Catalyst 3524-PWR Stackable 10/100 Ethernet Switch
THE CATALYST® 3524-PWR XL SWITCH IS A MEMBER OF THE CISCO SYSTEMS CATALYST 3500 SERIES XL, A SCALABLE LINE OF STACKABLE 10/100 AND GIGABIT ETHERNET SWITCHES THAT DELIVERS PREMIUM PERFORMANCE, MANAGEABILITY, AND FLEXIBILITY WITH UNPARALLELED INVESTMENT PROTECTION.
ADVANCED QUALITY OF SERVICE (QOS) FULLY INTEGRATED WITH CISCO IP PHONES AND HIGH-AVAILABILITY NETWORK FEATURES MAKE THE CATALYST 3524-PWR XL THE PREMIER SWITCHING SOLUTION FOR CUSTOMERS AS THEY PREPARE THEIR LOCAL-AREA NETWORKS (LAN) FOR INTEGRATED VOICE, VIDEO, AND DATA APPLICATIONS.
The Catalyst 3524-PWR XL switch has 24 10/100 switched ports
with integrated inline power and two Gigabit Interface Converter
(GBIC)-based Gigabit Ethernet ports (See Figure 1). Integrated
inline power provides DC current to devices that can accept power
over traditional unshielded twisted pair (UTP) cabling (for example,
the Cisco 7900 family of Cisco IP phones). The dual GBIC-based
Gigabit Ethernet implementation provides customers with
tremendous deployment flexibility—allowing customers to
implement one type of stacking and uplink configuration today, while
preserving the option to migrate that configuration in the future.
Any customer who expects to deploy converged network
applications in the future must consider deploying LAN
equipment such as switches today that can support those
increased requirements. Such switches should be able to treat
time-sensitive traffic such as voice and critical data traffic with the
appropriate priority and ensure that the network can recover
immediately from any network convergence or power failure. The
Catalyst 3524-PWR XL is easy to deploy in traditional data LANs
and has the advanced QoS and high-availability features to
prepare networks to run applications that merge voice, video and
data traffic.

Quality of Service
All Catalyst 3500 series XL switches support LAN edge QoS
based on the Institute of Electrical and Electronic Engineers
(IEEE) 802.1p class of service (CoS), as well as port-based
prioritization. The Catalyst 3524-PWR XL supports port-based
reclassification, which allows the switch to change the CoS
settings of tagged packets on a per-port basis. For untagged
packets, the switch uses the default ingress port priority to classify
the packets. Priority scheduling is applied between the queues,
which ensures that the high priority queue is always serviced
before scheduling the lower priority traffic. These features enable
users to prioritize mission critical traffic, such as Voice over IP
(VoIP) and Enterprise Resource Planning (ERP) applications over
regular traffic, such as File Transfer Protocol (FTP) or
low-priority Web surfing traffic.
Catalyst 3500 XL and 2900 XL switches can automatically
configureVirtual LAN (VLAN) and trusted-extension settings for IP
telephones, which overcomes the management complexity of
overlaying a voice topology onto a data network and maintaining the
quality of voice traffic. With the auxiliary VLAN feature, network
administrators can segment phones into separate logical networks
even though the data and voice infrastructure is physically the same.
The auxiliary VLAN feature places the phones into their own
VLANswithout any end-user intervention. The user simply plugs the
phone into the switch, and the switch will provide the phone with the
necessary VLAN information. Trusted extension settings allow the
switch to ensure that voice traffic from an IP phone gets high-priority
treatment by controlling how traffic from a daisy-chained device is
classified.
Resiliency Features
Catalyst 3500 series XL switches have a number of hardware- and
software-based high-availability features that prevent network
and power outages from disrupting network availability, including
inline power and advanced spanning-tree convergence.
Catalyst 3524-PWR XL can provide 48-volt DC power over
standard Category 5 UTP cable up to 100 meters. Instead of
requiring wall power at every desktop, terminal devices such as IP
telephones can utilize power provided from the Catalyst
3524-PWR XL switch. With 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 building’s network telephony
connections.
Dual gigabit uplinks provide physical uplink redundancy in
case the primary link goes down. Enhanced spanning-tree
convergence features such as Port Fast, Uplink Fast and Per VLAN
Spanning Tree (PVST) ensure rapid convergence of spanning tree
in the case of link failure. PVST allows users to implement
redundant uplinks while also distributing traffic loads across
multiple links—not possible with standard shielded twisted pair
(STP) implementations. Cisco Uplink Fast technology ensures
immediate transfer to the secondary uplink, enhancing overall
network stability and reliability.
Software Management Features
Cisco Catalyst 3500 series XL switches include several
exceptional features to increase performance and manageability for
converged networks.To boost performance, Fast EtherChannel® and
Gigabit EtherChannel technology offer from 400 Mbps to 4 Gbps
high-performance bandwidth among Catalyst switches, routers, and
servers. The Cisco Group Management Protocol (CGMP) enhances
the performance of multimedia applications and reduces network
traffic by allowing a switch to selectively and dynamically forward
IP multicast traffic to targeted end stations.
Flexible Stacking with the GigaStack GBIC
The Catalyst 3500 series XL and Gigabit Ethernet-enabled
Catalyst 2900 series XL switches can be stacked using the
low-cost Cisco GigaStack GBIC. The two-port GigaStack GBIC
offers a range of highly flexible stacking and performance options.
Customers can deploy a 1 Gbps independent stack backplane in a
cascade configuration, or scale up to 5 Gbps of bandwidth in a star
configuration using the Catalyst 3508G XL Gigabit Ethernet
aggregation switch (See Figure 2). Network managers may use one
or both of the available GBIC ports to create high-speed uplinks to
the network core, using standard Gigabit Ethernet or Gigabit
EtherChannel technology. High levels of stack resiliency can also be
implemented by deploying dual redundant Gigabit Ethernet
Uplinks, a redundant GigaStack loopback cable, Uplink Fast for
high-speed uplink failover, and per VLAN Spanning Tree (PVST+)
for uplink load balancing. This Gigabit Ethernet flexibility makes
the Catalyst 3500 series XL an ideal LAN edge complement to the
Cisco Catalyst 6500 family of Gigabit Ethernet-optimized core
LAN switches.
Figure 2 Customers Can Start with a Low-cost GigaStack, GBIC-based, 1 Gbps, Independent Stack Backplane. At Any Point, Users Have The Option to Increase Their
Stack Performance to 5 Gbps Using The Same GigaStack GBICs In Combination with the High-performance Catalyst 3508G XL Gigabit Ethernet Aggregation Switch
Cisco Switch Clustering
Breakthrough Cisco switch clustering technology enables up to 16
interconnected Catalyst 3500 XL, Catalyst 2900 XL, and Catalyst
1900 switches—regardless of geographic proximity—to form a
single IP management domain. Switch-cluster connectivity
options for the Catalyst 3500 series XL include Ethernet, Fast
Ethernet, Fast EtherChannel, low-cost Cisco GigaStack GBIC,
Gigabit Ethernet, and Gigabit EtherChannel connectivity. Because
the technology is not limited by proprietary stacking modules or
stacking cables, Cisco switch clustering expands the traditional
stacking domain beyond a single wiring closet. Catalyst 3500 XL
switches can be configured either as command or member
switches in a Cisco switch stack or cluster. The command switch
serves as the single IP address management point and disburses all
management instructions dictated by the network administrator.
Command switches can cluster up to 15 additional interconnected
member switches regardless of interconnection media.
