Hot Swapping a Switching Module

4. Carefully remove the switching module from the chassis and put it in a safe place. (See
Removing a Switching Module on page 3-6 for instructions on removing a switching
module.) The MPX’s OK2 LED will flash amber 1 or 2 times, then return to normal flashing
green. In addition, the swap time will reset to its original value. (For example, if you set
the swap time to 15 minutes in step 1, you will have 15 minutes again, regardless of how
much time has elapsed.)
♦ Warning ♦
Removing or inserting the switching module while the
MPX’s OK2 LED is flashing amber can cause the system
to reset.
5. Carefully insert the new switching module into the chassis. (See Installing a Switching
Module on page 3-4 for instructions on inserting a switching module.)
♦ Caution ♦
When re-installing a module during a hot swap, it must
make a proper connection to the switch backplane.
The connection is made when you close the card ejec-
tors. Always close the card ejectors firmly and briskly,
without hesitation. Closing them too slowly can cause
the switch to halt or restart.
The
MPX’s OK2 LED will flash amber 1 or 2 times, then return to normal flashing green. If,
after hot-swapping modules, the MPX’s OK2 LED continues to flash amber for more than
about 8 seconds, it means that the switch needs to be reset.
The swap time will again reset to its original value.
6. Re-insert the cables that were removed in step 3 into the new switching module.
7. Enter
reset followed by the slot number for the new switching module. For example, if
the new switching module is in slot 4, you would enter
reset 4
at the system prompt. Next, the switch will prompt you to confirm the reset. The follow-
ing is an example of the display for an
ESX module. The display for other types of switch-
ing modules will be similar.

Press y and then press <Enter>. If the switching module is in slot 4, a message similar to
the following will be displayed.

8. The MPX’s OK2 LED will flash amber 1 or 2 times, then return to normal flashing green.
The switching module’s OK1 LED will turn from amber to solid green and the OK2 LED
will be blinking green. If the OK1 LED on the switching module is amber, then the hard-
ware has failed diagnostics or the corresponding image file for the module is not in flash
memory. If the OK2 LED on the switching module is solid amber, then the module failed
to download software from the MPX.
