Chapter 3: Preparing for Management
3. Preparing for Management
You can remotely manage this media converter via Telnet®or a Web browser (such as Microsoft®Internet Explorer®or Mozilla®
Firefox®) to access and configure the media converter from anywhere on the network.
3.1 Preparation for Web Interface
The Web management page allows you to use a standard web browser (such as Microsoft Internet Explorer, Google®Chrome®or
Mozilla Firefox) to access and configure the media converter from anywhere on the network. Before you attempt to use the Web
user interface to manage media converter operation, verify that your media converter is properly installed on your network and
that every PC on this network can access the media converter via the Web browser.
1. Verify that your network interface card (NIC) is operational, and that your operating system supports TCP/IP protocol.
2. Power up the media converter power and connect your computer to the media converter.
3. The media converter default IP address is 192.168.2.1. The media converter and the connected PC should be located within the
same IP Subnet.
4. Change your computer's IP address to 192.168.2.XX or other IP address that is located in the 192.168.2.x subnet (For example:
IP Address: 192.168.2.30; Subnet Mask: 255.255.255.0).
Figure 3-1. TCP/IP screen.
5. Launch the Web browser on the PC.
6. Type http://192.168.2.1 (or the IP address of the media converter). And then press Enter.
7. The login screen will appear next. See Figure 3-2.

Figure 3-2. Login screen.
8. Type in the username and password. The default username and password are both admin. The Welcome page appears.
Figure 3-3. Welcome page.
If you can't login to the media converter, the following steps can help you to identify the problem.
1. In DOS command mode, type "ipconfig" to check the NIC's setting. Type the "ping 192.168.2.1" to verify a normal response
time.
2. Check the security and firewall settings of your computer.
3. Try a different Web browser.
4. Clear your Web browser’s browsing history.
For more information, refer to the Appendix: IP Configuration for Your PC.
3.2 Preparation for Telnet Interface
If your Windows®OS is Win XP, Win 2000 or early version, you can access the Telnet console by the default command. If your OS
is Windows 7 or a later version, please download the terminal tool, such as HyperTerminal or Putty.
To connect via Telnet:
1. Go to Start -> Run -> cmd. Then press Enter.
2. Type the telnet 192.168.2.1 address (or the IP address of the media converter). Then press Enter.

724-746-5500 | blackbox.com
Page 12
Chapter 3: Preparing for Management
Access Telnet with Putty:

Table 4-1. Converter Configuration screen options.
Option Description
Jumbo Frame (9K) Enable this function for Jumbo Frame packet (9K) transmitting.
Link Transparent To enable Remote Fault Detect and Link Loss Carry Forward functions, select
this option.
Remote Fault Detect When enabled, the fiber port will be able to receive OAM packets. The media
converter will set local RJ-45 port link up/down according to the remote media
converter’s RJ-45 port’s link status.
NOTE: The Link Transparent function must be enabled for Remote Fault Detect
to take effect.
Link Loss Carry Forward When enabled, the fiber port link will be down when the RJ-45 port link is
down, and the fiber port will resume connection when the RJ-45 port’s
connection is back on.
NOTE: The Link Transparent function must be enabled for Link Loss Carry
Forward to take effect.
Forward CRC Error Frame Packets with CRC error will still be transmitted if this function is enabled. If this
function is disabled, packets with CRC error will be dropped instead.
Forward Pause Frame The media converter will forward pause frames and regard them as normal
packets if this function is enabled.
Management Packet High Priority QoS will be enabled if this function is enabled. Four queues will be enabled,
and queue 3’s priority will be set to “strict.” All management packets, such as
802.3ah OAM, SNMP packets will be in queue 3 to guarantee bandwidth.
Broadcast Storm Filter, Multicast Storm Filter,
Unknown DA Unicast Storm Filter
When too many broadcast/multicast/unknown DA unicast packets arrive in a
period time, the media converter will drop these packets if this function is
enabled.
4.2.4 Port Configuration

Egress Link Type Description
Replace Tag The media converter will remove VLAN tags from packets and add new tags. The tag
inserted will be the ingress port’s “Default Tag,” which is indexed by port “Port
based VLAN index.” This is replacement processing for tagged packets and insertion
for untagged packets.
Remove Tag The media converter will remove VLAN tags from packets if these packets are tagged
during transmission. The media converter will not modify packets received without
tags.
Add Tag The media converter will add VLAN tags to packets if these packets are not tagged
during transmission. The media converter will not add tags to packets already tagged.
The inserted tag is the ingress port’s “Default tag,” which is indexed by the port’s
“Port based VLAN index..”
