T1100 AS Hardware Feature Information
• Peripheral Component Interconnect (PCI) cards
• PCI express card
• Power Supply Modules
• Complete T1100 AS Chassis
• LEDs to indicate which drive needs attention in case of drive failure
The fans, filters, power modules, 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 behind the front fascia (for more information,
see "Fans, Fan Assemblies, and Air Filters" on page A-5). The disk drives are
accessible from the front of the unit (for more information, see "Component
Access front fascia" on page A-5). The PCI cards are located at the rear of the
T1100 AS chassis and plug into the main board.
All other components, which are less likely to fail, are located in the Tekelec 1100
AS 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) 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 T1100 AS
chassis before switching OFF all circuit breakers or power distribution units
supplying redundant power. For more information about troubleshooting
systems and performing soft shutdowns, see the appropriate maintenance
manual for the application.
Component Access front fascia
The Tekelec 1100 AS platform has a hinged front fascia that is locked in place by
captive screws during normal operation. This lid allows access to the fan
assemblies and hard drives. The front lid also has the following features:
• Light emitting diode (LED) alarm indicators, mounted to the front surface of
the lid.
• LED indicators to indicate which drive to replace in case of failure.
Fans, Fan Assemblies, and Air Filters
The Tekelec 1100 AS platform has three fan assemblies to provide a redundant air
source. This enables the system to run with a single fan failure and allows for
replacement of a fan assembly while the Tekelec 1100 AS platform is operational.
The fan assembles are mounted in the Tekelec 1100 AS chassis to enable easy
replacement.
The fans have a tachometer output that is monitored by the platform software. If a
fan fails, the platform software generates an alarm. All Tekelec 1100 AS internal
cables are routed for minimal impact to airflow.
