Connecting AC and
Adding a New Switch to an Existing Stack
Use the following procedure to install a new switch to an existing stack configuration. This procedure assumes that the new switch being added has a clean configuration from manufacturing and is running the same firmware image version as other switches in the stack.
1.Ensure that power is off on the new switch being installed.
2.Use one of the following methods to complete the stack cable connections:
–If the running stack uses a daisy chain topology, make the stack cable connections from the bottom of the stack to the new switch (that is, STACK DOWN port from the bottom switch of the running stack to the STACK UP port on the new switch).
–If the running stack uses a closed loop configuration, break the loop and make the stack cable connections to the new switch to close the loop.
3.Apply power to the new switch.
Important Considerations About Using Clear Config in a Stack
When using the clear config command (as described in the SecureStack A2 Configuration Guide) to clear configuration parameters in a stack, it is important to remember the following:
•Use clear config to clear config parameters without clearing stack switch IDs. This command WILL NOT clear stack parameters and avoids the process of
•Use clear config all when it is necessary to clear all config parameters, including stack switch IDs and switch priority values.
Connecting AC and RPS-SYS Power
AC Power
Note: The power supply in the switch has automatic voltage sensing that allows connection to power sources ranging from
To connect a switch to the AC power source, refer to Figure 3‐9 and proceed as follows:
1.Plug the power cord into the switch AC power connector.
2.Plug the other end of the power cord into a dedicated grounded AC outlet (not shown). The type of power outlet and power cord are country‐dependent.
Note: If you plan to connect all the switches quickly to allow automatic Manager selection, wait until all switches are fully operational before proceeding to the next step.
If you plan to power up each switch and allow it to become fully operational before applying power to the next switch, proceed to the next step.
