Replacing a power supply
To replace a power supply, you need the following:
• A new power supply (AC or DC), which you can order from Brocade
• A small flathead or Phillips screwdriver (BigIron RX-4 only)
DANGER
The power supplies are hot swappable, which means they can be removed and replaced while
the BigIron RX Series chassis is powered on and running. However, Brocade recommends that
you disconnect the power supply from its power source before removing and replacing the
supply. The BigIron RX Series chassis can be running while a power supply is being removed and
replaced, but the power supply itself should not be connected to a power source. Otherwise, you
could be injured or the power supply or other parts of the device could be damaged.
DANGER
The front panel of an power supplies include a handle that locks the power supply in the chassis.
This handle is a locking mechanism only and should not be used to lift and carry the power
supply. You may sustain physical injury or harm if you attempt to lift and carry a power supply
using the locking handle.
Follow the steps given below to replace a power supply.
1. Disconnect the power supply from its power source.
2. Disconnect the power cables from the power supply.
3. In the BigIron RX-4 use the screwdriver to loosen the two screws on both sides of the power
supply front panel. Then pull the ejectors forward until the power supply is pulled from its
connection to the backplane.
4. In the BigIron RX-8, BigIron RX-16, pull up on the plunger in front of the faceplate and pull on
the handle toward you until the power supply is released.
5. Continue to pull the power supply until it is removed from the chassis.
6. Insert the new power supply into the empty power supply slot, using the guides provided on
either side of the slot.
CAUTION
Carefully follow the mechanical guides on each side of the power supply slot and make sure the
power supply is properly inserted in the guides. Never insert the power supply upside down.
7. After the power supply is fully inserted, push the power supply front panel toward the back of
the chassis until the power supply is fully seated.
8. In the BigIron RX-4, use the screwdriver to secure the two screws on either side of the power
supply front panel.
9. Connect the AC power cord or DC power lugs to the power supply front panel.
