Intel® Server System "Emerald Ridge” Integrated Baseboard Management Controller EPSAdvanced ManagementFeature Support6.4.2 Embedded Web ServerThe BMC provides an embedded web server for out-of-band management. User authenticationis handled by IPMI user names and passwords. Base functionality for the embedded web serverincludes:Power Control: Control limited by IPMI user privilege for IPMI Chassis NetFunctioncommands.Sensor Reading: Access limited by IPMI user privilege for IPMI Sensor NetFunctioncommands.SEL Reading: Access limited by IPMI user privilege for IPMI Storage NetFunctioncommands.KVM/Media Redirection: Access limited by IPMI user privilege. Only available when theIntel ® RMM3 is present.IPMI User Management: Access limited by IPMI user privilege for IPMI ApplicationNetFunction commands.The web server is available on all enabled LAN channels. If a LAN channel is enabled, properlyconfigured, and accessible, the web server will be available.The web server may be contacted via HTTP or HTTPS. SSL certificates may be modified usingthe web server. The web server’s port (80/81) may not be changed.For security reasons, the null user (user 1) may not be used to access the web server. Theminimum length for setting user name and password through EWS is 4 and 8 respectively. Thesession inactivity timeout for the embedded web server is 30 minutes. This is not userconfigurable.6.4.2.1 Network Port UsageThe KVM and media redirection features use the following ports:• 5120 – CD Redirection• 5123 – FD Redirection• 5124 – CD Redirection (Secure)• 5127 – FD Redirection (Secure)• 7578 – Video Redirection• 7582 – Video Redirection (Secure)6.4.3 Local Directory Authentication Protocol (LDAP)The BMC firmware supports the Local Directory Authentication Protocol (LDAP) protocol foruser authentication. IPMI users/passwords and sessions are not supported over LDAP.LDAP usage may be configured through the embedded web server for authentication of futureembedded web sessions.Revision 1.1Intel ® Confidential 79
BMC-HSC InteractionsIntel® Server System "Emerald Ridge” Integrated Baseboard Management Controller EPS7. BMC-HSC Interactions7.1 HSC AvailabilityEmerald Ridge supports Hot-Swap Controller (HSC); the HSC is not available when the systemis in standby. The HSC requires at least three seconds after DC-power-on to reach a workingstate where it will respond to IPMI commands. The state of the HSC is not preserved acrosssystem reset or AC/DC cycle.When a single HSC is present in a system, it will respond on the primary IPMB at address C0h.When two HSCs are present, the “primary” HSC will respond at address C0h, and the“secondary” HSC will respond at address C2h.7.2 InteractionsAll HSC interaction is dependent on a properly formatted type 12 (management controller) SDRentry per HSC. Without a type 12 entry for the HSC, the BMC will not attempt any HSCcommunication with the exception of IPMI bridging commands.For each type 12 SDR found, the BMC will:Attempt to verify the presence of the HSC using an IPMI “Get Device ID” command. Thisoccurs when the system is DC powered-on or reset.If the HSC is not found, or is in firmware update mode, the BMC will suspendcommunication with the HSC. Communication will resume if the HSC exits firmware transfermode, or the system is reset (at which time, the HSC will be queried again).Send sensor initialization commands during the BMC’s IPMI initialization agent runtime. Theinitialization command sequence is described in the Intelligent Platform ManagementInterface Specification Second Generation v2.0.Sensor initialization data for the HSC is kept within the BMC’s SDR, and is distributed aspart of the BMC’s SDR package.Push the current power state to the HSC using the HSC supported OEM command, SetPower Supply State. This happens in 30 second intervals, unless there is an emergencypower state change.For Details on the Set Power Supply State command, please see the appropriate platformHot Swap Controller (HSC) EPS.Scan HSC disk status sensors at a 30 second interval, and cause the system status LED toindicate a fault condition if any of the disks are experiencing a fault.Disk fault detection is done by the host bus adapter, and is not controlled by the HSC orBMC. The HSC receives disk fault status through a separate management bus. The BMCmay only read disk fault status from the HSC.The BMC firmware will always bridge commands through the BMC to the HSC via the IPMB.This is supported by the IPMI command, Send Message. This command is used by systemsoftware to access the HSC status or to update the HSC firmware.80Intel ConfidentialRevision 1.1
