NETGEAR 7000 Series Managed Switch Administration Guide Version 7.2
Managing Switch Stacks 20-13
v1.0, May 2008
Adding a Unit to an Operating Stack
1. Make sure the redundant stack connection is in place and functional. All stack members
should be connected in a logical ring.
2. Preconfigure the new unit, if desired.
3. Install new unit in the rack. (Assumes installation below the bottom-most unit, or above the
top-most unit).
4. Disconnect the redundant stack cable that connects the last unit in the stack back up to the first
unit in the stack at the position in the ring where the new unit is to be inserted.
5. Connect this cable to the new unit, following the established order of “stack up” to “stack
down” connections
6. Power up the new unit. Verify, by monitoring the master unit console port, that the new unit
successfully joins the stack by issuing the show switch command. The new unit should always
join as a “member” (never as master; the existing master of the stack should not change).
7. If the code version of the newly added member is not the same as the existing stack, update the
code as described in section “Upgrading Firmware”.
Replacing a Stack Member with a New Unit
There are two possible situations here. First, if you replace a stack member of a certain model
number with another unit of the same model, follow the process below:
• Follow the process in section “Removing a Unit from the Stack” to remove the desired stack
member.
• Follow the process in section “Adding a Unit to an Operating Stack” to add a new member to
the stack with the following exceptions:
– Insert the new member in the same position in the stack as the one removed.
– Preconfiguration described in step “Preconfigure the new unit, if desired.” of that
procedure is not required.
Second, if you replace a stack member with another unit of a different model number, use the
following process:
• Follow the process in section “Removing a Unit from the Stack” to remove the desired stack
member.
• Remove the now-absent stack member from the configuration by issuing the command no
member command.
