Intern strömkabel Alphacool 25054 80 m rak kontakt

The Alphacool front I/O panel for 1U to 4U server cases provides basic front connectivity and status indicators for server racks. It integrates two USB 2.0 ports plus power and reset switches, and a set of status LEDs for power, hard disk activity and network connections. The PCB is secured with four screws using mounting holes with a 3.5 mm inner diameter and center-to-center distances of 74 mm x 24 mm.

Advantages

This front I/O panel combines USB 2.0 connectivity with clear status indication for HDD, power and up to three network links. All LEDs and switches use 2-pin connectors to simplify installation and replacement. The compact mounting pattern and four-screw fixation make it suitable for standard Alphacool server rack front panels.

Suitable for

• 1U–4U Alphacool server cases
• Server racks requiring front USB 2.0 ports and basic status LEDs
• Systems where easy replacement of front-panel cabling is needed

Key specifications

• Connectors: two USB 2.0 ports (9-pin header cable), multiple 2-pin connectors for LEDs and switches
• LEDs: HDD activity, power indicator, three network status LEDs
• Switches: power and reset (2-pin connectors)
• Mounting: 4 screws, mounting hole inner diameter 3.5 mm; center-to-center distances 74 mm x 24 mm
• Cable set: 8 cables total; 7 two-pin LED/switch cables and 1 USB 2.0 9-pin header cable; cable length 80 cm (pure length without connectors)

How to use

Mount the front I/O panel in the server case using the four supplied screws aligned to the 74 mm x 24 mm hole pattern. Connect each 2-pin LED or switch cable to the corresponding header on the motherboard or rear I/O board, and attach the USB 2.0 9-pin header cable to the motherboard's internal USB header. Ensure correct polarity for 2-pin connectors where applicable. After connections are secure, test power, reset, USB ports and LED indicators to verify proper operation.

Recommendations

Use the included 80 cm cable set to route connections cleanly inside the chassis, keeping LED and USB cables away from fans and hot components. Verify connector orientation before applying power to avoid reverse polarity on 2-pin headers.
