Some vendors may use custom protocol elements and TLS encryption, that does not have available documentation. For this reason, these cannot be audited by SPS. Independetly from the vendors, only those custom features are supported that are described in the RFC 6143. Regarding encryption, only the completely TLS-encapsulated streams can be processed where the TLS encryption process was started before the VNC protocol handshake.
It may happen that you inadvertently lose the IPMI pasword of your SPS. In that case, you will be required to:
Shut down SPS.
Unplug the SPS physical appliance's power cord.
Wait 30 seconds.
Replug the power cord.
Restart the appliance.
Re-configure the IPMI interface from the BIOS.
To confgure IPMI from the BIOS, complete the following steps.
To apply the procedure outlined here, you will need physical access to a monitor and keyboard.
Press the DEL button when the POST screen comes up while the appliance is booting.

In the BIOS, navigate to the IPMI page.
On the IPMI page, select BMC Network Configuration, and press Enter.
Figure 293: IPMI page > BMC Network Configuration option
On the BMC Network Configuration page, select Update IPMI LAN Configuration, press Enter, and select Yes.
Figure 294: BMC Network Configuration page > Update IPMI LAN Configuration
Stay on the BMC Network Configuration page, select Configuration Address Source, press Enter, and select Static.
Figure 295: BMC Network Configuration page > Configuration Address Source
Still on the BMC Network Configuration page, configure the Station IP Address, Subnet Mask, and Gateway IP Address individually.
Figure 296: BMC Network Configuration page > Station IP Address, Subnet Mask, Gateway IP Address
Press F4 to save the settings, and exit from the BIOS.
About a minute later, you will be able to log in on the IPMI web interface.
When using a TSA certificate generated with Windows Certificate Authority, you might see a similar error message:
Incomplete TSA response received, TSA HTTP server may be responding slowly; errno='Success (0)', timeout_seconds='30'
When generating the certificate, make sure that you do the following:
Optional Key Usage: If Key Usage is present, it must be digitalSignature and/or nonRepudiation. Other values are not permitted. Make sure that in Encryption, Allow key exchange without key encryption (key agreement) is selected.
In Encryption, do NOT select Allow key exchange only with key encryption (key encipherment), because it will result in errors.
