•Catalyst 4510R-E Switch Features, page 1-13
Power Redundancy
All Catalyst 4500-E switches offer 1+1 power redundancy, so that in the event of a power interruption
the switch can still operate using power from another circuit. The power supplies can also run in a
combined mode so that chassis can have power from both supplies at once. You will need to use the
power redundancy-mode command to configure combined mode. Redundant mode is the default.
Catalyst 4500-E switches support power supply redundancy only between power supplies of equal
wattage and type. A mix of power supplies is not supported. The second power supply recognized is
placed into err-disable mode.
A more detailed discussion of power redundancy is in the Environmental Monitoring and Power
Management chapter of the software configuration guide. Refer to the appropriate guide for your
software release.
Catalyst 4503-E Switch Features
The Catalyst 4503-E switch (see Figure 1-1) is a three-slot switch designed for high-performance

“Specifications.”
Supervisor Engine Redundancy
The Catalyst 4507R-E and Catalyst 4510R-E switches support supervisor engine redundancy.
Redundancy allows a second supervisor engine to take over if the active supervisor engine fails.
With supervisor engine redundancy enabled, if the active supervisor engine fails or if a manual
switchover is performed, the redundant supervisor engine becomes the active supervisor engine. The
redundant supervisor engine is automatically initialized with the startup configuration of the active
supervisor engine. Depending on the configuration this shortens the switchover time from 30 seconds or
longer in Route Processor Redundancy (RPR) mode, to less than a second in Stateful Switch Over (SSO)
mode.
In addition to the reduced switchover time, supervisor engine redundancy supports these:
•Online insertion and removal (OIR) of the redundant supervisor engine
Supervisor engine redundancy allows OIR of the redundant supervisor engine for maintenance.
When the redundant supervisor engine is inserted, the active supervisor engine detects it. The
redundant supervisor engine boots into a partially initialized state in RPR mode and a fully
initialized state in SSO mode.
•Software upgrade
Chapter 1 Product Overview
Load the new image on the redundant supervisor engine and conduct a switchover. This minimizes
downtime during software changes on the supervisor engine.
When power is first applied to a switch, the supervisor engine that boots first becomes the active
supervisor engine and remains active until a switchover occurs.
Redundancy requires that both supervisor engines in the chassis are of the same supervisor engine
model, and that they use the same Cisco IOS software image.
For more detail about redundancy, refer to the Configuring Supervisor Engine Redundancy Using RPR and SSO chapter of the software configuration guide for your software release.
The Catalyst 4507R-E switch supports the Supervisor Engine II+, Supervisor Engine IV, Supervisor
Engine V, Supervisor Engine V-10GE, and Supervisor Engine 6-E. The supervisor engine has two
Gigabit Ethernet ports and a nonblocking, full-duplex, switching fabric that provides connections
between the supervisor engine and the switching modules. 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 3 is reserved for the supervisor engine only, which provides switching, local and remote
management, and switch-status monitoring. Slot 4 is reserved for a redundant supervisor engine only.

Chapter 1 Product Overview
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, WS-X4013+10GE, and WS-45-Sup6-E. 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.
On a Catalyst 4510R-E with a Supervisor Engine V-10GE, the user can 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-E, 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-E or Catalyst 4507R-E switch,
or two Supervisor Engine II-Plus 10GEs are present in a Catalyst 4507R-E, one X2 uplink is active on

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.
WS-X45-Sup6-E supervisors can use Cisco TwinGig converters to support two SFPs per X2 uplink port,
for a maximum of 4 SFP ports per supervisor. SFP connectors vary with interface type and may use
multimode fiber (MMF), single-mode fiber (SMF) cable, or copper Ethernet cables. SFPs use LC type
fiber connectors and RJ-45 copper connectors.
10/100BASE-T Management Port
The 10/100BASE-T Management 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.

A Catalyst 4500 E-series switch can use a 1000 W, 1300 W, 1400 W, 2800 W (see Figure 1-13), or
4200 W (with two inputs, see Figure 1-14) AC-input power supply, a 1400 W DC-input power supply
with integrated PEM (see Figure 1-15), or a 1400 W DC multiple-input power supply (see Figure 1-16).
The power supplies are hot-swappable. If you have power supplies of different types installed in the two
bays, only one will be active and some power features will not be available. The power supply in the left
bay is PS1, the one in the right bay is PS2.
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
NoteThe 1400 W DC triple-input power supply is not compatible with other power supplies used on these
products, and can only be used with similar supplies. In redundant mode, the two power supplies must
have identical inputs.
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
Catalyst 4500 E-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-E requires at least 1400 W of input power. (The 1000 W AC and 1300 W AC power
supplies will fit and function in a Catalyst 4510R-E; however, power management may be required in high
density configurations.) Cisco recommends the use of the 1400
power supplies for the Catalyst
4510R-E.

