The redundant control node consists of the following components:
• Control Cards: The control node contains two Main Controller cards, two Circuit Switch
Matrix cards, a Mass Storage Expander (MSX) card, and a Control Resource card (CRC).
• Remote Storage Device (RSD) drive: An ISO-standard, 3.5 inch, magneto-optical disk
drive is mounted just below the hard disk drive on the front of the cabinet.
• Control Panel: The control panel, located on the right side of the front panel below the
hard disk, provides system controls and indicators. The control panel is not visible unless
the front panel of the cabinet is removed.
• Cabinet Frame: The redundant control cabinet is separated into three shelves. Shelf 1
and Shelf 2 are located at the front of the cabinet and hold the redundant power modules
and control cards. Shelf 3, at the back of the cabinet, holds the FIMs.
• Two Redundant Power Modules: Each redundant power module provides power from
one of the power supplies to the MSX card, the CRC card, the FIMs, and the RSD drive.
• Two Power Supplies: 200 Watt AC or 150 Watt DC power supplies provide redundant
power for the cabinet. The power supply fans cool the cabinet.
• Two Hard Disk Drives: The 3.5 inch wide x 1 inch high SCSI hard disks are mounted
side-by-side at the top of the cabinet. The hard disk drives are visible through openings
in the front cover.
• Fiber Interface Modules (FIMs): The control node holds up to 11 Fiber Interface Modules.
• Quad Fiber Interface Module (FIM) Carrier: Up to three 5 inch wide x 4.5 inch high (12.7
cm x 11.4 cm) Quad FIM Carriers can be set in the rear panel. Each Quad FIM Carrier
holds a Quad FIM Carrier card and up to four Fiber Interface Modules (FIMs). The FIMs
in a Quad FIM Carrier connect to the control backplane through two ribbon cables. There
are four standoffs on the rear panel; two installed above the Quad FIM Carrier cards and
