Removing an SFU
Step 5
Insert the new SFU into the chassis.
1.
Take out the new SFU from the ESD bag.
NOTICE
– Pull out the SFU slowly and smoothly to prevent it from hitting neighboring boards
and affecting running boards.
– Touching parts on the SFU when swapping it may damage the SFU.
2.
Support the lower edge of the new SFU with one hand and hold the panel with the other
hand. Then, insert the new SFU smoothly into the chassis along the guide rail of the slot,
as shown in
(1). Stop sliding the SFU forward when the ejector levers on the
front panel of the SFU reaches the chassis.
3.
Turn the ejector levers on the SFU outward and upward to form a 45-degree angle, and at
the same time push the SFU into the slot. Then, turn the ejector levers inward and
downward until the panel of the SFU touches the slot, as shown in
(2).
4.
Using a Phillips screwdriver, turn the two captive screws clockwise to tighten them, as
shown in