the system fan assembly.
Load-Sharing Feature
When you install and turn on a second power supply on a Catalyst 4500 E-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.
NoteLoad 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.
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 over-voltage (greater than –75 V DC continuous) can damage the power
supply input circuitry and can cause it to shut down permanently.
For a 1400 W DC power supply, the main power switch has an input range of –40.5 to –72 V DC, while

Power enters the switch through the power supplies. Several types of power supplies are available,
depending on the power needs for your system and the power type available on your site. All power
supplies provide a 3.3 V circuit (shown as a dash-dot line) to the components on the backplane and a
12
V circuit (shown as a solid line) that is carried over the backplane to the fans, supervisor engine, and
switching modules. Power supplies that support PoE (1300 W AC, 2800 W AC, 4200 W AC or 1400 W
DC) also provide a –48 V circuit (shown as a dashed line) to PoE-enabled switching modules, which is
then available to the powered device connected to the switching module.
NoteThe 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 E-series switches support dual power supplies, configurable for 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
The Cisco Catalyst 4500 E-series switches support the 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 switching modules can support 15.4 W of power per port simultaneously.
Not only do the modules 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 modules are compatible with any chassis and supervisor engine.
Most importantly, the Catalyst 4500 E-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.)
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:
PoE Switching Modules
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.
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 E-series offers switching modules, 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 switching module 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 switching modules. 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.
Although references to “PoE,” “inline-power,” and “voice” power supplies and switching modules are
synonymous, there are only two versions: Cisco prestandard and IEEE 802.3af compliant. Every Cisco
Catalyst 4500 E-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 switching modules 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 switching modules 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 E-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 switching modules 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.
The Cisco Catalyst 4500 E-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 E-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 E-series includes 1 + 1 supervisor-engine redundancy (Cisco Catalyst
4507R-E and Catalyst 4510R-E 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 E-series compatible 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.
Chapter 1 Product Overview
The Cisco Catalyst 4500 E-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 4200 W of redundant data and PoE are required for a Cisco Catalyst
4500 E-series chassis in an AC-powered environment, Cisco offers an external AC power shelf that
houses two 2500

The Cisco Catalyst 4500 E-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 switching modules, 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 switching modules. 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
be dedicated for data (supervisor engine, fan tray, etc.), while the remaining power is passed through via
the PEM and is used for PoE.
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 DC for data and PoE applications. Up to 1400 W can
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-E with a single 15 A circuit.
Likewise, it is possible to deploy a fully populated Cisco Catalyst 4510R-E with two 20 A and one 15 A
circuits rather than a single 60 A connection, which often requires rack rewiring.

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 E-series switches support:
•Cisco Group Management Protocol, for 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.
OL-13972-01
•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.
All Catalyst 4500 series switches use a shared memory switching fabric. All forwarding decisions, QoS,
security policies and transmit queuing are implemented in the Supervisor Engine. Individual switching
modules are transparent, and only contain simple stub ASICs and PHYs; they do not perform buffering
or local switching. Classic switching modules and Classic IOS supervisor engines have a per slot
switching capacity of 6 Gbps, while E-series switching modules and supervisor engines have a per slot
switching capacity of 24 Gbps.
Frames flow into the switch through interfaces on the switching modules. Each switching module
connects to a backplane that supports a connection of up to 24 Gbps up to the supervisor engine. When
a frame reaches the supervisor engine, and a forwarding decision is made, the packet is sent out a port
on the same switching module, a different switching module, or the supervisor engine uplinks.

