2.
Switch IDs are saved against each module. Then, every time a board is power‐cycled,
it will initialize with the same switch ID. This is important for port‐specific
information (for example: ge.4.12 is the 12th Gigabit Ethernet port on switch # 4).
3.
The management election process uses the following precedence to assign a
management device:
a.
Previously assigned / elected management switch
b. Management assigned priority (values 1‐15)
c.
Hardware preference level
d. Highest MAC Address
Recommended Procedures to Install New and Existing Stacks
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 High‐Speed Stacking Cables" on page 3‐10.
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
PoE Power" on page 3‐15).
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.
