Chapter 1 Product Overview
1.1 Introduction
H3C S1526 Smart Ethernet Switch (hereinafter referred to
as the S1526) is suitable for the networking of small and
medium-sized enterprises, Internet cafe and households. It
provides one console port, 24 × 10/100Base-TX autosensing
Ethernet ports and two 1000 Mbps uplink combo ports.
Note:
Port 25 and port 26 are 1000 Mbps uplink combo ports. Each
combo port supports one 10/100/1000Base-T autosensing
Ethernet port and one 1000 Mbps SFP module port, which,
however, cannot work simultaneously. If both are enabled
simultaneously, the SFP module port, which has a higher
priority, will be active, while the 10/100/1000Base-T port will be
inactive.
1.2 Features
The S1526 offers rich features as listed below.

2.2.5 User Session Timeout
If your session is inactive for a certain period of time after
you log in to the Web-based NMS, you will be automatically
logged out and the system will display the [Web-based NMS
Login] dialog box shown in Figure 2-1. The changes you have
made to the configuration during your session, however, will
remain on the Web page. To resume your operation, you need
