Configuring Switches in a Stack

3.The management election process uses the following precedence to assign a management switch:

a.Previously assigned/elected management switch

b.Management assigned priority (values 1–15)

c.Hardware preference level

d.Highest MAC Address

Recommended Procedures for New and Existing Stacks

Important

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.

Installing a New Stackable System of Up to Eight Switches

Use the following procedure to install a new stack of up to eight switches out of the box. Before applying power, make all physical connections with the stack cables as described in “Connecting Stacking Cables” on page 3‐7.

1.Once all of the stack cables have been connected, individually power on each switch from top to bottom (connecting power to a switch is described in “Connecting AC and RPS‐SYS Power” on page 3‐12).

If the switches are powered on almost simultaneously, the system will automatically select the first one that powers up as the Master switch and the others as Member switches. The switches are assigned unit IDs in the order that they become fully operational.

You can control the unit ID assignment according to the physical position in a stack. When you power up each switch and allow it to become fully operational before applying power to the next switch, the first one becomes the Manager and all the next switches will join that stack (regardless of Priority, Firmware Revision, or MAC Address). The switches are assigned unit IDs in the order that you power on each switch.

Note: Once switch IDs are assigned, they are persistent and will be retained during a power cycle to any or all of the switches.

2.(Optional) If desired, change the management switch using the set switch movemanagement command as described in the SecureStack A2 Configuration Guide.
