The AG 2000-BRI board has two banks of indicators (LEDs) on the end bracket of the board and 30 indicators (LEDs) on the primary side of the board.
The following illustration shows the two rows of LED indicators on the end bracket of the AG 2000-BRI board:
LEDs on the end bracket
The board locate indicator identifies the board using the software. The status indicator remains on after the board is booted.
The location of the LEDs on the primary side of the AG 2000-BRI board is shown in the following illustration:
LEDs on the primary side of the AG 2000-BRI board
The following table describes the LEDs on the primary side of the AG 2000-BRI board:
|
LED |
Purpose |
Description |
|---|---|---|
|
D1 - D4 |
DSPx_RST (4 Red LEDs) DSPx_XF (4 Green LEDs) |
The corresponding DSP is communicating with the NS486. Red = Problem Green = No problem |
|
D5 |
HMIC (green) |
Lit = No problem with the HMIC. Not lit = Problem with the HMIC. |
|
D5 |
CLK (red) |
Lit = No problem with the clock section of the HMIC. Not lit = Problem with the clock section of the HMIC. |
|
D6 |
OWN (green) |
Owner of SRAM. Lit = Idle of host. Not lit = Coprocessor. |
|
D6 |
TD (red) |
Transfer direction bit. Lit = Host access to SRAM. Not lit = 486 access to SRAM. |
|
D7 |
BUSY (green) |
Lit = SRAM is idle. Not lit = SRAM is in use. |
|
D7 |
76GO (red) |
