Figure 29 Connecting the grounding cable
If there is no grounding point on the rack, you can attach the grounding cable to a grounding strip. The
installation procedures are similar.
Installing the power system
The S9500E switches support both AC and DC power supply modes. You can select either AC or DC
power supply mode as needed. 1+1 redundancy is recommended.
CAUTION:
•
Hold a power supply or sub power supply by the bottom when moving it. Never attempt to lift a power
supply or sub power supply with its handle because the handle is not designed to support weight. Doing
so might result in bodily injury or damage to the power supply or sub power supply.
• Make sure the power switch of the power supply or sub power supply is in the OFF position before
installing them.
Installation preparation
• Put on an ESD-preventive wrist strap and make sure it is properly grounded.
• Remove the blank panel (if any) from the slot to be used.
