AT-2900 Series Gigabit Ethernet Network Adapters Installation Guide

C5. VPD Test

Function: It saves the content of VPD first before perform the test. Once it is done, it writes one of the five pattern test data, 0xFF, 0xAA, 0x55, increment data, or decrement data, into VPD memory. By default, increment data pattern is used. It writes and reads back the data for the entire test range, and then restores the original content.

Default: Disabled

C6. ASF Test

Function: m

1.Reset test.

Setting reset bit, poll for self-clearing. Verify reset value of registers.

2.Event Mapping Test

Setting SMB_ATTN bit. By changing ASF_ATTN LOC bits, verify the mapping bits in TX_CPU or RX_CPU event bits.

3.Counter Test

Clear WG_TO, HB_TO, PA_TO, PL_TO, RT_TO bits by setting those bits. Make sure the bits clear.

Clear Timestamp Counter. Writing a value 1 into each PL, PA, HB, WG, RT counters. Set TSC_EN bit.

Poll each PA_TO bit and count up to 50 times. Check if PL_TO gets set at the end of 50 times. Continue to count up to 200 times. Check if all other TO bits are set and verify Timestamp Counter is incremented.

C7. ROM Expansion Test

Function: This function tests the ability to enable/disable/access the expansion ROM on the device.

D1. Mac Loopback Test

Function: This is internal loopback data transmit/receive test. It initializes the MAC into internal loopback mode and transmits 100 packets. The data should be routed back to the receive channel and received by the receive routine which verifies the integrity of data. One Gigabit rate is used for this test.

Default: Enabled

D2. Phy Loopback Test
