Power over Ethernet Considerations

Some switches support PoE while others do not. The switch models that support PoE have a P in their model number, such as: CBSxxx-xxP-xx. If your switch is one of the Power over Ethernet (PoE) models, consider the following power requirement.

Danger

The switch is to be connected only to PoE networks without routing to the outside plant.

AF/AT6*TPS238848-Port Gigabit PoE Smart Switch with 10G Uplinks

Consider the following when connecting a PoE switch. The PoE switches are PSE (Power Sourcing Equipment) that are capable of supplying DC power to attaching powered devices (PD). These devices include VoIP phones, IP cameras, and wireless access points. The PoE switches can detect and supply power to pre-standard legacy PoE PD. Due to the PoE legacy support, it is possible that a PoE switch acting as a PSE may mistakenly detect and supply power to an attaching PSE, including other PoE switches, as a legacy PD. Even though PoE switches are PSE, and as such should be powered by AC, they could be powered up as a legacy PD by another PSE due to false detection. When this happens, the PoE switch may not operate properly and may not be able to properly supply power to its attaching PDs.

To prevent false detection, you should disable PoE on the ports on the PoE switches that are used to connect to PSEs. You should also first power up a PSE device before connecting it to a PoE switch. When a device is being falsely detected as a PD, you should disconnect the device from the PoE port and power recycle the device with AC power before reconnecting its PoE ports.

Front Panel

Note

Front Panel

The ports, LEDs, and Reset button are located on the front panel of the switch, as well as the following components:

Cisco Business 250 Series Model

Models may differ within the CBS 250 series and this is just a representation of a model within the series.

• Console port with RJ-45 and mini-USB connectors. The console connects a serial cable to a computer serial port so that it can be configured using a terminal emulation program.

Note

Only certain models support this featue.

• USB Port—The USB port connects the switch to a USB device so that you can save and restore the configuration files, firmware images, and SYSLOG files through the connected USB device.

• RJ-45 Ethernet Ports—The RJ-45 Ethernet ports connect network devices, such as computers, printers, and access points, to the switch.

• SFP+ Port (if present)—The small form-factor pluggable plus (SFP+) are connection points for modules so that the switch can link to other switches. These ports are also commonly referred to as mini 10GigaBit Interface Converter ports. The term SFP+ is used in this guide.

• The SFP+ ports are compatible with the following Cisco SFP 1G optical modules MGBSX1, MGBLX1, MGBLH1, MGBT1, as well as other brands.

• The Cisco SFP+ Copper Cable modules that are supported in the Cisco switches are: SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M.

• Small form-factor pluggable (SFP) ports are connection points for modules, so the switch can link to other switches.

• The LEDs of the corresponding RJ-45 port flash green to respond to the SFP interface traffic.

• Some SFP interfaces are shared with one other RJ-45 and SFP+ port, called a combo port. When the SFP is active, the adjacent RJ-45 port is disabled.

• Reset button is used to reset or reboot the switch. To reboot the switch, press the Reset button for less than 10 seconds.

indicates its Stack ID.

• Flash = LED going off and then on again.

• According to unit ID of the unit. This means

• Unit 1 (if not active unit) - system LED will flash 1 time

• Unit 2 (if not active unit) - system LED will flash 2 times

• Unit 3 - system LED will flash 3 times

• Unit 4 -system LED will flash 4 times;

• The duration of each flash (LED off time) will be as follows:

• LED off time (in each flash) ~ 0.5 seconds.

• “Interim” LED on (between 2 LED offs) ~ 0.5 seconds

• If a member unit is removed from the stack, its system LED will continue to flash according to above definition.

The following are per port LEDs:

• LINK/ACT—(Green) Located on the left of each port. The LED lights steady when a link between the corresponding port and another device is detected, and flashes when the port is passing traffic.

• SFP+ (if present)—(Green) Located on the right of a 10G port. The LED lights steady when a connection is made through the shared port, and flashes when the port is passing traffic.

• XG—(Green) Located on the right of a 10G port. The LED lights steady when another device is connected to the port, is powered on, and a 10 Gbps link is established between the devices. When the LED is off, the connection speed is under 10 Gbps or nothing is cabled to the port.

• Gigabit—(Green) Located on the right of the OOB and 1G port. The LED lights steady when another device is connected to the port, is powered on, and a 1000 Mbps link is established between the devices. When the LED is off, the connection speed is under 1000 Mbps or nothing is cabled to the port.

• PoE (if present)—(Amber) Located on the right of the port. The LED lights steady when power is being supplied to a device attached to the corresponding port.

Configuring Switches

The switch can be accessed and managed by two different methods; over your IP network using the web-based interface, or by using the switch’s command-line interface through the console port. Using the console port requires advanced user skills.

The following table shows the default settings used when configuring your switch for the first time.

