis. Keep the right side
clear of obstructions, including dust and foreign conductive material, and away
from the exhaust ports of other equipment.

Catalyst 4500 Series Switches Installation Guide

78-14409-08

Chapter 2 Preparing for Installation

Appendix A, “Specifications,” lists the operating and nonoperating

environmental site requirements for the switches. To maintain normal operation
and ensure high system availability, maintain an ambient temperature and clean
power at your site. The environmental ranges listed in Appendix A,

“Specifications,” are those within which the switch will continue to operate;

however, a measurement that approaches 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.

Calculating System Heat Dissipation

To calculate the expected heat dissipation from a switch, add the total amount of
power drawn from power supply by the system's configuration, then divide the
total amount of power by the efficiency of the power supply. Multiply the result
by 3.415 to get the system heat dissipation in BTUs/hr.

First example (System without any powered devices):

Total heat dissipated by system = (267/.75) * 3.415 = 1215 BTUs/hr

Note All Catalyst 4000/4500 power supplies have different efficiencies, An average

efficiency figure of 75% was chosen.

Site-Planning Checklist

1 - IEEE class 3 device 17.3 W

total output power 284 W

Total heat dissipated by system = (284/.75) * 3.415 = 1293 BTUs/hr

Note Although a class 3 device needs 15.4 W to power up, 17.3 W need to be generated

from the backplane in order to have 15.4 W at the switch port. 17.3 W comes from
the WS-X4248-RJ45V DC-DC converter’s efficiency (89%).

Checking the Shipping Container Contents

Note For information on installing the supervisor engine and switching modules and

verifying switch operation, refer to the Catalyst 4500 Series Module Installation
Guide. For information on configuring the switching modules, refer to the

software configuration guide for your switch and software release.

Checking the Shipping Container Contents

Note Do not discard the shipping cartons and poly bag when you unpack the switch.

Flatten and store them. You will need the containers if you need to move or ship
the switch in the future. Repacking instructions are provided in Appendix B,

“Repacking a Switch.”

Follow these steps to check the contents of the shipping cartons:

3-2

Step 1 Check the contents of the accessories box against the Accessories Box

Components Checklist and the packing slip that were included with your switch.
Verify that you received all listed equipment, including the following:

• Switch hardware documentation and software documentation (if ordered)

• Optional equipment that you ordered, such as network interface cables,

transceivers, or special connectors

Step 2 Check the switching modules in each slot. Ensure that the configuration matches

the packing list and that all the specified interfaces are included.

Chapter 3 Installing the Switch in a Rack

Rack-Mounting the Switch

A standard rack-mount kit is included for mounting the switch in a standard
19-inch (48.3 cm) equipment rack with two unobstructed outer posts, with a
nominal depth (between the front and rear mounting posts) of 19.25 inches
(48.9 cm) and a maximum depth of 32 inches (81.3 cm). This kit is not suitable
for racks with obstructions (such as a power strip) that could impair access to the
field-replaceable units (FRUs) of the switch.

Alternatively, you can obtain a 23-inch rack-mount kit.

Required Installation Tools

You will need the following tools and equipment to install the chassis in a rack:

• Number 1 and number 2 Phillips screwdrivers to tighten the captive

installation screws on most systems

• 3/16-inch flat-blade screwdriver for the captive installation screws on the

supervisor engine and switching modules on some systems

Rack-Mounting the Switch

78-14409-08

• Antistatic mat or antistatic foam in case you need to remove switching

modules to troubleshoot the installation

• Rack-mount kit

• Tape measure

• Level

• Your own electrostatic discharge (ESD) grounding strap or the disposable

ESD strap included with the system

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you
must take special precautions to ensure that the system remains stable. The
following guidelines are provided to ensure your safety:

• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

• When mounting this unit in a partially filled rack, load the rack from the bottom to
the top with the heaviest component at the bottom of the rack.

• If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.

Follow these steps to install a Catalyst 4500 series switch in a rack:

Step 1 Prepare for installation as follows:

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 depth must be at least 19.25 inches (48.9 cm) but not greater than
32 inches (81.3 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.)

d. Open the rack-mount kit and check the component checklist in Ta ble 3 - 1 to

verify that all parts are included.

Quantity Part Description

2L brackets

6 M4 Phillips pan-head screws

6 12-24 x 3/4-inch Phillips binder-head screws

Note Some equipment racks provide a power strip along the length of one of

the rear posts. If your rack has this feature, consider the position of the
strip when planning fastener points. Before installing the L brackets on
the chassis, determine whether to install the chassis from the front or the
rear of the rack.

Step 2 Install the L brackets, which connect the chassis to the rack, as follows:

a. Remove the screws from the front of the switch side-cover panels.
b. Attach the left and right L brackets using the six M4 Phillips pan-head screws

(three screws per side) provided in the rack-mount kit.
