Q&A

Cisco Catalyst Express 500 Series Switches

General

Q. What are the Cisco Catalyst Express 500 Series Switches?

A. The Cisco®Catalyst®Express 500 Series Switches deliver networking tailored for businesses

with fewer than 250 employees. Powered by Cisco technology and managed through a GUI,

they are nonblocking, wire-speed, Layer 2-managed Fast Ethernet and Gigabit Ethernet

switches. The user-friendly GUI makes setting up, running, and troubleshooting networks

easy. Built-in Cisco Smartports with preset Cisco recommended network configurations,

quality of service (QoS), and security settings allow for transparent integration of data, video,

IP communications, and wireless LAN applications.

Table 1 gives descriptions of the switches.

Product Positioning

Q. How are the Cisco Catalyst Express 500 Series Switches positioned relative to the

Cisco Catalyst 2960 Series Switches?

A. The Cisco Catalyst 2960 Series Switches are entry-level enterprise switches, whereas Cisco

Catalyst Express 500 Series Switches are targeted at businesses with 20 to 250 employees.

Enterprise branch offices should be deploying Cisco Catalyst 3000 and 2960 Series Switches

because of the need to actively manage, upgrade, and configure a large number of devices.

Q&A

Technical Details

Management

Q. How do I manage the Cisco Catalyst Express 500 Series Switches?

A. The Cisco Catalyst Express 500 Series Switches can be managed either through the

embedded Device Manager or with Cisco Network Assistant, downloadable from the Cisco

Website at no charge: http://www.cisco.com/go/cna.

Q. Is there a command-line interface (CLI) on the Cisco Catalyst Express 500 Series

Switches?

A. No, these switches cannot be managed through a CLI.

Q. Are there plans to add a CLI or Telnet to Cisco Catalyst Express 500 Series Switches?

A. No, there are no plans to add a CLI or Telnet to these switches.

Q. Can Cisco Catalyst Express 500 Series Switches be remotely configured?

A. Yes, Cisco Catalyst Express 500 Series Switches can be remotely configured using the

embedded Device Manager or with Cisco Network Assistant.

Q. Can Cisco Catalyst Express 500 Series Switches be remotely monitored?

A. Yes, Cisco Catalyst Express 500 Series Switches can be remotely monitored using the

embedded Device Manager, the Cisco Network Assistant, or Simple Network Management

Protocol (SNMP)-capable applications using read-only MIBs.

Q. Do I have to accept the suggested Smartports role?

A. No, you can choose not to accept the suggested Smartports role.

Interoperability

Q. Will Cisco Catalyst Express 500 Series Switches interoperate with other Cisco

switches?

A. Yes, these switches interoperate with other Cisco switches.

Q. Will Cisco Catalyst Express 500 Series Switches interoperate with other vendors’

switches?

A. Yes, these switches interoperate with other vendors’ switches. You can apply Cisco

Smartports “switch” port role to the port, but it will not autosuggest a Smartports port role or

detect configuration errors.

Power

Q. Is there redundant-power-supply support on the Cisco Catalyst Express 500 Series

Switches

A. The Cisco Redundant Power System (RPS) 675 supports the Cisco Catalyst Express 500-

24PC only. It does not support the Cisco Catalyst Express 500-24TT, 500-24LC, or 500G-

12TC.

Q. Do Cisco Catalyst Express 500 Series Switches support the IEEE 802.3af inline power

standard and Cisco Prestandard Inline Power?

A. Yes, these switches support both IEEE 802.3af inline and Cisco Prestandard Inline Power.

Q&A

Q. Which ports support inline power on the Cisco Catalyst Express 500-24LC?

A. Ports 1 through 4 on the Cisco Catalyst Express 500-24LC can support up to 15.4 watts (W)

at the same time.

Q. What is the maximum power per port supported on the Cisco Catalyst Express 500-

24PC and the Cisco Catalyst Express 500-24LC?

A. For the Cisco Catalyst Express 500-24LC, each of the four PoE ports can support up to

15.4W per port. All four ports can supply 15.4W at the same time. For the Cisco Catalyst

Express 500-24PC, each of the twenty-four 10/100 ports can support up to 15.4W per port. All

24 ports can supply 15.4W at the same time. There is no need to do creative power budgeting

or worry about exceeding the power limit or adding an external power shelf.

Q. Do the Cisco Catalyst Express 500-24PC and 500-24LC support power management?

A. No, because the Cisco Catalyst Express 500-24PC and 500-24LC can support the IEEE

maximum of 15.4W on all PoE-capable ports simultaneously, power management is not

necessary on these switches.

Q. What are the power requirements of the Cisco Catalyst Express 500 Series Switches?

A. Table 2 lists the power requirements of the Cisco Catalyst Express 500 Series Switches.

Table 2. Power Requirements

Switch Model Power Consumption

(maximum) Power Dissipation Power Rating

Cisco Catalyst Express 500-

24TT (WS-CE500-24TT) 30W or 102 BTUs per hour 30W 0.050kVA

Cisco Catalyst Express 500-

24LC (WS-CE500-24LC) 110W or 375 BTUs per hour 45W 0.1 20kVA

Cisco Catalyst Express 500-

24PC

(WS-CE500-24PC)

460W or 1570 BTUs per hour 90W 0.460kVA

Cisco Catalyst Express

500G-12TC

(WS-CE500G-12TC)

45W or 154 BTUs per hour 45W 0.075kVA

Q. Why are some of the power dissipation numbers lower than the power consumption

numbers?

A. The difference between the power consumption number and the power dissipation number is

the amount of power dissipated in the powered end devices.

SFP Support

Q. Do the Cisco Catalyst Express 500 Series Switches support the Cisco Catalyst 3560

Small Form-Factor Pluggable (SFP) interconnect cable?

A. No, the Cisco Catalyst Express 500 Series Switches do not support the Cisco Catalyst 3560

SFP interconnect cable. Simply use the 10/100/1000BASE-T port to interconnect adjacent

switches.

Q. Which SFPs are supported on the Cisco Catalyst Express 500 Series Switches?

A. The Cisco Catalyst Express 500 Series Switches support the following Cisco SFPs:

●100BASE-BX-10D

●100BASE-BX-10U

●100BASE-FX-FE

Q&A

●100BASE-FX-GE

●100BASE-LX

●1000BASE-LX/LH

●1000BASE-SX

Q. Are the Cisco Coarse Wavelength-Division Multiplexing (CWDM) and Dense

Wavelength-Division Multiplexing (DWDM) SFPs supported on the Cisco Catalyst

Express 500 Series Switches?

A. No, the Cisco CWDM and DWDM SFPs are not supported.

Security

Q. What do the different levels of security mean in Cisco Catalyst Express 500 Series

Switches?

A. There are three levels of access security. The default level is Low.

●Low: Only one device, or one PC and IP phone, is allowed per port.

●Medium: Only authorized devices (via MAC address) are allowed on the network.

●High: Only authorized devices and authenticated users (via IEEE 802.1X) are allowed on

the network.

Software Updates

Q. How do I get a “no additional cost” Cisco IOS Software update for my Cisco Catalyst

Express 500 Series Switch?

A. Customers that own a software license for the Cisco Catalyst Express 500 series may obtain a
