Attach Two Units Together, if Necessary
C. ATTACH TWO UNITS TOGETHER, IF NECESSARY
9.4 To create a dual-chassis system, connect two basic chassis together as follows:
NOTE: If necessary, an original equipment 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) 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 equipment 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 3-42 on page 3-87. (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 right-hand chassis (as
viewed from the front) and attach it to connector RN5 on the same backplane. (See Fig-
ure 3-43 on page 3-88.) 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 [C99 in
Europe] to connector J10 on the backplane in the left-hand chassis.
7. Route the free end of the chassis expansion cable through the cutout into the other chas-
sis 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.
D. ATTACH THREE OR FOUR UNITS TOGETHER, IF NECESSARY
9.5 To create a tri-chassis system, simply connect one dual-chassis system to a single-chas-
sis system using a fiber-optic cable between the two PCM-F cards. To create a quad-chassis
system, simply connect two dual-chassis systems together using a fiber-optic cable between the
two PCM-F cards. (See page 2-12 for additional/other multiple-chassis system configuration
information, and see page 3-104 for the actual fiber-optic connection instructions.) If neces-
sary, the fiber-optic cable between the first (master) chassis and the third (slave) chassis can be
up to one kilometer (.6 miles) in length. If running version 8.0 or later, you must use a CP
Server for tri-/quad-chassis systems.
NOTE: A 8.5-foot (2.5 m) cable is available using part no. 813.1628 [C118 in Europe]. Or, if
necessary, contact Inter-Tel's CommSource division or Inter-Tel Europe for information on pur-
chasing longer cable lengths. Custom cables can also be built using industry-standard ST-type
connectors.
