Troubleshooting The XLR. Case XLR 550

On power up of the XLR, if the console is connected correctly and the unit is powering up correctly the users should see the XLR going through the boot up process.

After the boot up process has completed the message , “Enter password” will appear. (If the booting process of the equipment has completed before console connection, users may miss the boot messages. In this case, simply input ENTER key into the terminal program and user should be able to see a message saying “Enter password”)

Users should type the password to log into the system. (password is preliminarily set as

“password”; but users may change the password - refer to the CLI manual)

User may configure the system with the instruction set provided in the CLI manual.

NOTE : This H/W installation guide includes 2BASE-TL port connection and verifying its function. Therefore, some basic 2BASE-TL port setting commands are provided here:

Solution

XLR 5xx

XLR 5xxA

-1 Verify that the DC adapter’s cable plug is connected to an operational power source (+100 ~ +240V AC).

-2 Verify that that DC adapter is operational

Verify that the AC power cable plug is connected to an operational power source (+100 ~ +240V AC).

Verify that the console cable’s DB-9 connector and RJ-45 jack is plugged firmly. Verify that communication options are correctly set.

2BASE-TL Port’s LEDs

OFF with no blinking

2BASE-TL Port’s LED blinking but not entering ON state

In normal operation (a pair of devices, one set as CO, the other set asRT), 2BASE-TL

LED will be off if there is no copper pair connected to the port (or if a copper pair is connected at the port but is notterminated at an operational remote device or if the copper circuit isfaulty (i.e. excessive loss or open circuit))

1. Verify that the remote device is operational and the mode is set as different mode from the device itself.

2. Verify that copper pairs are wired correctly in the copper pair. (refer to figure 2-4 )

1. Verify that the line state is normal (state, such as distance). If the distance of the line is too long to sync, it may fail to link up.

LINK / RX LED

TX LED

In normal operation, the network LINK LED is on when a link is detected between the N55x and a remote device.

1. Verify that the CAT5 cable is connected properly to a 10/100Mbps port on an operational Ethernet device.

In normal operation, the network RX LED, TX LED, or both blink when the device detects traffic on the Ethernet port. If the these LED is off and the Network LINK LED is on:

1. Verify that there is Ethernet traffic on the network connection.
