Q. How are the Cisco ESW 500 Series Switches used, in comparison to the Cisco Catalyst
Series Switches?
A. The Cisco Small Business Pro Series switches are designed for businesses with fewer than
100 employees. These switches were not designed with the same flexibility, scalability and
lifecycle management of the Cisco Catalyst Series switching portfolio. Cisco Catalyst Series
switches are robust, highly resilient solutions designed to deliver the performance, flexibility,
and scalability needed for the most demanding business needs. The Cisco Catalyst switches
were designed to facilitate the deployment of secure converged applications while maximizing
investment protection. The following are the reasons that Cisco Catalyst switches should be
recommended over Cisco ESW 500 Series switches:
●Scalability and high availability: Cisco Catalyst switches are designed to scale on all
fronts, including number of ports, PoE ports, and uplinks and are designed to handle a full
range of configurations and consistent look and feel that larger organizations need. In
contrast, the Cisco ESW 500 Series are designed for the needs of the small customer, they
offer few configuration options and do not scale seamlessly when moving up in size and
functionality.
●Intelligent Integrated Services: Cisco Catalyst switches are based on years of
development of the rich Cisco IOS software and offer the highest levels of application
intelligence, unified network services and integrated security features. These capabilities
deliver converged end-to-end services from the wiring closet, to campus distribution, and to
core. Although Cisco ESW 500 switches offer robust switching capabilities, its products are
not based on the IOS software and do not offer such extensive functionality.

Q&A

●Network-level Configuration and Management: Cisco Catalyst switches use CiscoWorks
LMS or command line interface (CLI) for management and configuration across the entire
portfolio. This consistency ensures that all Cisco Catalyst switches can be managed using
common management tools regardless of their size, and offers network-level management
and configuration. In contrast, the Cisco ESW 500 Series switches do not use CLI and can
only be configured using the Switch Configuration Utility device manager or Cisco
Configuration Assistant (CCA). While being friendly to use, these interfaces are not
designed to scale to multiple sites and to the needs of a commercial or enterprise customer.
It is not recommended to have a mixed environment of Cisco ESW 500 and Cisco Catalyst
Series switches, because it would be difficult to manage the entire network holistically due
to separate management tools.
●Comprehensive Support: Cisco Customer Advocacy provides a broad set of services for
the Cisco Catalyst Series switches, including Cisco SMARTnet and service by the Cisco
TAC. Cisco TAC is staffed with leading experts with years of experience in all technologies
to address any network issue the customer may have. The newly created Cisco Small
Business Support Center is based on a separate group of professionals, specifically hired
and trained in the needs of small businesses. They are limited in scope, do not have
knowledge of products beyond the Small Business range, and do not support SMARTnet or
the software upgrades that our Cisco Catalyst switches offer. Customers who chose to mix
Cisco products with the Cisco ESW 500 in their network would have to work with two
different support teams as the small business team is not equipped to diagnose and
troubleshoot cross-network issues. Also, at this time, Cisco ESW 500 series switches do not
offer an extended service contract beyond the warranty.

Technical Features
Q. What are the benefits of Power over Ethernet?
A. Power over Ethernet (PoE) can provide a lower total cost of ownership for deployments that
incorporate IP phones, wireless LAN access points, and IP video surveillance cameras, as well
as any IEEE 802.3af-compliant end devices. PoE eliminates the need for wall power to each
PoE-enabled device, by powering devices directly over the Ethernet connection, reducing re-
wiring costs when deploying IP phones and wireless LANs. PoE switches also eliminate the
need for power injectors and PoE midspans for powering IP devices.

Q. How many devices can the Cisco ESW 500 Series PoE switches power?
A. The number of devices supported depends on the power requirements for each device and the
switch model in question. The ESW-520-24P-K9 can deliver the necessary power to support
24 ports at 7.5W, 12 ports at 15.4W and any combination in between. The ESW-520-48P-K9
can deliver the necessary power to support 48 ports at 7.5W, 24 ports at 15.4W and any
combination in between. The ESW-540-24P-K9 can deliver the necessary power to support 24
ports at 7.5W, 18 ports at 15.4W and any combination in between. To help understand this
better, the below table reviews the recommended number of POE devices for 3 different
scenarios:
●Scenario 1: Assumes the PoE devices connected to the switch are all IEEE 802.3af Class 2
devices which draw less than 7.5W per device
●Scenario 2: Assumes the PoE devices connected to the switch are a mix of IEEE 802.3af
Class 2 & Class 3 devices devices which on average draw less than 11W per device
●Scenario 3: Assumes the PoE devices connected to the switch are all IEEE 802.3af Class 3
devices which draw less than 15.4W per device
Table 4. Cisco ESW 500 Series Total Power and Recommended Device Usage

A PoE device in this case could be a wireless access point, IP phone, video surveillance
camera or other network attached device. To find out the power requirement for Cisco Small
Business Pro Series products that use PoE, refer to ESW resources center at
http://www.cisco.com/go/eswhelp (live on June 4, 2009).
For all other devices, please refer to the manual for that specific device.
The ESW 500 Series Switch Configuration Utility device manager also includes a PoE budget
calculator that shows how much PoE power is being consumed based on the types of devices
connected to the switch.
Note: When using the Redundant Power Supply Unit (RPS1000) with ESW 500s, the total
available PoE power budget is a maximum of 280W.
Q. Can the Cisco ESW 500 Series switches with PoE support a device that requires more
than 15.4W from a single PoE port?
A. No.
Q. Do the Cisco ESW 500 Series PoE switches support standards-based Power over
Ethernet?
A. Yes, they support IEEE 802.3af.
Q. Do the Cisco ESW 500 Series PoE switches support Cisco pre-standard Power over
Ethernet?
A. No. For Cisco pre-standard PoE, we recommend the Cisco Catalyst 2960 Series Switches,
which support both 802.3af and Cisco pre-standard PoE.

