My Arris 1500 came with upstream cards in slot 1 and 2. The channel 2 does not pass data or have the front panel light lit for 2. Manual says to add cards in the following order 1, 8, 2, 3.... So I've moved the card to slot 8. I can change admin-status to "up" for slot 8 but cable-level shows 8 to be down.
I'm accessing the 1500 remotely with putty and then telnet into the CMTS. What step I'm I missing??
Thanks - Rob
Rob - Have you tried switching upstream cards to see if the issue follows a specific card?
