Connectivity to the Switch Stack through Telnet
You can also Telnet to the stack manager using the commands
telnet ipaddress
and
login
.
General Practices
The following practices are highly recommended:
•
When issuing a command (such as move management, or renumber), we recommend that you allow
the command to fully complete before issuing the next command. For example, if you issue a reset
to a stack member, use the
show port
command to verify that the unit has remerged with the
stack, and all ports are joined before issuing the next command.
•
When physically removing or relocating a unit, always power down the unit before disconnecting
stack cables.
•
When reconnecting stack cables, connect them before powering up the unit, if possible. Tighten all
connector screws, where applicable, to ensure a good connection.
The following sections provide switch stack configuration scenarios. Most of the scenarios assume at
least two switches are connected through their stacking ports.
Initial Installation and Power-up of a Stack
Use the following steps to install and power-up a stack of switches:
1 Install units in rack whenever possible to prevent the units and cables from being disturbed
2 Install all stacking cables. Fully connect all cables, including the redundant stack link. We highly
recommend that a redundant link be installed because this provides stack resiliency.
3 Identify the unit to be the manager. Power this unit up first.
4 To set up a stack, complete the following steps:
a Make sure there is a 200 Series image on each box.
b If the image does not exist or needs to be updated, use TFTP or xmodem to perform the update
operation.
5 Monitor the console port. Allow this unit to come up to the login prompt. If the unit has the default
configuration, it should come up as unit #1, and will automatically become a manager unit. If not,
renumber the unit as desired.
6 If desired, preconfigure other units to be added to the stack. See
on page 32.
7 Power on a second unit, making sure it is adjacent (next physical unit in the stack) to the unit already
powered up. This will ensure the second unit comes up as a member of the stack, and not a
“Manager” of a separate stack.
8 Monitor the manager unit to see that the second unit joins the stack. Use the
show switch
command to determine when the unit joins the stack. It will be assigned a unit number (unit #2, if it
has the default configuration).
9 If desired, renumber this stack unit. See
on page 30 for
recommendations for renumbering stack members.
10 Repeat steps
to add additional members to the stack. Always power on a unit adjacent
to the units already in the stack.
