# Status indicator LEDs

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.

## LEDs on the end bracket

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.

## LEDs on the primary side of the board

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) | NS486 out of reset.
D33-35-37-39 | IPAC aux_6 (red) | User controlled.
D33-35-37-39 | IPAC aux_7 (green) | User controlled.
D34-36-38-40 | IPAC res (red) | ISDN framer set. Lit = Out of reset. Not lit = No problem.
