Page 39: Connecting Stacking Cables
“Connecting Stacking Cables” on page 3‐11. Otherwise, proceed to “Connecting AC and RPS‐SYS Power” on page 3‐15. Connecting Stacking Cables The stack of switches can be connected in a closed loop or daisy chained. In a closed loop all the switches are connected in sequence and the last switch in the stack is connected back to the first switch. In a daisy chain configuration the cable that would return the connection back to the first switch in a closed loop is not installed. The advantage of the closed loop is redundancy, this configuration eliminates any single point of failure. Up to eight switches can be stacked together and connected by standard UTP Category 5 or better cables. The stacking cables allow the entire stack to operate with a single IP address. Figure 3‐8 shows an example of a four‐high stack connected in a closed loop configuration. All STACK DOWN and STACK UP connectors are used in the installation. The stacking cable connections are from the STACK DOWN connector of one switch to the STACK UP connector of the next switch up in the stack. A stacking cable connection from the STACK DOWN connector of the switch at the top of the stack to the STACK UP connector at the bottom of the stack closes the loop. In a daisy chain configuration, one cable connection is not made.

As such, you can start with a single switch and add more switches as your network expands. You can also mix different products in the same family in a single stack to provide a desired combination of port types and functions to match the requirements of individual applications. In all cases, a stack of switches performs as one large product, and is managed as a single network entity. When switches are installed and connected as described back in “Connecting Stacking Cables” on page 3‐11, the following occurs during initialization: • The switch that will manage the stack is automatically established and is referred to as the Manager switch. • All other switches are established as Member switches in the stack. • The hierarchy of the switches that will assume the function of backup manager is also determined in case the current manager malfunctions, is powered down, or is disconnected from the stack. • The Console port on the manager switch remains active for out‐of‐band (local) switch management, but the Console port on each member switch is deactivated. This enables you to set the IP address and system password using a single Console port. Now each switch can be configured locally using only the manager’s Console port, or in‐band using a remote device and the CLI set of commands described in this section. For procedures used for various types of connections to the Console port, refer to “Connecting to Console Port for Local Management” on page 3‐18. Once a stack is created (more than one switch is interconnected), the following occurs: Switch (unit) IDs are arbitrarily assigned on a first‐come, first‐served basis. Switch IDs are saved against each module. Then, every time a board is power‐cycled, it will initialize with the same switch ID. This is important for port‐specific information (for example: fe.4.12 is the 12th Fast Ethernet port on switch number 4). The management election process uses the following precedence to assign a management switch: Previously assigned/elected management switch b. Management assigned priority (values 1–15) Hardware preference level d. Highest MAC Address Configuring Switches in a Stack...

Page 42: Recommended Procedures For New And Existing Stacks
The following procedures assume that all switches have a clean configuration from manufacturing. When adding a new switch to an already running stack, it is also assumed that the new switch is using the same firmware image version as other switches in the stack. -

• Use clear config to clear config parameters without clearing stack switch IDs. This command WILL NOT clear stack parameters and avoids the process of re-numbering the stack. • Use clear config all when it is necessary to clear all config parameters, including stack switch IDs and switch priority values. -

Note: If the CPU LED illuminates solid red, there was a critical failure. For more information about the LED indications and troubleshooting, refer to additional help, contact Enterasys Networks. Refer to details If the switch is a standalone switch, it will take approximately 30 seconds for the switch to start up. If the switch is a stack Manager, it can take up to 3 minutes or more to start up, depending on the number of Member switches in the stack. 3-16 Hardware Installation... -

Page 46: Stack Initialization Overview
Note: When switches are connected in a stack configuration and all stacking cables are connected before powering up the switches, one switch in the stack will be automatically designated as the Manager of the stack and its Console port will remain active. All other switches will become Member switches and their Console ports will be deactivated. -