Classic Catalyst 4500 Series 48 port 10/100/1000 E-Series Switching modules are 8:1 oversubscribed
and Catalyst 4500 E-Series 48 port 10/100/1000 Switching modules are 2:1 oversubscribed. On both
types of switching modules, there are multiplexing ASIC's which group the front panel ports and
multiplex them to the internal switch fabric. On a 48 port 10/100/1000 Classic Catalyst 4500 Series
switching module, eight front panel ports are multiplexed into a a single, nonblocking, full-duplex
Gigabit Ethernet connection to the internal switch fabric of the Catalyst 4500 Classic Supervisors or the
Supervisor 6-E. On the Catalyst 4500 E-series 48 port 10/100/1000 switching modules, six front panel
ports are multiplexed into a 3 gigabit nonblocking, full-duplex Ethernet connection to the internal switch
fabric on the Supervisor Engine 6-E.
If the data rate received for a port presents a potential overflow condition, flow control sends pause
frames to the remote port to temporarily stop traffic and prevent frame loss. For both Classic and E-series
switching modules 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.
1-36
The 6 port 2.5:1 oversubscribed 10GbE X2 based switching module operates in a similar way. The six
front panel ports are multiplexed by groups of three into two ASICS, each having a 12 gigabit connection
into the internal switch fabric.
In a Catalyst 4500 E-series chassis with the Supervisor 6-E, there is no performance degradation when
both Classic and E-series line cards are mixed within the chassis. The Classic switching modules will
continue to operate at 6 gigabits per slot and the E-series switching modules will operate at 24 gigabits
per slot.
The Cisco Catalyst 4507R-E and Catalyst 4510R-E 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.

•Power Connection Guidelines for AC-Powered Systems, page 2-3
NoteSee 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
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 occurs.
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
expectation that the discharge is delivered to all pins of a port at once. 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.
Chapter 2 Preparing for Installation
V. The design for the common mode event is based on the
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:
–
Bare the wires on one end
–
Connect the wires to a suitable and safe earth ground
–
Connect the RJ-45 cable to a female RJ-45 connector
•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.
2-2
•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 to
properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.
•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.
CautionFor 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
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
engines, and switching modules in AC or DC environments see the Catalyst 4500 Series Module Installation Guide at:

Power Connection Guidelines for AC-Powered Systems
This section provides guidelines for connecting the Catalyst 4500 E-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.
OL-13972-01
•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
Power Connection Guidelines for AC-Powered Systems
•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 E-series switch compatible
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 AW G wi r e ( 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.
•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.
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-E with a Supervisor Engine II and two
WS-X4306-GB modules, and assumes a DC input voltage of -48
Step 1Add the power requirement for each component in your system.
•Catalyst 4503-E 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 2After 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.
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 3If 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.
Step 4Find the DC input power using the DC output power.
Step 5Divide the DC input power by the DC voltage input of –48 V to find the DC input current used by inline
Step 6Add the DC input current used by data and the DC input current used by inline devices to find the total
Ventilation
Chapter 2 Preparing for Installation
•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.

devices.
•65/48 = 1.4 Amps for inline devices.
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.
2-10
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.
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
“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.
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):

NoteAlthough 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%).

Step 3Slide the fan assembly into the chassis until the two captive installation screws make contact with the
chassis.
Step 4Using a screwdriver, tighten the two captive installation screws by turning them clockwise.
NoteTo check the operation of the fans, you need to power up the chassis.
Follow these steps to verify that the new fan assembly was installed correctly:
Step 1Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that
the fan assembly is inserted completely in the chassis and that the faceplate is flush with the switch back
panel.
Step 2The fan tray LED should light and be green.
Step 3If after several attempts the fans do not operate, or if you experience trouble with the installation (for
instance, if the captive installation screws do not align with the chassis holes), contact the Cisco TAC
for assistance.
Replacing Backplane Modules
Replacing Backplane Modules
There are 5 redundancy modules (also called mux buffers) and 1 clock module on a Catalyst 4507R-E
chassis backplane. A Catalyst 4510R-E has 8 redundancy modules on its backplane. They are accessible
from the front if the switching modules and supervisor engines are removed. There are two types of
redundancy modules, and they are interchangeable.
The clock module replacement procedure is identical to the redundancy module replacement procedure,
the connectors are the same. These modules are not hot-swappable, the switch must be taken out of
service to replace them.
To replace the backplane modules:
Step 1Make sure you are grounded with an ESD strap.
Step 2Turn off the power to the chassis.
Step 3Remove all supervisor engines and switching modules from the chassis, and find the backplane modules
you need to replace.
NoteKeep a record of switching module and their slots, so that you can put them back correctly.
NoteGeneric switching module replacement procedures are documented at:
Step 4If you are removing a clock module, remove the two screws that attach the module to the backplane.
Step 5Find the seating levers on both sides of the connector for the module you wish to replace. (See
Figure 4-19.)

Step 6To release the module from its connector, pull the levers outward with your fingernails. The module will
Step 10Push the module toward the back of the chassis and make sure it is clipped in by the levers on both sides.

