Cisco Catalyst 3524-PWR Desktop Switch
with Inline Power
New Member of the Catalyst 3500 Series XL Family
This product bulletin explains the positioning, features, and benefits of the new Cisco Catalyst® 3524-PWR XL desktop switch.
The Cisco Catalyst 3524-PWR XL is designed for midmarket customers (midsized companies and enterprise branch offices with 250 to
1000 employees) that want to future-proof their networks for converged applications.
Customers expecting to deploy converged network applications must consider deploying local-area network (LAN) equipment that can
support increased requirements. Switches that can treat time-sensitive traffic (such as voice and critical data traffic) with the appropriate
priority, and ensure that a network can immediately recover from network convergence or power failures, will help ready LANs for advanced
Internet applications. The Catalyst 3524-PWR XL is the industry’s first shipping desktop LAN switch with advanced features for converged
networks, such as advanced quality of service (QoS) and integrated inline power for IP phones, in a simple one-rack-unit (RU) form factor.
Using Cisco Architecture for Voice, Video, and Integrated Data (AVVID), customers can begin the migration to IP telephony today by
deploying Cisco desktop switches that deliver on QoS, high availability, integrated management, and security requirements for voice.
Part of the Catalyst 3500 series XL product line, the Catalyst 3524-PWR XL, offers stackable 10/100 and Gigabit Ethernet connectivity
with premium performance, manageability, flexibility, and unparalleled investment protection. The switch features 24 10/100 Mbps
autosensing switched ports with integrated inline power and two (2) gigabit interface connector (GBIC) 1000 Mbps ports. Integrated inline
power provides DC power to devices that can accept power over traditional UTP cabling (such as the Cisco 7900 family of IP phones). The
dual GBIC-based Gigabit Ethernet implementation offers tremendous deployment flexibility— allowing customers to use one type of stacking
and uplink configuration today, while preserving the option to change that configuration in the future.
The Catalyst 3524-PWR is ideal for customers who want to deploy the best Cisco desktop switch and who want to ensure that their
infrastructures are positioned to support applications that integrate data, voice, and video, such as IP telephony.
For customers of the Catalyst 3500 and 2900 series XL switches who want to add inline power, Cisco offers the Power Patch Panel.

New Functionality for Converged Applications
The Catalyst 3524-PWR series XL offers the QoS, high availability, integrated management, and security software features needed to equip
the LAN infrastructure for convergence. These software enhancements are available for the entire line of Catalyst 3500 and 2900 series XL
switches (except port-based reclassification, which is offered on the Catalyst 3524-PWR and Catalyst 3548 XL).
QoS Enhancements
The new QoS features focus in the areas of classification and traffic prioritization to enable proper marking and treatment of voice traffic.
• Port-based reclassification allows users to reclassify IEEE 802.1p class-of-service (CoS) values on a per-port basis (via command-line
interface [CLIs]). This feature enables finer granularity of control to implement LAN edge QoS. It helps prevent rogue PCs transmitting
tagged packets from getting higher priority relative to mission-critical applications, such as IP telephony. Note that this feature is
complementary to the port priority available on all 3500 XL and 2900 XL products for untagged packets.
• Trusted extension settings allow the switch to set trusted port settings for the PC port on Cisco IP phones, ensuring voice traffic receives
highest priority. Users can configure the Cisco IP phone via the switch so that it will either trust or untrust the priority settings of the packets
coming from the secondary data port on the phone. The trusted (untrusted) port extensions also help instruct Cisco IP phones to honor (mark
down) the CoS values seen at the PC attached to the phone. The behavior defaults to untrusted extension.
High Availability Features
Two aspects of high availability are critical for converged networks—network uptime and centralized power provisioning. Network uptime
refers to redundancy and recovery features so users do not experience network lapses. Centralized power provisioning provides a
cost-effective backup method in the event of power outage or power supply failure.
Network Uptime
• Command switch redundancy allows customers to designate a backup command switch, which takes over cluster management functions in
the event of a failure of the primary command switch.
• Circular link on a Cisco GigaStack™ daisy chain provides tolerance to a single GigaStack link failure.
• Dual gigabit uplinks provide the ability to have a redundant uplink in case the primary link goes down.
• Unidirectional Link Detection (UDLD) detects and disables unidirectional links caused by incorrect wiring or interface faults, preventing
Spanning Tree loops.
• Enhanced Spanning Tree Protocol (STP) convergence features—including Port Fast, Uplink Fast, and Per VLAN Spanning Tree
(PVST)—ensure that Spanning Tree does not degrade network performance. PVST allows users to implement redundant uplinks, while
distributing traffic loads across multiple links; this is not possible in standard STP implementations. Cisco Uplink Fast technology ensures
immediate transfer to the secondary uplink, enhancing overall network stability and reliability.

Centralized Power Provisioning
• Integrated inline power provides 48 volt DC power over standard Category 5 unshielded twisted-pair (UTP) cable up to 100 meters. Instead
of requiring wall power, terminal devices, such as Cisco IP telephones, can use power provided from the Catalyst 3524-PWR XL switch.
• Using the Phone Discovery feature, the Catalyst switch automatically detects the presence of an IP phone and supplies inline power. By
deploying Catalyst 3524-PWR XL switches with uninterruptible power supply (UPS) systems in secured wiring closets, network
administrators can ensure that power outages will not affect a company’s network telephony connections.
Integrated Management Capabilities
• Manageable through CiscoWorks2000 network management software, including new Cisco Voice Manager for IP phone management, on
a per-port and per-switch basis, providing desktop switches, core switches and WAN routers common Cisco IOS® software services and
CLI.
• Built-in Web-based management interface through a simple, standard browser such as Netscape Navigator or Microsoft Explorer.
• The Simple Network Management Protocol (SNMP) and Telnet interface provide comprehensive in-band management. A CLI-based
management console delivers detailed out-of-band management.
• Spanning Tree Root Guard (STRG) prevents devices not in the network administrator’s or service provider’s control from becoming STP
root nodes by configuring STRG on device ports it does control.
• VLAN Trunking Protocol (VTP) pruning limits broadcasts on VTP trunks. When VTP pruning is enabled, broadcast traffic is flooded only
on trunk links required to reach the destination devices.
• Auxiliary VLAN allows IP phones to be configured into a separate VLAN, separating voice traffic. This approach provides a clean migration
path for users, allowing them to create new subnets for voice traffic and add IP phones seamlessly to their networks while retaining the
current addressing scheme.
Security Enhancements
• Private VLAN edge provides security and isolation between ports on a switch, ensuring that voice traffic travels directly from its entry point
to the aggregation device through a virtual path and cannot be directed to a different port.
• Support for TACACS+ authentication enables centralized control of the switch and restricts unauthorized users from altering the
configuration.
• MAC-based port-level security prevents unauthorized stations from accessing the switch.
• User-selectable address learning mode simplifies configuration and enhances security.
• Multilevel security on console access prevents unauthorized users from altering switch configurations.
