Flash
System is abnormal.
Note:
The startup process consists of two stages: System Booting and Gateway Service
Startup. The system booting costs about 1 minute and once it succeeds, both the run
indicator and the alarm indicator light up. Then after the gateway service is successfully
started and the device begins to work normally, the run indicator flashes and the alarm
indicator goes out.
During runtime, if the alarm indicator lights up or flashes, it indicates that the device goes
abnormal. If you cannot figure out and solve the problem by yourself, please contact our
technicians for help. Go to Appendix C Technical/sales Support to find the contact way.

Chapter 2 Quick Guide
This chapter is intended to help you grasp the basic operations of the SR500 gateway in the
shortest time.
Step 1: Confirm that your packing box contains all the following things.
SR500 Series Gateway *1
Angle Bracket *2, Rubber Foot Pad *4, Screw for Angle Bracket *8
220V Power Cord *2
Warranty Card *1
Installation Manual *1
Step 2: Properly fix the SR500 gateway.
If you do not need to place the gateway on the rack, simply fix the 4 rubber foot pads. Otherwise,
you should first fix the angle brackets onto the chassis and then place the chassis on the rack.
Step 3: Connect the power cord.
Make sure the device is well grounded before you connect the power cord. Check if the power
socket has the ground wire. If it doesn‟t, use the grounding stud on the rear panel of the device
(See Figure 1-3) for earthing.
Note: Each SR500 gateway has two power interfaces to meet the requirement for power supply
hot backup. As long as you properly connect and turn on these two power keys, either power
supply can guarantee the normal operation of the gateway even if the other fails.
Step 4: Connect the network cable.
Step 5: Log in the gateway.
Enter the original IP address (LAN 1: 192.168.1.101 or LAN 2: 192.168.0.101) of the SR500
gateway in the browser to go to the WEB interface. The original username and password of the
gateway are both „admin‟. For detailed instructions about login, refer to System Login. We suggest
you change the initial username and password via „System Tools Change Password‟on the
WEB interface as soon as possible after your first login. For detailed instructions about changing
the password, refer to Change Password. After changing the password, you are required to log in
again.
Step 6: Modify IP address of the gateway.
You can modify the IP address of the gateway via „System Tools Network‟on the WEB interface
to put it within your company‟s LAN. Refer to Network for detailed instructions about IP
modification. After changing the IP address, you shall log in the gateway again using your new IP
address.
Special Instructions:
The chassis of the SR500 gateway must be grounded for safety reasons, according to
standard industry requirements. A simple way is earthing with the third pin on the plug or
the grounding studs on the machine. No or improper grounding may cause instability in
operation as well as decrease in lightning resistance.
As the device will gradually heat up while being used, please maintain good ventilation to
prevent sudden failure, ensuring that the ventilation holes (see Figure 1-4) are never
jammed.
During runtime, if the alarm indicator lights up or flashes, it indicates that the device goes
abnormal. If you cannot figure out and solve the problem by yourself, please contact our
technicians for help. Otherwise it may lead to a drop in performance or unexpected
errors.

Appendix B Troubleshooting
1. What to do if I forget the IP address of the SR500 gateway?
Long press the Reset button on the gateway to restore to factory settings. Thus the IP
address will be restored to its default value:
LAN1: 192.168.1.101
LAN2: 192.168.0.101
2. In what cases can I conclude that the SR500 gateway is abnormal and turn to Synway’s
technicians for help?
a) During runtime, the run indicator does not flash or the alarm indicator lights up or flashes,
and such error still exists even after you restart the device or restore it to factory settings.
b) Voice problems occur during call conversation, such as that one party or both parties
cannot hear the voice or the voice quality is unacceptable.
Other problems such as abnormal channel status, inaccessible calls, failed registrations and
incorrect numbers are probably caused by configuration errors. We suggest you refer to
Chapter 3 WEB Configuration for further examination. If you still cannot figure out or solve
your problems, please feel free to contact our technicians.
3. What to do if I cannot enter the WEB interface of the SR500 gateway after login?
This problem may happen on some browsers. To settle it, follow the instructions here to
configure your browser. Enter „Tools > Internet Options >Security Tab‟, and add the current IP
address of the gateway into „Trusted Sites‟. If you change the IP address of the gateway, add
your new IP address into the above settings.
