Installing Power Supplies in a NetIron MLX-4 Chassis
The NetIron MLX-4 accommodates three power supplies (AC or DC) with one required and two redundant. It is
shipped with one power supply. You must purchase one or two additional power supplies if you want your NetIron
MLX-4 equipped for redundancy. You need a small Phillips or flat-head screwdriver to perform this task.
To install a power supply in the NetIron MLX-4 chassis, do the following:
1.
Remove the blank power supply faceplate, and expose the empty power supply slot.
2.
Remove the power supply from its packaging.
3.
Insert the power supply into the empty power supply slot, using the guides provided on either side of the slot
and slide the card along the card guide until the ejectors on either side of the module move close to the
module front panel.
NOTE:
Empty power supply slots should be covered with slot blanks.
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.

4.
After the power supply is fully inserted, push the power supply front panel toward the back of the chassis. This
action causes the power supply connector to seat into the backplane connector.
5.
Push the ejectors in until they are flush with the face of the power supply. This action will fully latch the power
supply in the backplane.
6.
Tighten the two screws at either end of the power supply front panel by pushing them in and turning them
clockwise. If desired, tighten the screws further using the flat-head screwdriver.
7.
For information about connecting power to the chassis, see “Connecting AC Power to a NetIron MLX-4
Chassis” on page 3-9 or “Connecting DC Power to a NetIron MLX-4 Chassis” on page 3-10.
Connecting AC Power to a NetIron MLX-4 Chassis
AC power is supplied through an AC power cord that is installed at the rear of the NetIron MLX-4 chassis.
NOTE:
For the NEBS compliant installation, AC power connections shall use a SPD (surge protection device) in
order to protect the AC power supplies from damage to excessive power line surges.
1.
At the rear of the NetIron MLX-4 chassis locate the power receptacle on the left side of the AC power supply.
2.
Lift the cord-retainer and connect a Foundry-supplied AC power cord to the power supply.
3.
Snap the cord-retainer over the power plug to hold it in place.
