Description of CXPA and CXPB
CXPA and CXPB are dual-slot single boards, one CXPA or CXPB occupies slot1 and slot2 at the same time, and the functional characteristics of CXPA and CXPB are the same except for the difference in matching impedance.
Since ML1 and ML1A have the same functional characteristics except for the difference in matching impedance, the CXPA and CXPB have the same functional characteristics.
● All single boards except the power supply board support hot swapping.
● Maximum service switching capacity is 3G.

Description |
|
Operating Status Indicator STAT |
|
Lights up (green) |
Normal operation of the single board |
|
|
Bright (red light) |
Single-class hardware failure |
|
|
|
Bright (yellow) |
Indicates that the interface board or PIM single-shift board is powering up aging indication or not loading logic |
|
|
|
Out |
Indicates that the single class is not powered on or the single class has not been created or the single class is not in a power-up state |
|
|
Program Status Indicator PORG |
|
Lights up (green) |
Indicates that the upper layer software is initialized; or the software is running normally |
|
|
Lights up (red) |
Indicates memory self-test failure; or upper layer software loading is unsuccessful; or logic file is missing; or upper layer software is missing |
|
|
|
Lights up for 100 milliseconds and goes out for 100 milliseconds (green light) |
Write FLASH operation or software loading is in progress; |
|
|
|
300 milliseconds on 300 milliseconds off (green light) |
Is in the BIOS boot stage (during power-up/reset) |
|
|
|
100 milliseconds on 100 milliseconds off (red light) |
BOOTROM self-test failure; or logic loading failure |
There are 2 optical ports not visible on the panel diagram, which are integrated on the main control board for interfacing between PTN devices.
For PTN910, the 2 port indicators integrated on the main control board are: L/A1, L/A2
The first situation: L/A1 are not lit, indicating that this end can not receive the opposite end of the light, the reason for analysis, fiber optic cable breaks, or the opposite end of the power outage.
The second situation: L/A1 green and yellow flashing back and forth, indicating that there is no problem with the optical path.
