Updating iLO 3 firmware on HP servers

Once I set up iLO on servers and noticed that when opening an interface in the browser, an SSL error occurs and the iLO web interface does not open.

See how to temporarily solve this error in my article – Solution of the iLO error “HTTP SSL_ERROR_BAD_MAC_ALERT”.

For example, I will use HP ProLiant DL380 G7 with old firmware iLO 3 1.10 (Jul 26 2010)

HP LaserJet P2055dn Firmware Update

I noticed once that the HP LaserJet P2055dn printer began to print for a long time, there were long pauses between printing, while there were no problems with the network and the size of the printed files was small.

Going to the IP-address through the browser in the printer’s web interface in the menu “Status” – “Device Configuration” you can see the version of the current firmware (firmware), it should be older than the downloaded one.

Let’s download the new firmware from the official site
https://support.hp.com/us-en/drivers/selfservice/HP-LaserJet-P2000-Printer-series/3662052/model/3662058

Run the downloaded file, select the printer in the window that opens (it should be turned on) and click “Send Firmware” to start the firmware update process. Wait for the firmware update to complete.

This completes the update process. By the way, after the update, the problem with the delay in printing disappeared.

Reset HP A5800 Switch to Factory Default Configuration

On the test, I reset the configuration on the HP A5800 Series Switch JC103A.

And so, connect to the device and see what files are in the device’s memory:

dir

By default, the configuration is saved in the file config.cfg, let’s say that it is, so we’ll delete it:

delete config.cfg

We removed the configuration file, now we will reboot the device:

reboot

On the offer to keep the configuration we will refuse and on the next issue agree to the reboot:

This command will reboot the device. Current configuration will be lost, save current configuration? [Y/N]:n
This command will reboot the device. Continue? [Y/N]:y

Done, the switch will start with the default configuration, after which you can begin to configure, for example, as I described in the article – Настройка HP 5800

You can also try to reset the configuration as follows:

reset saved-configuration
reboot

Either through the Boot menu, to open it, when you turn on the device, press Ctrl+D and pressing the number 5, we select in the menu the reset of the configuration:

5. Restore to factory default configuration

Then, press 0 to select the reboot:

0. Reboot

When starting the switch, make sure that the configuration is reset:

display current-configuration
display saved-configuration

Solution of error “The transceiver type is not supported by port hardware” on HP A5800

I noticed once on the switch HP A5800 Series Switch JC103A, when inserting the module Foxgate SFP-1SM-1550nm-10SC (10km), the following error:

%Apr 26 12:18:56:384 2000 HP OPTMOD/4/MODULE_IN:
 GigabitEthernet1/0/24: The transceiver is UNKNOWN_SFP_PLUS.
%Apr 26 12:18:56:524 2000 HP OPTMOD/5/CHKSUM_ERR:
 GigabitEthernet1/0/24: The checksum of transceiver information is bad!
%Apr 26 12:18:56:674 2000 HP OPTMOD/3/TYPE_ERR:
 GigabitEthernet1/0/24: The transceiver type is not supported by port hardware!

Alternatively, you can try running the command:

transceiver phony-alarm-disable

But in my case this command did not help.
Also noticed that the error did not occur when inserting a similar module is not at 10km, but at 3km – Foxgate SFP-1SM-1550nm-3SC 3km.

The problem was solved by updating the firmware of the switch, as I did in the article – HP A5800 Firmware Upgrade
I updated the firmware from “A5800_5820X-CMW520-R1809P11” to “A5800_5820X-CMW520-R1810P13”.
After the upgrade, both modules were working and there were no errors in the console.
