HP RP3440 / 4440 MP console command to clear amber LED

Our RP3440s & 4440 which has redundant power inputs suffered from a single
side power trip over the weekend: servers did not reboot but one LED in the
front turned amber.

I tried googling but no joy.  How can I get into the MP (is the default login id
Admin/Admin  or  Oper/Oper) & what's the steps/commands to clear away
the LED without rebooting the server?

Would a Cisco light blue ribbon console cable (DB9 on one end & RJ45 on the othe
 end) allow me to connect from my old Dell laptop (which has a DB9 serial port)
to the MP console?

Well, I've been looking on the HP support site, I've found this but I don't have access. Maybe you have.

Ok, page 50 in link below:

So I just
<ENTER> till the end

Will the logs given by "SL" indicate if it's a power trip or humidity/temperature issues?

The manual doesn't say what the cause is, but I'm thinking it's the power trip, reading the log entries is supposed to clear the LED. You don't have access to the HP support site? I don't so can't help you there.

For newer Redhat Linux (RHEX 5.x) versions, would it log down in
/var/log/messages the loss of power redundancy?

What about Windows Event viewer?

Hello sunhux, I'm sorry, I don't know this. You could  use "Request Attention" for this question to have other experts look at your issue as well.
It has iLO
If it has any operator display you can use that to set ILO ip address and use password from cardboard label to log in as Administrator or root (i suspect they are equal)
Or notmally you can set up iLO from SMH and/or SMT too
