The Network Interfaces
A TLX48 2RU uses up to three IP addresses.
The Primary Control Card uses address X and address
X+100. The Back-up Control Card uses address X+1 and will take over address X in the event of a failure
in the Primary Control Card. These addresses are set by an external DIP switch. See
TLX48 2RU DIP
Switch Settings
, pg.
.
The primary’s IP address can be set from 15 to 45.
The default subnet used
by the TLX48 2RU is 192.168.13.xxx.
The user may use their own subnet by reconfiguring the switch
’s
network startup.
This procedure is detailed in
:
Manual_How_To_Change_A_TLX_Matrix_Switch’s_IP_Address
The TLX48 2RU uses several network ports for control and status. Port 17567 accepts commands to
control the switch.
The command API is described in the document
:
Manual_TLX_Matrix_Switch_ASCII_API_V5
There are other ports that can be read to access system configuration and operating data. The actual data
format varies by model and is described in the following sections. There are five blocks of data available
for reading.
These ports are documented in:
Manual_TLX_Matrix_Switch_Interfaces
1.
Switch connection status
(broadcast over port 17564 every few seconds)
•
The primary CPU IP address
•
Upper or Lower chassis flag
•
First port number in this block
•
Last port number in this block
•
'N' port number values
2.
Port settings
(UDP port 17565, TLX48 2RU localhost only)
•
Port output level value
•
Port input enable status
•
Input port number (big-endian format)
3.
Hardware sensor status
(TCP port 17566)
•
Reserved for future use.
4.
Alarm, Inventory and Power Supply Status
(TCP port 17600)
•
State of the alarm contacts
•
Card Inventory
•
Power Supply Status (internal TL use only)
•
Switch card temperature readings
5.
I/O Card data
(TCP ports 17601 through 17640, 1 port per I/O card)
SFP installed bits
I/O card type
SFP TxDisable bits
I/O card temperature
SFP TxFault bits
SFP serial ID data
SFP LOS bits
SFP Diagnostic data
6.
Service Request (LOS) Signaling
(UDP port 17560)
The TLX48 2RU can broadcast a message over the network when a remote receiver requests attention.
When enabled, the receiver will toggle its TX pin, causing a LOS (loss of signal) event to occur at the
Switch. When detected, the Switch broadcasts an 'Attention Request' message over the network. This
message contains the IP address of the TLX48 2RU and the port number that detected the request. It is
left up to an external system to detect, decode and act upon this request.
•
32-bits, TLX48 2RU's primary IP address
•
16-bits, 0 for the Upper (or only) Switch chassis, 1 for the Lower Switch chassis (in some models)
•
16-bits, port number (list starts from 1, not 0)
•
16-bits, key code in bits 0
–
7, 0x00 and 0xff are ignored
