Resetting AP9618 Network Management Card

Hi all,

I have inherited a couple of Smart UPS RT 3000 (I think - one's branded Dell and the other is unbranded) with AP9618 Network Management Cards (NMC) attached that were set up previously but is no record of username passwords (not apc/apc), IP addresses or MAC addresses and have uninstalled the PowerChute software as I can't get into it.  I have found the MAC addresses and the IP's but cannot get the IP Configuration wizard to find them - I guess because they are already configured.

I have tried arp and ping to reset one of the cards to a different IP address on a VLAN tagged port on our switch, but cannot telnet onto the card to set it up. Running arp -a shows the MAC address with the IP address I set up with arp.

I have a couple of questions:

1. Will resetting the NMC affect the UPS i.e. turn it off and disrupt power to my production servers?
2. I have read that I can attach a cable  (940-0024C) and access it through the local console. The cable I have has 2 D-SUB connectors, but cannot find a corresponding port on the NMC only one on the UPS itself. Where should I attach the cable to on the NMC?

Thanks
Tony

Resetting the NMC will not disrupt output.

You attach the 940-0024C cable to the serial port on the UPS. Using a terminal emulator (hyperterm, putty) the settings should be 2400bps, no parity, 8 data bits, 1 stop bit, and no flow control.

We have Kbase FA156075 "Network Management Card (NMC) Password Reset Procedure" that should help.

Thanks Bill, I'll give that a try.
