Chapter 3 Preparation before Installing and Connection

3.1 Optical port connection

GVM-1101 / GVM-1220 / GVM-1000 supports hot plug SFP port. When one pair of optical modules is

connected, four requirements need to be fulfilled.

1. Optical wavelengths must be the same, especially for single fiber optical ports, require

transmit-receive optical wave with difference frequencies. The transmitting and receiving

operating wavelengths should match each other (for example: if TX is 1310nm, and the

opposite end RX should be 1310nm).

2. The rate of optical modules must be the same.

3. The optical powers must be matching

4. Comply with the Ethernet protocol of IEEE802.3、IEEE802.3u、IEEE802.3z、IEEE802.3x.

3.2 Network-building method

When connecting products in Network, Rules of 3.1 must be obeyed rules for connecting optical ports:

for GVM-1101 / GVM-1220 / GVM-1000 fiber media converters. please build network according to the

following sketch maps.

3.3 Test

Test the optical port connection between the device and Media Converter. After the OAM Discovery of

Media Converter, test RFC-2544 and MIB variable quantity response.

(2)

3.4 Connection between Media converter and other devices with UTP cables

Connecting the media converter and switch/router with cat UTP cables, the cables max length is to

100m. 1. Auto-negotiation of Ethernet port and MDIX/MDI function can be supported.

Chapter 5 WEB Interface

5.1 Login

First, we input the device’s IP address 192.168.1.2 in the web browser, and then we could see the login page.

We must input the correct the password to login the web, otherwise we could not access any web pages. The

default Username is admin and the default password is 123456 and could be changed in the web. If we don’t have

any operations in 15 minutes, we need login again.

When we login the web successfully, we could see the welcome page.

We could click the menu button in the left side of the web page to open the function pages.

5.2 Network Information

This menu is mainly for network interface and port status.

It will show local system information, include MAC, IP, gateway, subnet mask address, software version number

and device description. User could enable/disable remote device control ability. If enable remote device control

ability, we could configure remote device and see remote device’s information. If both this device and remote

device enable TS1000 function, this device is in center mode and Remote device is in terminal mode, this page

will show remote device’s information, include MAC, IP and software version.

Note: We could only enable one device’s remote control ability. If both two devices enable this function, either

device can not control the other one.

5.3 Local Setting

This menu contains local device’s configuration.

5.4 IP Configuration

The OAM Media Converter embeds a DHCP client. We could enable/disable this function through the page.

If we disable DHCP, we should set the IP, gateway, subnet mask by self, and otherwise, these could not be set. They

will be provided by DHCP server. If the DHCP client is enabled, the IP address is provided by DHCP server, so user

should make sure there is a DHCP server in the net before you enable this function.

5.5 Password Setting

In this page, we could change the password. The password must be ‘a’-‘z’, ‘A’-‘Z’, ‘0’-‘9’ and ‘_’.

The max length is 16 characters. In this web, we do not support user purview configuration, and only support one

user name setting. We can't not change user name in the web.

5.6 Converter Configuration

Jumbo Frame (9K): If enable this function, the media converter could pass the max 9KB packet.

Link Transparent: Only if link transparent is enabled, the Remote Fault Detect and Link Loss Carry Forward will take

effect.

Remote Fault Detect: If enable this function, when fiber port enable TS-1000 and receive OAM pkt.

The OAM Media Converter will set local UTP port link up or link down according to remote device’s UTP port link

Status: This function need enable link transparent first.

Link Loss Carry Forward: If enable this function, when the UTP port link down, the fiber port will be forced link down.

And the fiber will be resuming when UTP port link up. This function need enable link transparent first.

Forward CRC Error Frame: If enable this function, the CRC error packet will be pass, otherwise, the CRC error

packets will be dropped.

Forward Pause Frame: If enable this function, The OAM Media Converter will forward pause frame and regard it as

a normal packet.

Management Packet High Priority: If enable this function, The OAM Media Converter will enable QOS.

We enable four queues, and set queue 3 as strict priority. All management packets, such as 802.3ah OAM,

SNMP packets will be in queue 3 to guarantee bandwidth.

Broadcast Storm Filter, Multicast Storm Filter, and Unknown DAunicast Storm Filter: If enable this function, when too

many broadcast/multicast/unknown DA unicast packets arrive in a period time, the packets will be dropped.

5.7 Port Configuration

This page could set local device’s port status, including work mode, flow control ability, ingress and egress rate limit.

There are some predefined rate settings. If user needs some special usage, you could input the rate by self. Because

the rate limit is 64kbps as a minimal step, the input rate should be divided exactly by 64. If the value input is not

divided exactly by 64, for example 65, the program will be change the rate to 64 automatically.

5.8 MIB Counter

The page shows local device’s MIB counters. If click the “clear” button, all MIB counters will be clear to zero. Click the

“refresh” button, show the current MIB counters again.
