Thank you for purchasing the Cisco CBS Series Switch. The Cisco CBS Series Switches combine powerful network performance and reliability with a complete suite of network features that you need for a solid business network. These expandable Gigabit Ethernet switches, with Gigabit or 10-Gigabit uplinks, provide multiple management options, rich security capabilities, and Layer-3 static routing features far beyond those of an unmanaged or consumer-grade switch, at a lower cost than fully managed switches.

Warning

Suitable for installation in information Technology Rooms in accordance with Article 645 of the national Electric Code and NFPA 75.

The CBS350 “10G network port SKUs” support an Out-of-Band (OOB) port which can be used for the management network. The out-of-band and the in-band ports share the same IP routing table. Thus, the same subnet cannot be used on both the in-band and out-of-band interfaces.

The OOB port is assigned a MAC address which differs from the base MAC address and the in-band ports addresses. This MAC address is used as the source MAC address in all frames sent by the switch on the OOB port.

By default, VLAN 1 is configured with a default IP address 192.168.1.254, and can be accessed through any in-band interfaces. This default IP address is used when no other address is assigned (dynamically or statically). There is no default IP address on OOB port.

A stack can have multiple devices in it. Any 10G port of the switch can be used for stacking.

By default, the ports on the switch function as regular Ethernet ports, except if you configure them to do stacking. You cannot mix the stack speeds between the switches or ports.

At least two ports must be chosen for stacking in a given switch" and those ports must be 10Gig speed. For two switches or more to form a stack, they must be running the same version of the firmware. This is the more reason SG series switches cannot be stacked with CBS series switches. CBS250 series switches do not have stacking capabilities.

Some switches have their stack LEDs numbered 1, 2, 3, and 4 to indicate Active, Standby, and Member while the others types use the system LED flashing behavior to describe the same thing.

Note	Stack ports must have the same speed capability on the module or cable plug in.

The switch can only be stacked without Mesh topology. The switches in the same stack are connected together through their stack ports. Depending on the type of stack ports and the desired speed, you may need Cat6a Ethernet cables or Cisco approved modules or cables for the switches.

Some network switches have the ability to be connected to other switches and operate together as a single unit. These configurations are called stacks, and they are useful for quickly increasing the capacity of your network.

Note

You cannot stack the legacy switches with the new Cisco Business stackable switches. If you are stacking the legacy switches, consult the following link: https://www.cisco.com/c/en/us/support/docs/smb/switches/cisco-350x-series-stackable-managed-switches/smb5367-feature-support-comparison-between-the-cisco-stackable-manag.html

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

Cisco Business 350 Series Model

Note	Models may differ within the CBS 350 series and this is just a representation of a model within the series.

• There are 2 device types with different console interface:

  • Console port with RJ-45 and mini USB connector if both are connected the Mini USB has precedence over the RJ-45

  • RJ-45 connector only type of console.

  The console interface connects a serial cable to a computer serial port so that it can be configured using a terminal emulation program or mini USB cable (depending on the connector).

• 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. The USB port supports the FAT32 file system.

• 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 (if present) are compatible with the following Cisco SFP 1G optical modules MGBSX1, MGBLX1, MGBLH1, MGBT1, as well as other brands.

  • 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.

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

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

• 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. The table below displays the reset behavior on the switch.

  Press Type	New Behavior (Firmware 3.2 and on)	Old Behavior (Firmware prior to 3.2)
  1- 5 seconds	System LED is green, releasing button does not cause reload.	Reload
  6- 10 seconds	System LED flash green, releasing button during this period will cause device reload, but system is not set to factory default.	Reload
  11-15 seconds	System LED is green, releasing button does not cause reload	Factory default
  16-20 seconds	System LED flashes green, releasing button during this period will cause device reload to factory default	Factory default
  > 20 seconds	System LED is green, releasing button does not cause reload	Factory default

  Note

  Stack Behavior The reset button disable setting is applied to all units in the stack, meaning that if configured, the reset button on all units in the stack are disabled, and if not configured the reset button on all units in the stack are enabled. This applies also to units that join an existing stack.

• OOB Port (if present)—The Out of Band (OOB) port is a CPU Ethernet port that can be used only as a management interface. Bridging between the OOB port and the in-band Layer 2 interface is not supported. This does not appear on 250 devices.

• Multi-Gigabit Ethernet Ports (if present) —Highlighted in blue, these ports support speeds up to 2.5 Gbps or 5 Gbps on Cat5e cables. The maximum speed supported is printed on the blue shade under the port. Uplink ports on CBS350-8MGP-2X also support multi-Gigabit speed. In this case, port speed can reach 10Gbps. Most of the cabling deployed worldwide is Cat5e, and previously limited to 1 Gbps at 100 meters. Cisco multi-Gigabit Ethernet enables speeds up to 2.5 or 5 Gbps on the same infrastructure without replacing a cable.

• 60-Watt PoE Ports (if present)- The 60-Watt PoE port doubles the maximum PoE power delivered on the port to 60W.

The switch can be accessed and managed 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 and is only supported on certain models.

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

The navigation menu, located at the top right of each UI page, lists the device’s main features. You can access each feature’s UI pages using a series of cascading menus. To access an individual UI page, click the corresponding feature tab in the navigation menu to display a menu of subcategories. Select a subcategory and repeat this process until you see the desired page, and then select the page to display it in the main window.
