Mechanical Design
The Tekelec 1000 mechanical design meets all applicable NEBS requirements and
is designed to protect all of the active components. The design has efficient
component cooling using low-impedance air paths, and its compact size allows
multiple units to be configured in a frame with zero top and bottom clearance
when stacked.
Mechanical Maintenance Features
The Tekelec 1000 hardware has been designed for easy maintenance. The
following components are field-replaceable units (FRUs):
• Fans
• Fan filters
• Disk drives (located on the removable lid)
• CD/DVD drive assemblies (located on the removable lid)
• Peripheral Component Interconnect (PCI) cards
• Complete T1000 AS Chassis
The fans, filters, and disk drives have lower mean time between failures (MTBF)
and can be easily replaced, so they have been grouped together. The fans and fan
filters are grouped in the front panel (for more information, see "Fans, Fan Trays,
and Air Filters" on page A-5). The disk drives are located in the removable lid (for
more information, see "Component Access Front Lid" on page A-5). The PCI
cards are located at the rear of the T1000 AS chassis and plug into the main board.
All other components, which are less likely to fail and are more difficult to
replace, are located in the Tekelec 1000 main unit. If one of the components in the
main unit fails, the hard disk drive assemblies (preserving the data which is
stored on the hard disk drives in the lid) can be removed from the failed chassis
and installed in the replacement chassis.
NOTE: Use the procedures in Chapter 7, "Field Replaceable Units" when
removing or replacing FRUs. Always perform a soft shutdown of the T1000 AS
chassis before switching OFF both circuit breakers supplying redundant
power. For more information about troubleshooting systems and performing
soft shutdowns, see the appropriate maintenance manual for the application.
