Replacement procedures
WARNING!
• When replacing FRUs while the device is operating, ensure electrical safety.
• To avoid bodily injury and device damage, strictly follow the replacement procedures.
• 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 device is operating. If you must be next to the device on the
air outlet vent side for an extended period, avoid the air flow or take other protective measures.
CAUTION:
As a best practice to avoid data theft, remove all data from an FRU that has a storage medium, for
example, a CF card, SSD card, disk, or flash before disposal of that FRU. To remove data, format or
destroy the storage medium on the FRU.
The device uses a modular, hot-swappable architecture, and supports field replaceable units (FRUs).
You can replace the FRUs when the device is operating.
Replacing a power module
WARNING!
The power module might have a high temperature. To avoid being burnt, allow the power module to
cool before touching them.
CAUTION:
• Provide a circuit breaker for each power module. Before replacing a power module, turn off its
circuit breaker.
• 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
device damage and bodily injury.
