2.1 INSTALLATION AND SAFETY (ENGLISH TEXT)
The unit is designed to offer operators reliability and flexibility. It consists of a chassis in which a number of modules
can be installed. To cater to specific system requirements, the chassis can be configured to host functional modules
best suited for a given scenario.
Appear products can be delivered in different chassis variations - 1RU chassis and a 4RU chassis. The product models
DC1000/1001, SC2000/2001, MC3000/3001 and XC5000 represents the 4RU chassis, while the product models
DC1100/1101, SC2100/2101, MC3100/3101 and XC5100 represents 1RU chassis.
2.1.1 THE 4RU CHASSIS
The 4RU chassis consists of a total of 18 slots all of which can host functional modules. Slot number 0 is dedicated to
host the switch module and slot number 17 can only host multi-slot input modules. Alternatively a second switch
module can be placed in slot 17 for some redundancy configurations. The remaining 16 slots are identical and can be
occupied by any of the functional modules available. A 4RU chassis including a mandatory switch module, power
supply connectors, and module slots is shown in Figure 2.1 and 2.2. Power modules and fan modules are inserted from
the back (figure 2.3 showing the XC5000).
