Cisco Systems SLM224G4PS, SLM248G4PS manual Connect port G1 on Unit 2 to port G2 on Unit

Chapter 3 Installation

1.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 1.

2.Connect the cable’s other end to port G2 on Unit 2.

3.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 2.

4.Connect the cable’s other end to port G2 on Unit 3.

5.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 3.

6.Connect the cable’s other end to port G2 on Unit 4.

7.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 4.

8.Connect the cable’s other end to port G2 on Unit 5.

9.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 5.

10.Connect the cable’s other end to port G2 on Unit 6.

11.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 6.

12.Connect the cable’s other end to port G2 on Unit 1.

For a stack with less than 6 switches, the steps are similar except that port G1 of the last switch in the stack must be connected back to port G2 of the first switch in the stack.

The following is an example of setting up a stacked configuration using three SLM248G4PS switches.

1. Connect port G1 on Unit 1 to port G2 on Unit 2.

Connect Unit 1 to Unit 2

2. Connect port G1 on Unit 2 to port G2 on Unit 3.

Connect Unit 2 to Unit 3

3. Connect port G1 on Unit 3 to port G2 on Unit 1.

Connect Unit 3 to Unit 1

For detailed information on switch stacking, refer to “Appendix B: About Switch Stacking.”

For more information on stack configuration using the Console Interface, refer to “Stack Configuration” and “System Mode” in “Chapter 4: Configuration Using the Console Interface” .

For more information on stack configuration using the Web-based Utility, refer to “Setup > Stack Management” in “Chapter 5: Configuration Using the Web-based Utility”.

Reassigning a Slave Unit as the Master Unit

You can reassign a slave unit so that it becomes the master unit. To do this, you swap their unit numbers. For example, to make slave unit 5 be the master, you change the master’s unit number from 1 to 5 and the slave’s unit number from 5 to 1. To change the unit numbers, you can use either the Web-based utility or the console interface.

The following describes the procedure for changing a slave unit into the master unit. In this example, unit 5 is made the master unit.

1.Swap the unit numbers. That is, change the unit number of the current master from 1 to 5, and change the unit number of slave unit 5 from 5 to 1. (The order in which these are performed is not significant.)

2.Power off the new unit 5 (the former master unit).
