+# Hasivo S1100WP-8GT-1SX-SE
+
+RTL8373-based 8×2.5G PoE + 1×SFP switch.
+
+### Label specifications
+
+- **Manufacturer**: Hasivo
+- **Model**: S1100WP-8GT-1SX-SE
+- **Ports**:
+  - 8 × RJ45: 10/100/1000/2500 Mbps with PoE
+  - 1 × SFP: 1G / 2.5G / 10G
+- **Power input**: DC 52V 2.5A
+- **Stock firmware defaults**: IP 192.168.0.1, user/password `admin`/`admin`
+
+### What works
+
+- All eight 2.5GBASE-T RJ45 ports at 10/100/1000/2500 Mbps (PoE is not configurable via RTLPlayground)
+- SFP port supporting 1G, 2.5G and 10G modules
+- LEDs: green (2.5G) and amber (1G/100M/10M) per copper port; combined link/act on the SFP port

+### Port layout
+
+| Logical port | Physical port | Type   |
+|--------------|---------------|--------|
+| 1-8          | 1-8           | Copper |
+| 9            | 9             | SFP    |
+
+### LED configuration
+
+Copper ports use LED SET0, the SFP port uses LED SET1.
+
+| SET  | LED0                                          | LED2                                                 |
+|------|-----------------------------------------------|------------------------------------------------------|
+| SET0 | Green — lights on 2.5G link with activity     | Amber — lights on 1G / 100M / 10M link with activity |
+| SET1 | All speeds — lights on any link with activity | —                                                    |
+
+### SFP GPIO assignments
+
+| SFP (logical 9) | pin_detect (ModAbs) | pin_los | pin_tx_disable | SerDes | I2C SDA         | I2C SCL             |
+|-----------------|---------------------|---------|----------------|--------|-----------------|---------------------|
+| SFP             | GPIO30_ACL_BIT3_EN  | GPIO37  | GPIO_NA        | SDS1   | GPIO39_I2C_SDA4 | GPIO40_I2C_SCL3_MDC1 |
+
+### Machine configuration
+
+- `reset_pin`: GPIO54_ACL_BIT2_EN
+- High LEDs (pads 27-29): mux = `LED_27 | LED_28_SYS | LED_29`, enable = `LED_28_SYS | LED_29`
+
+### PoE
+
+The 8 copper ports support PoE (power input DC 52V 2.5A). PoE is not configurable via RTLPlayground, and no `struct poe_port` telemetry is configured for this machine.
