Manual for CBS Series

Introduction

The Cisco CBS Series Switches offer powerful network performance and reliability for business networks. These switches provide expandable Gigabit Ethernet with Gigabit or 10-Gigabit uplinks, offering multiple management options, robust security, and Layer-3 static routing, at a lower cost than fully managed switches.

Before You Begin

Before installation, ensure you have RJ-45 Ethernet cables (Category 5e or higher for standard ports, Category 6a or higher for 10G ports), installation tools, and the rack-mount kit. The rack-mount kit includes rubber feet for desktop placement and brackets/screws for rackmounting. Replacement screws should have a 6.9 mm head diameter and a 5.9 mm head-to-base length.

Rack Mounting Switch

Switches can be mounted in any standard 19-inch wide rack, requiring 1 rack unit (RU) of space (1.75 inches high). For stability, load heavier devices at the bottom of the rack. Attach the supplied brackets to the sides of the switch using the provided screws, then install the switch into the rack.

Wall Mounting a Switch

Switches can be mounted on a wall using wall studs or a plywood backboard. Caution: Do not wall-mount with the front panel facing up to ensure proper airflow and cable access. For 24-port switches, attach 19-inch brackets to each side and then mount. For 8-port switches, use a screw template to mark and drill holes, then attach mounting screws and slide the switch into place.

Stacking the Switches

Any 10G port can be used for stacking. By default, ports function as Ethernet ports unless configured for stacking. Speeds cannot be mixed between stacked switches or ports. Stacking can be done in native mode (all units same type) or hybrid mode (mixed types).

Power over Ethernet Considerations

Some models support Power over Ethernet (PoE), indicated by a 'P' in the model number. These switches are Power Sourcing Equipment (PSE) and can supply power to Powered Devices (PD). Caution: Connect PoE switches only to PoE networks, not to the outside plant. Be aware of potential false detection where a PSE might mistake another PSE for a PD, which can cause improper operation. Disable PoE on ports connecting to other PSEs and power up PSE devices before connecting them.

Front Panel

The front panel houses ports, LEDs, and the Reset button. It includes RJ-45 Ethernet ports, SFP+ ports for modules, console ports (RJ-45 and/or mini-USB), and a USB port for configuration file management. Models may vary.

Front Panel LEDs

System LED indicates power status, boot process, self-tests, or IP acquisition. Amber indicates a hardware/firmware failure or configuration error. Stack ID and Active Unit ID LEDs indicate stacking status. The System LED also flashes to indicate the unit ID of each member in a stack.

Configuring Switches

Switches can be configured via a web-based interface or console port. The default settings are username 'cisco' and password 'cisco', with a LAN IP of 192.168.1.254. Accessing the web interface requires knowing the switch's IP address. The System LED flashes continuously if the default IP is in use, and is steady green when a DHCP or static IP is assigned.

Configuring Your Switch Using the Console Port

For console configuration, connect a computer via a console cable and use a terminal emulation program (like HyperTerminal) with specific parameters (115200 bits per second, 8 data bits, no parity, 1 stop bit, no flow control). After logging in, change the default credentials and configure static IP settings if not using DHCP.

Restoring Factory Default Settings

To restore factory defaults, disconnect the switch from the network or disable DHCP servers. Then, with the power on, press and hold the Reset button for more than ten seconds.

Navigation

The UI navigation menu provides access to device features through cascading menus. Users can choose between Basic and Advanced display modes for configuration options. Switching modes may cause unsaved configurations to be deleted.
