POWER SUPPLY MODULES
The dual, redundant power supplies ensure continuous,
uninterrupted power.
The supplies are current sharing which
means the supplies share the load equally. If a power supply
fails, the redundant power supply can support the entire current
load of one fully populated card cage.
Although the TLX320 functions properly with one Power
Module,
Thinklogical recommends that both modules be
used, preferably connected to independent power sources,
for redundancy
.
Each Power Supply module contains an internal cooling fan.
Additionally, the hot-swappable feature allows easy replacement of a module without interrupting the
TLX320
’s system functionality.
THE FAN TRAY MODULE
The TLX320 uses 3 DC fans located in one modular, hot-
swappable fan tray designed for easy replacement without
interrupting system functionality.
The Fan Tray introduces air
into the chassis through air baffles within the chassis. This cools
the vertically mounted I/O Cards, the Controller Cards and the
backplane.
The Fan Tray is also equipped with an
annunciator port
for
system alarms which can be configured to trigger an external
control system and an
external DIP Switch
for setting IP
addresses.
ALARMS:
The Fan Tray is equipped with an annunciator port for system alarms that can be configured
to trigger an external control system. The dry alarm contacts are
Normally Closed
when unpowered,
Normally Open
when powered (OK condition) and
Closed
for an alarm condition.
Maximum switching capacity is 2A at 12V.
Alarm Descriptions for the TLX320
All fan speeds are monitored. Any fan speed that does not meet specification will cause an alarm
condition.
The temperature in the chassis is monitored by internal temperature sensors in several locations.
Sensors located in the Power Supply(s), Fan Tray, on the Controller Card(s) and on the I/O Card(s)
monitor continuously for any anomalous conditions.
