Upgrading the Firmware on the Core Switch 2/64
Note: The procedure below only applies to upgrading firmware from versions v4.0.0d
or later. When upgrading a
Core Switch 2/64
that is running v4.0.0c or less, use the
“ Downloading Firmware to a Single CP on a Core Switch 2/64 ” on page 84, or call
your service personnel.
The following firmware upgrade process is specific to the Core Switch 2/64.
The Core Switch 2/64 has four IP addresses: one for each switch (switch 0 and
switch 1) and one for each of the two CPs (CP0 in slot 5 and CP1 in slot 6). When
upgrading the firmware in the Core Switch 2/64, the firmwaredownload command
will automatically load new firmware in to both the Active CP and Standby CP;
this is the default behavior in v4.1, and no special actions are required.
To upgrade the firmware on a Core Switch 2/64:
1. Verify that the FTP service is running on the host workstation (or on a
Windows machine).
2. Telnet in to the Core Switch 2/64 as the admin user.
Example
3. Telnet in to either logical switch 0 or 1.
Example
4. Enter the haShow command to determine which CP is the Active, and
which is the Standby.
Also, confirm that the two CPs are in sync. CPs must be in synch to provide the
non-disruptive download.
Example:
switch:admin>
Telnet 192.168.174.91
switch:admin> hashow
Local CP (Slot 6, CP1): Active
Remote CP (Slot 5, CP0): Standby
HA Enabled, Heartbeat up, HA State is in Sync
