    Circuit Card Installation Into New CPR
    This procedure shows how to install the new CPR into the LPM.
    (1) Detach the front panel of the new CPR by using the Phillips screwdriver to remove
    the four screws, as shown in Figure 4-4. Then, lift the top cover by removing the
    eight screws.

    (2) Insert the ISAGT (PZ-GT13/PZ-GT20) and LANI (PZ-PC19) cards into the
    following slots of the new CPR (refer to Figure 4-5):
    ISAGT (PZ-GT13) →Slot 6 (ISA)
    ISAGT (PZ-GT20) →Slot 5 (ISA) (When LN has more than two IMGs) 
    Note
    LANI (PZ-PC19) →Slot 0 (PCI) (For Fusion Link)
    LANI (PZ-PC19) →Slot 1 (PCI) (When connecting MAT via 10-BASE T and PCI buses)
    LANI (PZ-PC19) →Slot 3 (PCI) (When LANI for Fusion Link is in dual configuration)
    Figure 4-5 shows how to insert the ISAGT and LANI cards into the PCI slots 5 and 6, 0 and 1 and 3 of the
    CPR, respectively.
    Note:This card is mounted in LN only.
