Power-off procedure
Perform the following steps to power off the switch:
1. Open the rear door of the cabinet.
Check the power cabling from the M12 that is attached to the PDU that you are
servicing. These switches have dual power cords and are plugged into PDUs
with independent ac sources.
2. Removing power to a mounted M12 has an adverse affect on the customer’s
systems and networks if they are not properly prepared. Inform the customer
before you power off the M12.
Before you power off switches, make sure that the customer has removed,
dismounted, or taken them offline from their systems.
3. Turn off the ac power switches (circuit breaker) to the M12 that are connected
to the PDU that you are servicing.
4. Unplug the power cord from the customer’s ac power outlet.
5. Unplug all power cords from the PDU that you are servicing.
Removing and replacing a 16–port card or filler panel
Use this procedure to remove and replace a 16–port card or filler panel. The switch
can continue to operate during this procedure. However, if you are removing a
16–port card, any cables that are connected to that 16–port card must be
disconnected.
You can notify the switch of a hot-swap request in two ways. You can either run the
slotPowerOff and slotPowerOn commands, or click the ejector handles on the
16–port card.
Attention: Do not remove the 16–port card during diagnostic tests. Wait for the
status LED to turn off in response to the hot-swap request before you remove a
16–port card.
Attention: No user-serviceable parts are inside the 16–port card or filler panel.
Disassembling any part of a 16–port card or filler panel voids the part warranty and
regulatory certifications.
Attention: To ensure correct cooling of the chassis and protection from dust,
install a filler panel in any empty slots.
Time required
Approximately 10 minutes or less
Removing a 16–port card or filler panel
Attention: Wear a grounded ESD strap when handling a 16–port card. The
chassis has a grounding connection above the power connectors. Hold the 16–port
card by the edges of the metal pan (do not hold by ejectors).
Note: If you are replacing multiple cards, replace one card at a time. Before you
replace a port card, determine if it is the entire card or the SFPs that are
faulty.
