Power led in asa5520 does not glow when powered, but others glow well. no console port response. It seems eqipment is working but not.

LG TV 3 blink code is due to bad power supply or LED lamps in the panel. If you have technical skills of soldering, physically check and replace if you found bulging capacitors in the power supply. If PSU is working, check LED back light strips with LED tester and replace faulty LED back light strip.

ALARM LIGHT which always glows - RAM error (logic board is dead)

Faulty led of the switch generally glows when the hardware latched to it goes faulty such as fans and power supply. please check for LED in any of these. if you won.t find any LED in red in any of these then try to connect your switch through console port of the switch, if the out is coming as garbage value ie it is not asking for username and password the try to power off the switch ( your live services will go down running through that switch, so plan a MW for that) .

Try to reset the configuration of your router from the reset button and try that you getting the console with its default username and password.

Seems that the battery is low on power, when the controller is connected to the usb port of the ps3, all leds should start flashing, this show that the battery of the controller is recharging, when done the leds go off.
Note that before the leds start flashing that it can thake up an minute before it starts doing that.
Keep your ps3 on to recharge the controller.

Succes.

possible solution;
1-turn off and turn back on
2-open the cover and check the power supply and LED

Check the outlet where u plug in the rice cooker. It could be that the circuit breaker has kicked off or the fuse has blown. let me know how you make out. If that isnt the problem I have additional suggestioins

yellow light on ports means the port is not working or was shutdown due to port security

so is the KVM (control side, PS2 mouse / kbd>??)
or are all PS2 ports wired to adaptors,? i cant guess this nor what was used before, no history stated.
what was there before, this act?
and what now?
Ill assume worse cases (tossed a coin)
18 (16+2) adapters now. all devices are USB but KVM
ok.?


what mode fails, both the KVM pushbotton switch and or the hot key commands on the kbd?
Oops no manual button as seen on modern KVM.

KVMs are very complex. the hard part is the vast number of different PC.
USB , PS2, VGA, DVI and HDMI.. yah,..
OK 16 +2=18 x ps2, and 9 VGA ports. it is.
NO KVM does it all, ,, old KVM' do NOT work , on new computers, all folks know this , if they tried. or took readings to learn why it fails.
I bet power to the KVM is dead., no LED./
no manual button ,oops.
pin 4 PS2 reads 5vdc and connected up, same?
we use breakout boxes (DIY) to test ports connected.'

that Compaq is very old and no support now, no books.
why not ask at real HP, maybe some old guy there can dig it lost books>
40 KVM? that what you said, really? (or 40/8=5 kvm)?
my guess is the adaptor does not work or power issues
KVM >>PS2>>>ADapt>>> USB.(server) (usb 1,2,or 3 at server?)
The KVM in most cases, here, steals power from PS2 ports but not this KVM , its better.
i'd bet that adaptor cant do that.
(is the caps lock key working on the KBD and laser LED glowing on said mouse?

ask here, real HP.
lets see tests:
1: pin 4 ps2 5vdc?
2: mouse glows?
3: keyboard led , caps lock toggles? (glows)
4: lost the hot key commands (y/n)

one other problem is the BIOS in the server may not like your adaptor at all. When BIOS scans the keyboard. it expects a ID response if missing or grabled, it drops that device port.

btw, one way to cure this, is run headless server software
end KVM for ever.

i run a LAMP server, that comes in the box, no kvm no any thing on ports. it has a web page to go to and do service that way.
port IP+:12321
modern ways work best.
in a server farm, a keyboard/mouse/monitor on rolling cart
for the super sick servers is best...

the other problem is USB only PC or server
does not scan PS2 ports, it has none
so if the adaption fails, at boot time, all is lost.
(BIOS reports connected devices to the OS)(unstated by you)so if the report fails, problems happen
for sure after the boot.

this device is s business device, now ("Enterprise)
the posts on it are like 10 years ago. all links to books now dead.
infact the compaq server that had them is turned off. (grin)
here is my search there. Why not ask them?
