3. Installation of 2.5-inch IDE hard drive on motherboard (distinguishing between 6840/6840V fixed structures);

4. RTM side hard disk and CF card assembly;

5. PMC sub card installation (lower level extensions cannot be used when the hard disk occupies PMC1);

6. RTM transition module docking (must match the corresponding motherboard model, mixing may damage hardware);

7. CompactPCI chassis full machine insertion, hot plug and power on verification (blue hot plug light off indicates in place readiness).

2. OEM extension specific instructions: firmware version read, remote power on/off, SMBus switch, fault debugging variable read, IPMB address rescan;

3. IPMB address mapping, onboard sensor list (3.3V/5V/12V voltage, system temperature, BMC watchdog);

4. Known limitations: BMC does not have an independent RTC, and the power on timestamp is reset to zero; Sensor SDR flash read-only;

5. Supporting reference standards: IPMI v1.5, PICMG2.9 specification documents.

Safety operation standards

1. Installation and maintenance must be anti-static; Do not block the cooling air duct of the chassis;

2. Risk warning for lithium battery replacement (mismatched batteries pose a risk of explosion);

3. Water ingress, cable damage, and hardware deformation must be handed over to professional maintenance personnel, and self opening of covers is prohibited;

4. Use only power within specifications and keep away from moisture, heat sources, and liquids.
