Adding A New Switch To An Existing Stack; Connecting Ac Power - Enterasys B5G124-24 Hardware Installation Manual

Connecting AC Power

Adding a New Switch to an Existing Stack

Use the following procedure to install a new switch to an existing stack configuration.
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:
–
–
3. Apply power to the new switch.
When using the clear config command (as described in the Enterasys B5 CLI Reference) 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.

Connecting AC Power

To connect a switch to the AC power source, refer to Figure
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.
2-10 Installation
Note: 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. The
new switch being added also must have the same license as the manager switch.
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 connector from the
bottom switch of the running stack to the STACK UP connector 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.
Important Considerations About Using Clear Config in a Stack
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.
