Figure 2. EXM Slot Numbering.
Figure 2 lists two sample EXM slot configurations, but there are several chassis
options available. Consult the specification sheet that shipped with your chassis if
you are unsure about slot numbering for your particular system.
All slots
not
occupied by an EXM module should show an ID of FF and OB1/OB2 of
00 00 indicating that no EXM is present.
To add or change an EXM configuration, use the cursor keys (arrows) to move
between the fields on the screen. Move the cursor to the appropriate slot entry and
type in the correct value.
The
ID
for the EXM-31 should be set to
D0
h (D-zero).
OB1
is a hexadecimal value derived by combining the following:
Reserved
(bits 7-4)
INT Select
(bits 3,2,1)
Card Enable
(bit 0)
