C. ATTACH TWO UNITS TOGETHER, IF NECESSARY
8.4 To create a dual-chassis system, connect two basic chassis together as follows:
NOTE: If necessary, an original chassis and a new-style chassis can be connected together to
create a dual-chassis system. If you are rack mounting the chassis or stacking them vertically,
instead of following these procedures, use the longer expansion cable (part no. 813.1636-1B) to
connect the chassis.
1.
On one equipment chassis, remove the two screws securing the small access panel on
the right side of the chassis and set the panel aside.
2. On the other chassis, remove the two screws securing the small access panel on the left
side of the chassis and set the panel aside.
3. With the cutouts to the middle, place the two chassis side by side.
4. Using the screws removed in steps 1 and 2, connect the two chassis together as shown
in Figure 3-38 on page 3-78. (The screws are inserted through the chassis on the left
into the chassis on the right.)
5. Remove the resistor from connector RN2 on the backplane in the second and fourth
chassis (right-hand, as viewed from the front) and attach it to connector RN5 on the
same backplane. (See Figure 3-39 on page 3-79.) In the left-hand chassis, the resistor
should remain in location RN2.
NOTE: In tri-chassis and quad-chassis installations, the location of the resistor in the
third chassis should match the location of the resistor in the first chassis. Similarly, the
location of the resistor in the fourth chassis should match the location of the resistor in
the second chassis.
6. Attach one end of the 60-pin chassis expansion cable (part no. 813.1576) to connector
J10 on the backplane in the left-hand chassis.
7. Route the free end of the equipment chassis expansion cable through the cutout into the
other equipment chassis and attach it to connector J9 on the backplane in the right-hand
chassis.
NOTE: An ATM system supports up to four single- or dual-chassis. It does not support tri- or
quad-chassis systems.
