The CG 6565C board contains three types of LEDs:
The following illustration shows the CG 6565C LEDs:
The CG 6565C board provides two LEDs to indicate the status of each Ethernet interface as shown in the following table:
|
LED |
Description |
||||||||
|
SPEED |
Data rate of the Ethernet link.
This LED is used only when a reliable Ethernet connection is established. (The ACTIVITY LED is on.) |
||||||||
|
ACTIVITY |
There is activity on the Ethernet link. When the Ethernet establishes link integrity and there is transmit or receive activity on the link, the LED flickers on. |
The CG 6565C board has one green indicator (LED) for each trunk on the end bracket of the board. Only LEDs for available trunks are lit. The green LED indicates proper frame synchronization to the trunk: all required framing alignment has been found. This LED will be blinking if one or more of the following conditions exist:
All ones alarm ( AIS)
Loss of frame
Loss of signaling multiframe
CRC errors (when the board is configured for HDB3)
Red or yellow alarm
Note: When the board is not configured, all trunk indicators are turned off.
No trunk LEDs are illuminated if the NetworkInterface.T1E1[x].Type keyword is set to NONE.
The status LEDs indicate the state of the board. The following table describes the function of each LED:
|
LED label |
Description |
|
OK |
Illuminated green and blinking slowly: the board is functioning as expected. |
|
Standby |
Illuminated yellow during board initialization. When the board is successfully initialized, the LED turns off. |
|
Fault |
Illuminated red: an error condition exists. |
The Hot Swap LED (blue) illuminates when it is safe to remove the CG 6565C board from the system. The LED illuminates under one of the following conditions:
If the board is fully inserted when the backplane is powered-up, the blue LED momentarily flashes. This is a normal part of the initialization process.
After opening the handles (during the extraction process), the LED illuminates to indicate that it is safe to remove the board. Do not remove the board until the LED illuminates. This occurs only if Hot Swap software is present.
If the LED remains illuminated after insertion of a board and after you have closed the handles, the board failed to successfully perform its primary hardware initialization. While it is safe to remove the board, this condition indicates a problem.
The Hot Swap operation is defined in the CompactPCI Hot Swap Specification PICMG 2.1 R1.0.
Do not hot swap the rear I/O transition board while the CG 6565C board is powered up. You must power down the CG 6565C board to remove or replace the rear I/O transition board.