Step 11Repeat Step 4 to Step 10 for the other modules you need to replace.
Step 12If you are installing a clock module, secure the module to the backplane using the screws from the earlier
removal.
Step 13Replace the supervisor engines and switching modules to their previous slots.
Step 14Restore power to the switch.
Verify the New Modules
After the switch is reassembled and power is restored, connect a terminal to the supervisor engine and
monitor the boot process. Look for the following messages (or any others), which may indicate a
problem with the replaced modules:
00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 3 is not present
00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 4 is not present
00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 7 is not present
The above messages (either at startup or output from a show logging command) indicate that the
mux-buffer is not present in slots 3, 4 and 7. You need to reinsert and reseat the modules in those slots.
If the switch has already started up, you may also verify the correct function of the new modules with
the show logging command.
This section describes how to perform a memory upgrade. You might need to upgrade memory on the
Supervisor Engine 6-E for the following reasons:
•To upgrade to a new Cisco IOS feature set or release that requires additional memory. (Memory
requirements for each feature set and release are available in the release notes for that release.)
•To use very memory-intensive features.
This document describes how to upgrade dynamic memory. The Supervisor Engine 6-E ships with 512
MB and can be upgraded to 1 GB in the form of an SDRAM miniDIMM.
Tools and Equipment Needed
You need the following tools and equipment to remove and install miniDIMMs in a Supervisor
Engine
6-E:
•Number 2 Phillips screwdriver
•Small flat-blade screwdriver
Supervisor Memory Upgrade
•ESD-preventive wrist strap
•Antistatic mat
Removing Memory
You will not need to remove the base memory to perform a memory upgrade, but it may make installing
the new memory easier. This procedure presumes you have already removed the supervisor engine from
the switch. To remove an SDRAM miniDIMM:
Step 1Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the
equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact with the
connectors.
Step 2On the mainboard, locate the SDRAM miniDIMM sockets. (See Figure 4-25.)
Figure 4-26Removing and Installing SDRAM MiniDIMMs
Supervisor Memory Upgrade
Pull the tabs away with
your thumbs, bracing your
forefingers against the
rails. The memory module
will pop loose. Then raise the
memory module to a
vertical position.
Step 4When both ends of the miniDIMM are released from the socket, grasp the ends of the miniDIMM with
your thumb and forefinger and pull it completely out of the socket. Place it in an antistatic bag to protect
it from ESD damage.
Step 5Proceed to the “Installing SDRAM MiniDIMMs” section on page 4-21.
Installing SDRAM MiniDIMMs
To install SDRAM MiniDIMMs, follow these steps:
Step 1Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the
equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact with the
connectors.
Step 2On the mainboard, locate the SDRAM miniDIMM sockets. (See Figure 4-25.)

