device, most likely through the use of the PoE adaptor, as most computers do not
have a PSE port.
Access to management is password protected. The initial user name and
password are both ‘admin’ for a new device. As a security precaution, users are
strongly advised to change both of them before the device is connected to a
network.
Note:
 The default IP address is 192.168.1.2, which needs to be changed to a
valid local address.
 If IP address has being changed before but not remembered, flip the dip-2
on the dip switch to use the default IP temporally.
3.1.3. Optical Port
The socket marked GX on HX.PTP-GM02 is the 100/1000M Ethernet
optical port, supporting auto-negotiation and forced 1000M full duplex mode. A
hot swapable SFP optical module is required to use the optical Ethernet. When
using single-fiber transceiver module, there is only one optical fiber port. The
wavelength of a single-fiber transceiver module refers to its emission wavelength,
which may be 1310nm or 1550nm. Note: single-fiber devices with same
emission wavelengths cannot interwork, matching wavelength modules are
required for interconnection.
When connector is inserted into optical transceiver module socket, the
latching tab should be aligned to the corresponding notch. The bending radius of
pigtail fiber should be no less than 50mm. When optical fiber connector is
inserted or pulled, do not directly pull the optical fiber. Please reserve the
protection plug on SFP optical module. When no optical fiber is connected, please
ensure that the protection plug is inserted to prevent dust from entering.
