Chapter 2. Base Station Components
2.2 5-Slot ATCA Chassis
The PM500 Base Station is based on a 5U high ATCA compliant modular chassis.
The chassis contains five physical slots numbered 1 through 5 that accommodate
three different Aperto hot-swappable cards:
Main System Controller (MSC)
Wireless System Controller (WSC-S-24)
Quad Wireless Controller (QWC) (holds up to four WSC-S-48’s)
Table 2-A lists and defines the slot positioning rules for the above-listed cards. Fully
populated slots for slots 3, 4 and 5 with three QWC cards, each containing four
WSC-S-48’s, defines the 12 sector system.
The PM5000 Base Station system assigns a logical port number for each WSC and
is based on this card’s physical slot location in the chassis. The logical port number
acts as the internal address for the card and is used in the CLI, SNMP, and EMS
management interfaces.
Table 2-B lists and defines the logical port number assignments for the WSC-S-48’s
(installed in a QWC).
