v If you are removing a memory riser card (M02 or M05) or the DIMMs in a Model 830/SB2 system
unit, go to step 7 (See page 55).
v If you are removing the Network Interface Controller (NIC) card (M06) or the clock card (M06A)
from the NIC Controller card on a Model 830/SB2 system unit, go to step 8 (See page 55).
v Otherwise, you are removing a processor card assembly (M03 or M04) in a Model 830/SB2 system
unit. Go to step 9 (See page 56).
6. You are removing a processor regulator card in a Model 830/SB2 system unit (processor drawer).
Perform the following:
a. On the opposite ends of the card, press the two latch surfaces together to release each latch.
b. Pull on both latches at the same time to remove the card from the slot.
c. Rotate the latches upward.
d. Install the new card by reversing the removal procedure. After exchanging an item, go to "Verify

This ends the procedure.
7. You are removing a memory riser card (M02 or M05) or the DIMMs in a Model 830/SB2 system unit.
Perform the following:
a. On the opposite ends of the memory riser card, press the two latch surfaces together to release
each latch.
b. Pull on both latches at the same time to remove the card from the slot.
c. Rotate the latches upward and remove the memory riser card.
d. If you are replacing the riser card, then you must move the memory DIMMs to the new card. See
Figure 3. CCIN 2881 with pluggable DIMM (See page 267) in the Locations — Model 830 topic,
for DIMM locations.
e. If you are adding or replacing memory DIMMS, refer to the Figure 3. CCIN 2881 with pluggable
DIMM (See page 267)in the Locations — Model 830 topic, for DIMM locations.
f. Unlatch the DIMMs from the memory riser card by pressing down on the latches that are on
opposite ends of the DIMM.
g. Firmly press the DIMMs on to the memory riser card until fully seated.
h. Complete the repair by reversing the removal procedures.
i. After exchanging an item, go to Verify the repair.
This ends the procedure.
8. You are removing the Network Interface Controller (NIC) card (M06) or the clock card (M06A) from
the NIC controller card on a Model 830/SB2 system unit. Perform the following:
a. Remove the mounting screws from the EMC tunnel that is attached to the processor drawer.
b. Remove the EMC tunnel from the processor drawer.
c. On the opposite ends of the controller card, press the two latch surfaces together to release each
latch.
d. Rotate the latches upward.
e. Pull up on both latches at the same time to remove the Network Interface Controller card.
Note: If you replace the Network Interface Controller card, then you need to remove the clock
card and install it on the new controller card.
f. Locate the small plastic cover on the side of the Network Interface Controller card. Press the two
locking tabs together and remove the cover.
g. Hold the controller card with the opening facing up, then grasp the bar handle on the clock card
and pull straight up to remove it.
h. Align the holes in the clock card with the guide pins on the controller card. Press down firmly on
