12-Port 1000BASE-TX L2 Managed PoE Switch with 2 SFP Dual Media Ports
If you forget the password, click the link of Forget Password in Web UI or press the Ctrl button, then type Z in
the CLI login screen. The system then displays a serial number. Write down this serial number and contact
Black Box—we'll give you a temporary password. Type in this new password as ID and Password, and the system
will allow you to temporarily log into the system with manager authority. This password allows you to login to
the system only one time, so modify your password immediately after you log into the system successfully.
To modify your password, type in the complete new username and password. The switch will not give you a
shortcut to the username automatically. This looks inconvenient, but it provides additional system security.
The switch supports a simple user management function, allowing only one administrator to configure the
system at a time. If two or more users use the administrator's identity, the switch will allow only the one who
logs in first to configure the system. Other users, even with an administrator's identity, can only monitor the
system. Users who have no administrator's identity can only monitor the system. A maximum of three users can
log in simultaneously.
To optimize the display effect, we recommend using Microsoft® Internet Explorer® version 6.0 or above,
Netscape® V7.1 or above, or FireFox V1.00 or above with a resolution of 1024 x 768. The switch supports a
neutral Web browser interface.
4.1 Home Overview
Once you log into the switch, the Home screen appears.
At the top of the screen, the switch's front-panel diagram appears. The linked ports display green, and the
unlinked ports appear dark. The slot shows only a cover plate if no module exists, and it shows a module if a
module is present. The module image depends on the one that's installed in the switch. If disconnected, the
port will appear dark; if linked, it will be green.
Simply click on the ports in the switch diagram to browse the information for a specific port. An information
window appears, containing Link, State, Auto Negotiation, Speed/Duplex, Flow Control, Ingress All State,
Ingress All Rate, Ingress Storm State, Egress All State, Egress All Rate, Tx Byte, Rx Byte, Tx Packet, Rx Packet,
Tx Collision, RX Error Packet, and the Close button.
In the left top corner of the screen, a pull-down list appears for Auto Logout. This is a security function meant
to prevent illegal users from accessing the switch. If you select ON, the system will log out automatically when
there is no action on the device for three minutes. If you select OFF, the screen will remain visible to the user.
The default setting is ON.
On the left side of the screen, the main menu tree for the Web is listed. Options (in a vertical list on the left
side of the screen) include System, Port, Mirror, Bandwidth, QoS, SNMP, IGNP Snooping, Max. Packet Length,
DHCP Boot, VLAN, MAC Table, GVRP, STP, Trunk, 802.1x, Alarm, Configuration, Diagnostics, TFTP Server,
Log, Firmware Upgrade, Reboot, and Logout. These options are described in Sections 4.2 through 4.24.
