Component Access Front Lid
The Tekelec 1000 platform has a hinged lid at the front that is locked in place by
captive screws during normal operation. This lid allows access to the fan trays,
BIOS select switch, reset button, and two USB ports that are located under the lid.
The front lid also has the following features:
• Light emitting diode (LED) alarm indicators, mounted to the front surface of
the lid.
• Space for routing and strain relief of cables to the media device, LED's, and
fan trays.
• Constant torque hinges, which are a safety feature to protect the attached
components from shock by preventing sudden closure of the lid.
• The following devices, mounted to the bottom side:
— Two 3.5 disk drives (HDD) mounted separately. Each HDD is mounted to
a bracket. This assembly is then mounted to the front lid.
— Two slimline drives (for removable media devices) and drive adapter
board, mounted together with a dual CD-RW/DVD ROM bracket. These
assemblies are then mounted to the front lid.
For both these assemblies, non-conducting stand-offs are used to isolate
the assembly from the lid to maintain isolation between chassis ground
and logic ground. The metal parts of the media devices are at logic ground
due to the construction methods.
Fans, Fan Trays, and Air Filters
The Tekelec 1000 platform has two fan trays to provide a redundant air source.
This enables the system to run with a single fan failure and allows for replacement
of a fan tray while the Tekelec 1000 platform is operational. The fan trays are
mounted in the Tekelec 1000 platform with captive hardware.
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 1000 internal
cables are routed for minimal impact to airflow.
The fan tray front support provides the mounting locations for the fan tray and
provides mounting for guides that facilitate the insertion and removal of the fan
trays. The fan tray front support also is part of the retaining component for the air
filter and provides finger protection from the spinning fan blades during air filter
replacement.
The front fascia attaches to the front of the Tekelec 1000 platform with four ¼ turn
fasteners. It is the air inlet cover and also serves to retain the air filter. The fascia
can be removed for air filter replacement while the drive is still mounted in the
frame. Finger guards between the filter and the fan assemblies located behind it
allow removal of the filter while the T1000 AS chassis is in operation.