CautionHandle the miniDIMM by the edges only; do not touch the memory modules, pins, or traces (metal
fingers along the connector edge). Handle carefully. miniDIMMs are ESD-sensitive components and can
be damaged by mishandling.
If your system has problems during start up or operation, use the information in this chapter to help
isolate the cause. Problems with the initial startup are often caused by a switching module that has
become dislodged from the backplane or a power cord that is disconnected from the power supply.
Although temperature conditions above the maximum acceptable level rarely occur at initial startup,
some environmental monitoring functions are included in this chapter because they also monitor power
supply output voltages.
Information about troubleshooting software features and configuration problems is not discussed in this
chapter.
More up to date information can be found in the release notes or Error Message Decoder tool.
Information specific to your software release can be found in the software configuration guide for that
release, or in the system message guide for your release. The following links may be useful in
combination with this chapter:
When the initial system boot is complete, verify the following:
•That the system software boots successfully
Hook up a terminal and view the startup banner. Use an RJ-45-to-RJ-45 rollover cable to connect
the console port to a PC with terminal emulation software set for 9600 baud, 8 data bits, no parity,
and 1 stop bit. Watch for any system messages after startup.
•That the power supplies are supplying power to the system
The power supply’s LEDs should be green. Use the show environment Cisco IOS command to view
power supply activity.
•That the system fan assembly is operating
Listen for fan activity. The Fan tray LED should be green during operation. Use the show
environment CiscoIOS command to view fan tray activity.
•That the supervisor engine and all switching modules are installed properly in their slots, and that
each initialized without problems
If all of these conditions are met and the hardware installation is complete, refer to the software
configuration guide and command reference publications for your switch so that you can troubleshoot
the software.
If any of these conditions is not met, use the procedures in this chapter to isolate and, if possible, resolve
the problem.
Using LEDs to Identify Startup Problems
The key to success when troubleshooting the system is to isolate the problem to a specific system
component. Your first step is to compare what the system is doing to what it should be doing. All system
states in the startup sequence are indicated by LEDs. By checking the LEDs, you can determine when
and where the system failed in the startup sequence. If you have problems after the switch is on, refer to
the following subsystem troubleshooting information and the configuration procedures in the software
configuration guide for your switch.
After you connect the power cords to your Catalyst 4500 series switch, follow these steps to determine
whether your system is operating properly:
Step 1Check the power supply LEDs:
•The LED labeled GOOD should turn green when power is applied to the supply. The LED should
•If the LED labeled GOOD does not light, or if the LED labeled FAIL lights, see the
NoteIf a power supply is installed and not connected to a power source, power supply LEDs indicate
Step 2Listen for the system fan assembly. The system fan assembly should be operating whenever system
power is on. If you do not hear it when the switch is on, see the
section on page 5-6.
Using LEDs to Identify Startup Problems
remain on during normal system operation.
“Troubleshooting the Power Supply” section on page 5-4.
a failure.
“Troubleshooting the Fan Assembly”
Step 3Check that the LEDs on the supervisor engine light as follows:
•The LED labeled STATUS flashes orange once and stays orange during diagnostic boot tests.
–
It turns green when the module is operational (online).
–
If the system software is unable to start up, this LED stays orange.
–
If the LED labeled STATUS on the supervisor engine front panel is red or orange, connect a
console to the management port and use the show
environment command to check for possible
problems.
•The Ethernet management port LED turns green when the module is operational (online) and a link
is established with another network device. If no signal is detected, the LED labeled LINK turns off.
If there is a problem with the supervisor engine, try reseating the supervisor engine in the chassis
and restarting the switch. For more information about LED meanings, refer to the
“LEDs” section
on page 1-22. For more troubleshooting information, see the “Troubleshooting Supervisor Engines”
section on page 5-10.
Step 4Verify that the LEDs labeled STATUS on each switching module are green when the supervisor engine
completes initialization.
This LED indicates that the supervisor engine and switching modules are receiving power, have been
recognized by the supervisor engine, and contain a valid Flash code version. However, this LED does
not indicate the state of the individual interfaces on the switching modules. If an LED labeled STATUS
is red or orange, try reseating the switching module or supervisor engine and restarting the switch. For
more information, see the
“Troubleshooting Switching Modules” section on page 5-8. If you determine
that the switching module is not operating, contact Cisco TAC as described in the “Some Problems and
Solutions” section on page 5-14.
OL-13972-01
Step 5If the boot information and system banner are not displayed, verify that the terminal is set for 9600 baud,
8 data bits, no parity, and 1 stop bit and connected properly to the console port.
System messages appear on the console if you have enabled console logging or appear in the syslog if
you have enabled syslog. Many messages are for informational purposes only and do not indicate an
error condition. Enter the show logging command to display the log messages. To better understand a
specific system message, refer to the system message guide for your software release. Most messages
are also documented in the Error Message Decoder tool at:
System messages specific to the system components are mentioned in the corresponding sections that
follow. If you see one of these messages, use the Decoder tool and follow the suggestion provided there.
Troubleshooting with Software
Many problems can be identified with CLI commands, and following sections will mention them as
appropriate.
Certain problems can be due to not having the right software to support your hardware. For the most
recent software release to get the current recommended version for a particular system component,
please refer to the release notes at
To help isolate a power subsystem problem, follow these steps:
Step 1Check whether the power supply LED labeled GOOD is on or the LED labeled FAIL is on. (on the DC
multi-input power supply, the LEDs are labeled INPUT 1, 2, or 3 or OUTPUT FAIL.)
Step 2If the LED labeled GOOD is off or if the LED labeled FAIL is on, take the following steps:
•Ensure that the power supply is flush with the back of the chassis.
•Unplug the power cord, loosen and reinstall the power supply, tighten the captive installation screws,
and then plug in the power cord.
Step 3If the LED labeled GOOD remains off, there might be a problem with the AC source or the power cable.
Connect the power cord to another power source if one is available. Verify that the source power is
acceptable within the specifications of the power supply.
Step 4If the LED labeled GOOD fails to light after you connect the power supply to a new power source,
replace the power cord.
NoteIf this unit has more than one power cord, repeat Step 1 through Step 4 for each power input.
Step 5If the LED labeled GOOD still fails to light when the switch is connected to a different power source
with a new power cord, the power supply is probably faulty. See the
Problems” section on page 5-5. You may need to replace the power supply.
