INSTALLATION PROCEDURE
4. PROCEDURE FOR FANU IN THE FAN BOX
When any IMG is configured by 3 or 4 PIMs, the FANU must be accommodated within the FAN BOX in the center
of the cabinet. Because the FANU is originally mounted on the TOPU as shown in Figure 005-3, relocate the FANU
into the dedicated FAN BOX as per the STEPs below:
STEP 1: Referring to Figure 005-3, remove the FANU from the TOPU.
• Remove the two screws fastening the PZ-M369. Then, lift away the PZ-M369.
• Remove the four screws fastening the FAN Mounting Plate (tipped with three FANs).
• Then, lift away the FAN Mounting Plate.
Note: Retain the removed screws.
STEP 2: Fasten the PZ-M369 and FAN Mounting Plate onto the FAN BOX connection bar (refer to Figure
005-8). Use two screws (for PZ-M369) and four screws (for FAN Mounting Plate) retained in STEP
1.
STEP 3: Connect the FAN cables for “FC0,” “FC1” and “FC2” connectors on the PZ-M369. Refer to Figure
005-9.
STEP 4: Insert the FANU, prepared in STEP 1 through STEP 3, into the FAN BOX. Then, secure the FANU
with the two screws (refer to Figure 005-8).
