SPEX-HS Module Error

Hi; We stacked 2 ASN router with SPEX-HS module. I explained step by step at the below.

1. We upgraded prom and diagnostic images oft these 2 ASN routers.(it is required for stacking). Their prom version is the same now.

2.We replaced our SPEX-HS card into 4. slot of Router.

1. We set slot ID number for stacking routers. we set first router with 1 and second with 2.
2. Then we plug the cable to A on the SPEX-HS card.

5.After we put pcmcia flash card into router.(We put it in first router)

1. We boot it. When it is booting we got an error message like below.

Attention: SPEX-HS Failed Hardware Diagnostics.Not Attempting Boot.