Default ValueParameter

ciscoUsername

ciscoPassword

192.168.1.254LAN IP

Configuring Your Switch Using the Web-based Interface

Configuring Switches

To access the switch with a web-based interface, you must know the IP address that the switch is using. The switch uses the factory default IP address of 192.168.1.254, with a subnet of /24. When the switch is using the factory default IP address, the System LED flashes continuously. When the switch is using a DHCP server-assigned IP address or an administrator has configured a static IP address, the System LED is a steady green (DHCP is enabled by default).

If you are managing the switch through a network connection and the switch IP address is changed, either by a DHCP server or manually, your access to the switch will be lost. You must enter the new IP address that the switch is using into your browser to use the web-based interface. If you are managing the switch through a console port connection, the link is retained.

To configure the switch using the web-based interface:

Step 1 Power on the computer and your switch.

Step 2 Connect the computer to any network port.

Step 3 Set up the IP configuration on your computer.

a) If the switch is using the default static IP address of 192.168.1.254/24, you must choose an IP address for the computer

in the range of 192.168.1.2 to 192.168.1.253 that is not already in use.

b) If the IP addresses will be assigned by DHCP, make sure that your DHCP server is running and can be reached from

the switch and the computer. You may need to disconnect and reconnect the devices for them to discover their new IP addresses from the DHCP server.

Note

Details on how to change the IP address on your computer depend upon the type of architecture and operating system that you are using. Use your computers local Help and Support functionality and search for “IP Addressing.”

Step 4 Open a web browser window. Step 5 Enter the switch IP address in the address bar and press Enter. For example, http://192.168.1.254.

Step 6 When the login page appears, choose the language that you prefer to use in the web-based interface and enter the username

and password.

Step 8 Enter a new username and password and confirm.

Get To Know Your Switch

Note

Password complexity is enabled by default. The password must comply with the default complexity rules.

Step 9 Click Apply.

Caution

Make sure that any configuration changes made are saved before exiting from the web-based interface by clicking on the Save icon. Exiting before you save your configuration results in all changes being lost.

The Getting Started page opens. You are now ready to configure the switch. Refer to the Administration Guide or see the help pages for further information.

Configuring Your Switch Using the Console Port

To configure the switch using the console port, proceed with the following steps:

Step 1 Connect a computer to the switch console port using a Cisco console cable (purchased separately) or a cable with mini

USB connector.

Step 2 Start a console port utility such as HyperTerminal on the computer.

Step 3 Configure the utility with the following parameters:

• 115200 bits per second

• 8 data bits

• no parity

• 1 stop bit

• no flow control

Step 4 Enter a username and password. The default username is cisco, and the default password is cisco. Usernames and passwords

are both case sensitive.

If this is the first time that you have logged on with the default username and password, the following message appears:

Please change your username AND password from the default settings. Change of credentials

is required for better protection of your network.

Please note that new password must follow password complexity rules

Step 5 Set a new administrator username and password.

Caution

Make sure that any configuration changes made are saved before exiting.

You are now ready to configure the switch. See the CLI Guide for your switch.

Navigation

Note

Console access also provides additional interfaces for debug access which are not available via the web interface. These debug access interfaces are intended to be used by a Cisco Support Team personnel, in cases where it is required to debug device’s behavior. These interfaces are password protected. The passwords are held by the Cisco support team. The device supports the following debug access interfaces:

• U-BOOT access during boot sequence

• Linux Kernel access during boot sequence

• Run time debug modes - allows Cisco support team to view device settings and apply protocol and layer 1 debug commands and settings. The run time debug mode is accessible over telnet and SSH terminals in addition to console.

Navigation

If you are not using DHCP on your network, set the IP address type on the switch to Static and change the static IP address and subnet mask to match your network topology. Failure to do so may result in multiple switches using the same factory default IP address of 192.168.1.254.

Source MAC Address

Source MAC Value

Mask

Destination MAC Address

Destination MAC Value

Destination MAC Wildcard Mask

Time Range Name

Select Any if all source address are acceptable or User defined to enter a source address or range of source addresses.

Enter the MAC address to which the source MAC address is to be matched and its mask (if relevant).

Enter the mask to define a range of MAC addresses.Source MAC Wildcard

Select Any if all destination addresses are acceptable or User defined to enter a destination address or a range of destination addresses.

Enter the MAC address to which the destination MAC address is to be matched and its mask (if relevant).

Enter the mask to define a range of MAC addresses. Note that this mask is different than in other uses, such as subnet mask. Here, setting a bit as 1 indicates don't care and 0 indicates to mask that value.

Note

Given a mask of 0000 0000 0000 0000 0000 0000 1111 1111 (which means that you match on the bits where there is 0 and don't match on the bits where there are 1's). You need to translate the 1's to a decimal integer and you write 0 for each four zeros. In this example since 1111 1111 = 255, the mask would be written: as 0.0.0.255.

If Time Range is selected, select the time range to be used. Time ranges are defined in

Time Range, on page 59. This field is only displayed if a Time Range was previously

created.
