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 ring stack topology, break the ring and make the stack
cable connections to the new switch to close the ring.
3. Apply power to the new switch.
Connecting AC and RPS-SYS Power
AC Power
To connect a switch to the AC power source, refer to Figure 3‐8 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.
Important Considerations About Using Clear Config in a Stack
When using the clear config command (as described in the SecureStack B2 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 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: The power supply in the switch has automatic voltage sensing that allows
connection to power sources ranging from 100 to 240 VAC.
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.
