Product Description

Product Parameters

  

Flexible Networking Capability

• The S1700 managed switch provides 10/100/1000BASE-T, 1000BASE-X, and 10GE SFP+ ports. It supports multiple interface types such as access, trunk, and hybrid.

• The S1700 managed switch provides swappable Small Form-Factor Pluggable (SFP) optical modules for GE optical fiber connections and swappable Small Form-Factor Pluggable plus (SFP+) optical modules for 10GE optical fiber connections. The length of optical fibers can be selected according to the transmission distance.

• The S1700 managed switch supports the Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP) (supported only by fully-managed switches) to prevent loops and provide rapid switchover.

Comprehensive Security Measures

• The S1700 managed switch supports port-based MAC address filtering to prevent hackers from attacking user terminals or networks by forging MAC addresses.

• The S1700 managed switch supports Remote Authentication Dial In User Service (RADIUS) authentication, 802.1x authentication, and MAC address authentication to prevent unauthorized users from accessing the enterprise network.

• The S1700 fully-managed switch supports the DHCP snooping function, which generates user binding entries based on MAC addresses, IP addresses, IP address leases, VLAN IDs, and interface numbers of users. This function protects networks against common attacks such as bogus IP packet, man-in-the-middle, and bogus DHCP server attacks.

Comprehensive QoS Policies

• The S1700 managed switch can classify traffic based on 802.1p fields, VLAN IDs (only fully-managed switches), MAC addresses (only fully-managed switches), and ACL (only fully-managed switches).

• Each port of an S1700 managed switch supports up to 8 queues (each port of S1728GWR-4P supports up to 4 queues). In addition, the S1700 managed switch supports weighted round robin (WRR), Priority Queuing (PQ), WRR + PQ (only S1720 and S1730S), Weighted Deficit Round Robin (WDRR) (only S1720 and S1730S), and PQ + WDRR (only S1720 and S1730S) queue scheduling algorithms to effectively ensure high-quality voice, video, and data services.

Energy-Saving Design

• Some models of the S1700 use natural heat dissipation, which avoids power consumption and noise of fans.

  The following switch models have fans and use forced air cooling: S1700-52GFR-4P-AC, S1720-28GWR-PWR-4P, S1720-28GWR-PWR-4P-E, S1720-28GWR-PWR-4X, S1720-28GWR-PWR-4X-E, S1720-52GWR-4P, S1720-52GWR-4P-E, S1720-52GWR-4X, S1720-52GWR-4X-E, S1720-52GWR-PWR-4P, S1720-52GWR-PWR-4P-E, S1720-52GWR-PWR-4X, S1720-52GWR-PWR-4X-E, S1720X-16XWR, S1720X-32XWR, S1720X-16XWR-E, S1720X-32XWR-E, S1720-28GFR-PWR-4P, S1720-52GFR-4P, S1720-52GFR-PWR-4P, S1730S-S24P4S-A, S1730S-S24P4S-MA, S1730S-S48T4S-A, S1730S-S24T4X-A, S1730S-S48P4S-A, and S1730S-H48T4S-A.

• The chip changes to the power saving mode when a service port is idle (no connected device is detected).

• The switch uses energy-saving chips. With the help of the intelligent device management system, the chips not only improve system performance but also greatly reduce power consumption of the entire system.

Cutting-Edge Surge Protection Capability

The S1700 managed switch adopts the Huawei patented surge protection technology to protect the equipment. This strong surge protection capability greatly reduces the probability of damage caused by lightning, even when the equipment cannot be grounded.
