SX-200 ELx Cabinet
The SX-200 EL and the SX-200 ML system use the same rack mount (RM) horizontal cabinet,
the SX-200 ELx cabinet (PN 9109-600-002-NA), for the control cabinet and for the peripheral
cabinet.
The horizontal cabinet can be mounted in a standard 19" rack, or they can be stacked. The
cabinet is plastic and plexiglass. The door on the cabinet allows the system administrator to
see the system status at a glance. The control cabinet and the peripheral bays are linked by
fibre or copper cables.
Located on the rear of the SX-200 ELx cabinet are four 25 pin connectors (J1- J4 for the
peripheral interface cards), three RJ-45 connectors (J5 and J6 for T1 trunks and J7 for a system
fail transfer control port), a printer port, a grounding connector, a maintenance port, and two
RS-232 connectors (J10 and J11 for the PRI maintenance).
The SX-200 ELx cabinet supports 12 card slots: eight slots support line and trunk cards, and
four support the control cards and the FIM or CIM carrier cards. The cabinet can be configured
as the control cabinet or as a peripheral cabinet. The SX-200 EL system using a MCCIIIELx
card requires the SX-200 ELx cabinet in order to accommodate the three links to each cabinet.
The system requires an SX-200 ELx cabinet to support any of the following cards or functionality:
• BCC III card
• PRI card
• BRI card
• CLASS functionality of the ONS/CLASS Line card
• SX-200 IP Node
