Replacing a module
Make sure to follow the instructions and notes to use the card safely. There is a risk
of death or serious injury. For more information, see the descriptions from page 55.
● Do not replace two or more switch modules, pass-through cards, EM cards, fan
units, power units, or other modules at the same time.
● Do not place your hands inside the Blade Enclosure.
Switch module/pass-through card
Switch modules and pass-through cards can be replaced even if the Blade Enclosure is powered on
(i.e., CPU blades and switch modules and pass through cards in other slots are running).
1. Check which switch module or pass- through card to replace.
Important
● When you replace a switch module or pass-through card, communication via the switch
module or pass-through card becomes unavailable.
● When you replace a switch module or pass-through card while the Blade Enclosure is
powered on, the replacement should be done quickly. Because cooling efficiency is
reduced if a switch module or pass-through card is removed, attach a slot cover to the slot
of the removed switch module or pass-through card.
2. Remove the cables connected to the switch module/pass-through card.
3. Remove the switch module or pass-through card from the slot. For information on removing
switch modules and pass-through cards, see “Switch module/pass-through card” in the User‟s
Guide of the Blade Enclosure.
4. Install the replacement card in the slot. (For information on how to install this card see
“Installing the card.”)
If the card is not powered on automatically after installation, run the following command to
power on the card:
(1) Check that the EM card is powered on.
(2) Check that you are logged on as “Administrator” or with the access rights of an
ADMINISTRATOR or OPERATOR from the CLI of the EM serial console or the EM
console. If you are not, log on as “Administrator” or with the access rights of an
ADMINISTRATOR or OPERATOR.
(3) From the CLI, run the following command. For details, see “Command specifications” in
the User‟s Guide of the Blade Enclosure.
Powering on:
Powers on the specified switch module or pass-through card:
POWERON SWITCH <slot number>
5. Check that the STATUS LED of the switch module/pass-through card is lit green.
