Hikvision DS-3E1510P-SI 8 Port Managed PoE Switch, 2 x Gigabit SFP Port, Extended Mode, 110W

Difference Between Hikvision DS-3E1510P-EI and DS-3E1510P-SI

The Hikvision DS-3E1510P-EI and DS-3E1510P-SI are both 8-port Gigabit smart managed PoE switches, commonly used in IP surveillance and networking. While they are similar in design and core function, they have key differences:

---

1. Uplink Port Type:

• DS-3E1510P-EI: 2 × Gigabit RJ45 uplink ports

• DS-3E1510P-SI: 2 × Gigabit SFP fiber optic uplink ports
  This makes the SI version more suitable for longer distance backbone connections via fiber.

---

2. MAC Address Table:

• DS-3E1510P-EI: 4K MAC address entries

• DS-3E1510P-SI: 8K MAC address entries
  Larger MAC table in the SI model supports more connected devices in complex networks.

---

3. Internal Packet Buffer (Cache):

• DS-3E1510P-EI: 1.5 Mbits

• DS-3E1510P-SI: 4.1 Mbits
  Greater buffer in the SI model can help reduce packet loss during high traffic.

---

4. Operating Temperature Range:

• DS-3E1510P-EI: 0°C to 40°C

• DS-3E1510P-SI: -10°C to 55°C
  The SI version is more rugged, suitable for harsher environments.

---

Summary: Choose the DS-3E1510P-EI for general use in standard indoor environments with RJ45 uplinks. Opt for the DS-3E1510P-SI if you need fiber uplinks, higher performance in terms of device count, or environmental durability.
