### 6. Installation & Setup

Requirements:
- 19" rackmount space (1U height).
- One VGA monitor, one PS/2 keyboard, and one PS/2 mouse for console side.
- For each connected computer: one HDB15 VGA cable and two PS/2 cables (keyboard and mouse).

Installation Steps:
1. Mounting: Attach the included rack brackets to the KVM drawer and secure it in a 19" rack.
2. Video Connections: Connect each PC’s VGA output to the corresponding KVM port using HDB15 male‑to‑male cables.
3. Mouse Connections: Connect each PC’s PS/2 mouse port to the KVM’s mouse port.
4. Keyboard Connections: Connect each PC’s PS/2 keyboard port to the KVM’s keyboard port.
5. Power Connection: Attach the DC power adapter to the KVM unit and plug into AC power.
6. Boot Sequence: Power on the KVM switch, then sequentially boot each connected computer.
7. Daisy‑Chain Setup (optional): Connect additional SMK595 units using the 3‑in‑1 daisy‑chain cable kit. Up to 8 levels can be chained.
8. Configuration: Use the OSD to assign system names, set scan intervals, and configure password protection.

Notes:
- Ensure all devices are powered off before connecting cables.
- For daisy‑chain configurations beyond five banks, use a VGA‑100 extender to maintain signal quality.
- The KVM switch draws power from both the adapter and connected PCs’ PS/2 ports; however, the adapter must remain connected for stable operation.
