|
SCSI Bus Termination | LVD/SE: On-board termination, enabled or disabled with a hardware jumper. SCSI termination power source with auto-resetting circuit breaker (TERMPWR)
|
Signaling | 16-bit SE or LVD interfaces |
Flash ROM | Yes, for boot code and firmware |
Serial EEPROM | Yes, it contains Vital Product Data (VPD), HP PCI IDs, SCSI Parameters, and Chip Configuration. It is also configured with the HP part number for easy identification when ioscan is used. |
Safety Characteristics | The HP A7173A adapter board meets or exceeds the UL flamability rating 94 V0. Each bare board is also marked with the supplier’s name or trademark, type, and UL flamability rating. Since these boards are installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit. |
