sions 8.0 and later require a CP Server for tri- and quad-chassis systems. This means that the
first chassis must have an EAC so that it can connect to the CP Server.

eight-slot circuit cardfile assembly. However, unlike the first and third chassis, the fourth chas-
sis does not require its own CPU020/PCM card. The first and second chassis (master dual-
chassis) are connected to the third and fourth chassis (slave dual-chassis) through a special
fiber-optic cable.

connected together to form an eight-chassis node (see
system). Like the dual chassis, each second chassis has its own power supply unit and eight-
slot circuit cardfile assembly. Each chassis pair also has its own CPU020/PCMA card, which is
connected to the ATM Switch through a CAT5 or multi-mode fiber (MMF) cable. Because
each pair is independently connected to the ATM Switch, there is no master-slave relationship
like there is in a quad-chassis system.
Multiple-Chassis Configurations

poses, multiple-chassis configurations are always numbered as shown below – even though the
master section may have only one actual chassis installed. (Chassis can be rack mounted

exists) should be located in the master dual-chassis. The first (master) and third (slave) chassis
in all tri-/quad-chassis installations must be equipped with 9 amp power supplies. The PCM-F
card or PCM-F/EAC requires a 9 amp power supply. Also, if the two portions of a tri-/quad-chas-
sis system are installed on the same vertical plane on the same MDF, the first pair of chassis
(master dual-chassis) must be separated from the second pair of chassis (slave dual-chassis)
by at least one foot to provide proper air circulation. In addition, tri-/quad-chassis systems
require a CP Server to run software version 8.0 or later.
