5.3
Ready LED does not blink
After the unit is powered on, the Ready LED should start to blink. If it does not, try
switching power off and on again. If this error persists, call for support.
5.4
Cannot set up E1 channel
5.4.1
Same LAN domain
When two VQE1s are within the same DOCSIS / Ethernet broadcast domain, try
following.
Check if the transmission network is on.
Check that the network will pass broadcast packets. For a network that suppresses
broadcast packets, as some of the wireless LAN bridges do, disable ARP and manually
setup local and remote MACs.
Check that there is no MAC address conflict on the LAN.
Check that the transmission network has enough bandwidth (more than 2.5Mbps
duplex).
5.4.2
Different LAN domain
When two VQE1s are in different DOCSIS Ethernet broadcast domains, IP headers
must be used, and packets will be routed by a gateway router, try the following.
Check if the default gateway IP is defined correctly.
Check if the local and remote IP is set correctly.
Check for any conflicts in IP or MAC addresses.
Make sure the transmission network has enough bandwidth.
5.5
Downstream reporting slips
Check if the downstream equipment has correct clock mode. At least one of them
must be clock master. Set the VQE1 on master side to loop back timing.
If the downstream equipment on both sides is not synchronized, slips are not
avoidable.
At the transition time after power on or reapplying the E1signal, slips and errors are
acceptable. Such transition may take several minutes.
6.
Web Manager
Web manager supported through anyone of two user data ports.
6.1
Show current status menu
Any local DATA interface of VQE1 supports Web Server management. The
management has three sections: Status, Line Test and Configuration. User name and
password are needed to enter the sections of Line Test and Configuration. Both the
default user name and password are “root” .Customers can modify the user name and
password in the configuration section.
Note that the modifications of Configuration
will be valid after submit and reboot, while the modifications of Line Test (E1
loop-back setting) can be valid only after submit.
After inputting the IP address, status information of VQE1 will be displayed such as
hardware version, software version, IP address, subnet mask, gateway address and MAC
address. The default IP address is 192.168.1.2. Details are shown in fig. 6.1-1.