Q. Do Cisco ESW 500 Series Switches support a redundant power supply?
A. Yes. The ESW 500 Series Switches work with the Cisco Small Business (Linksys Business
Series) RPS1000 380W Redundant Power Supply Unit, which supplies power to the switch the
instant the power begins to fail. The power supply can monitor up to six connected devices at a
time, supplying power on a first-come, first-served basis. The power supply features a
maximum capacity of 380W, making it ideally suited to support a number of Cisco Small
Business switches and network-attached storage devices. For more information, visit:
http://www.cisco.com/en/US/products/ps9940/index.html.
Management
Q. How do I configure and manage the Cisco ESW 500 Series Switches?
A. The Cisco ESW 500 Series can be configured and managed with a choice of two management
tools. It includes the embedded Switch Configuration Utility device manager, which is
available upon starting up the switch. For multiple switches and system wide deployments,
Cisco Configuration Assistant is available. Cisco Configuration Assistant is a free
downloadable at http://www.cisco.com/go/configassist (requires a cisco.com login).
*Full support for the ESW 500 Series Switches will be included in Cisco Configuration Assistant version 2.0,
available in Q2CY09. CCA version 1.9, available now, can launch the embedded Switch Configuration Utility
(Device Manager) from the topology map as shown below.

Q&A
Figure 1. Cisco ESW 500 Series Configuration Utility

Configuration Utility device manager, Cisco Configuration Assistant version 2.0 or later, or
Simple Network Management Protocol (SNMP)-capable applications using read-only MIBs.
Q. Can the Cisco Network Assistant be used to manage the Cisco ESW 500 Series?
A. No.
Q. Does the Cisco ESW 500 Series support Cisco Discovery Protocol?
A. Yes, Cisco Discovery Protocol is supported. This enables the ESW 500 Series to discover
Cisco devices and allow devices to share information about one another, simplifying the setup
and integration of an ESW 500 based network.
Q. Does the Cisco ESW 500 Series support Cisco Smartports?
A. Yes, the ESW 500 Series supports Cisco Smartports, which provide a recommended set of
configurations for devices such as computers, IP phones, and wireless access points. These
pretested baseline configurations represent Cisco best practices. Smartports are called “roles”
in the GUI. For example, in the GUI you can click on a port and then assign a role to that port.
If you assign an IP phone to a port, the port is then configured to support an IP phone,
enabling quality of service so you’ll get the voice quality you expect.
Q. Do I have to accept the suggested Cisco Smartports role?
A. No. You can choose to set the Smartports role on the port or set of ports to "Other" which
implies the port does not have a Cisco defined Smartports role assigned to it.

Security
Q. What are the primary security mechanisms in the Cisco ESW 500 Series that protect my
voice and data network?
A. ESW 500 switches provide several layers of security to protect your business. Embedded
encryption capabilities help ensure that all management traffic to and from the device is
protected with Secure Sockets Layer (SSL) encryption. The ESW 500 Series also provides
built-in support for advanced security services. These services include IEEE 802.1X port
security, which helps ensure that only authorized users and applications can access your wired
and wireless LAN, and access control lists, which can restrict access to sensitive portions of
the network and guard against attacks by keeping unauthorized users from logging in. In
addition, MAC address notification features allow administrators to track where and when
users enter the network.
Q. How can I keep unauthorized users from accessing my network?
A. The Cisco ESW 500 Series supports the IEEE 802.1X standard, which works in conjunction
with a RADIUS server to authenticate users as they access the network. The 802.1X standard
is considered port-level security and is commonly used for wireless LANs. Additionally,
portions of the network can be restricted by using access control lists. Access can be
controlled based on MAC addresses, IP addresses, or TCP/User Datagram Protocol (UDP)
ports. An additional protection method is to use port security, which limits access to the port
based on MAC addresses, helping ensure that the appropriate user is on the network.
Q. How can I protect administration passwords and traffic going to the switch during
configuration or troubleshooting?
A. To protect administration traffic (such as passwords or device configuration settings) when
configuring or troubleshooting a switch, the best approach is to encrypt the data using Secure
Sockets Layer (SSL) or Secure Shell (SSH) Protocol.
Software
Q. Is the Cisco ESW 500 Series based on Cisco IOS®Software?
A. No, the internal operating system is VxWorks.
Q. Are software updates available for the Cisco ESW 500 Series?
A. Yes, Cisco offers ongoing software fixes for the ESW 500 Series at no additional cost as part
of the product warranty.
Q. How do I get software updates for my Cisco ESW 500 Series Switch?
A. Customers that own a software license for any ESW 500 Series switch may obtain a software
update at the Cisco.com website: http://www.cisco.com/go/esw500help (live on June 4, 2009).
To download software, you will be required to log in using your Cisco.com username and
password. If you do not have a Cisco.com username, you can obtain one by clicking "Register"
at the top of any Cisco.com webpage.
