Installation Requirements:
- Mount in a standard 19″ equipment rack (1U height)
- Provide AC power to the internal 351 W power supply
- Connect at least one Gigabit Ethernet port to the management network
- Use the DB-9 RS-232 port for initial console configuration
- Ensure adequate rack ventilation; operating temperature 50°F–95°F (10°C–35°C)
- Initial setup requires connection to a monitor (VGA) and keyboard/mouse (PS/2) or console cable
Usage Precautions: This is a first-generation ACS 1121 appliance running ACS 5.1 — verify software license and support status with Cisco for current deployments. Operating temperature range is limited to 10°C–35°C; do not deploy in environments outside this range. The unit draws 351 W; ensure the rack PDU provides adequate power. Not ENERGY STAR certified. For initial configuration, use the serial console (DB-9) before network management is enabled.
