Replacement procedures
CAUTION:
•
When replacing FRUs while the switch is operating, ensure electrical safety.
•
To avoid bodily injury and device damage, follow the replacement procedures strictly.
•
Long-time exposure to strong air flow might cause discomfort. To avoid this hazard, do not stand
close to the air outlet vents while the switch is operating. If you must be next to the switch on the
air outlet vent side for an extended period, avoid the air flow or take other protective measures.
•
As a best practice to avoid data theft, remove all data from an FRU that has a storage medium,
for example, a disk or flash before disposal of that FRU. To remove data, format or destroy the
storage medium on the FRU.
The switch uses a modular, hot-swappable architecture, and supports FRUs. You can replace the
FRUs when the switch is operating.
Replacing a power module
CAUTION:
•
Provide a circuit breaker for each power module. Before replacing a power module, turn off its
circuit breaker.
•
The power module might be of high temperature. Remove it with caution.
•
To install the removed power module in the chassis again, install it after the status LED on it is off.
Strictly follow the procedures shown in
to replace a power module to avoid
device damage and bodily injury.
Figure8-1 Power module removal procedure
Figure8-2 Power module installation procedure
To replace a power module:
1.
Prepare an antistatic mat to place the removed power module.
2.
Turn off the circuit breaker.
3.
Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.
For more information, see "Attaching an ESD wrist strap."
4.
Remove the power cord.
For an AC power module, remove the cable tie, and then remove the power cord connector
from the power module.
For a DC power module, loosen the screw on the power cord connector, and then remove
the connector from the power module.
