Step 2
Remove the power cable from the power supply by doing the following:
• To remove an orange power cable connector from a 48-V DC power supply, do the following:
a.
Push the orange plastic button on the top of the connector block inward toward the power supply.
b.
Pull the connector block out of the power supply.
• To remove an Anderson Power Products Saf-D-Grid power cable connector from a high-voltage power supply, press
on the tab at the top of the Saf-D-Grid connector and pull the connector out of the power supply.
Step 3
Grasp the power supply handle while pressing the release latch towards the power supply handle.
Step 4
Pull the power supply out of the bay.
What to do next
You are ready to install a DC power supply in the open slot.
Installing an AC Power Supply
You can replace one power supply while the other one provides power to the switch.
Before you begin
• The power supply that you are installing must be capable of using the same airflow direction as the fan
trays installed in the same switch and it must use the same type of power source as the other power supply
installed in the same switch (do not mix AC and DC power supplies in the same switch).
DC power supplies with green coloring have the same port-side intake airflow
direction as the power supplies with red coloring, and DC power supplies with
gray coloring have the same port-side exhaust airflow direction as the power
supplies with blue coloring. If the power supply that you are replacing has a
different color handle than the replacement power supply, verify that it has or
will have the same airflow direction as the other modules in the switch.
Note
• An AC power source must be within reach of the power cable that will be used with the replacement
power supply. If you are using
n
+
n
power redundancy, there must be a separate power source for each
power supply installed in the chassis. Otherwise, only one power source is required.
• There must be an earth ground connection to the chassis that you are installing the replacement module.
Typically, the chassis is grounded by its metal-to-metal connection with a grounded rack. If you need to
ground the chassis, see
Grounding the Chassis, on page 21
Step 1
Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, turn
the power supply so that its release latch is on the right side and align the back end of the power supply (the end with the
electrical connections) to the open power supply slot before carefully sliding the power supply all the way into the slot
until it clicks into place.
