THE FAN TRAY MODULE
The TLX48 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 along the
chassis side panel. This cools the horizontally mounted I/O
Cards, the Control 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 (adapter included) and an
external DIP Switch
for setting IP addresses.
The TLX48 Critical Hardware Alarm contacts are NC

Alarm Descriptions for the TLX48
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 Control Card(s) and on the I/O Card(s)
monitor continuously for any anomalous conditions.
THE INPUT / OUTPUT CARDS
TLX-MSD-M00016
TLX-MSD-C00016
The TLX48 10G contains up to 3 horizontally mounted I/O Cards.
I/O Cards provide the 1
st
(ingress)
& 3
rd
(egress) stages of a three stage Clos switch fabric.
The hot-swappable Input/Output (I/O) cards provide in-service expansion capabilities in sets of 16 ports
per I/O card, thus allowing re-configuration without interrupting signal processing.
Each I/O card consists of one Transmit (T) and one Receive (R) optic per port.
I/O Cards are available
with CATX or LC-type fiber connectors and can be assembled with Single-mode or Multi-mode
optics (SFP+).
Each individual I/O Card lists the ports as 1 through 16 on the TLX48. A blue LED located
on each I/O card indicates when power is applied to that card.
