Hardware Specifications

Serial

The stick has a TTL 3.3V UART console (configured as 115200 8-N-1) that can be accessed from the SFP connector, but no components are mounted.

The UART can be accessed by any of the following methods.

• Touch the needle to a specific point
• Shorting a specific pad to access from SFP

Access from PCB

The UART can be accessed by connecting a wire or touching a needle to the following points.

Access from SFP

By shorting these two points with solder, you can access the UART from SFP pins 2 and 7.

Usage

Configure IP Address

Set your PC’s IP address to 192.168.0.5/24

Download Custom Firmware

Download the following firmware files and place them on a TFTP server (e.g., 3CDaemon):

• SIEPONA_rootfs.bin
• SIEPONA_kernel.bin

Log in to the Stick root shell

$ ssh root@192.168.0.1

root@XE-99S:~#

Upload Firmware to the Stick

Run the following commands to download the firmware via TFTP:

cd /tmp
tftp -r SIEPONA_kernel.bin -g 192.168.0.5
tftp -r SIEPONA_rootfs.bin -g 192.168.0.5

Reset Configuration

mkdir /userdata/upper
rm -r /overlay/upper/*

Flash the Firmware

Execute the following commands to write the firmware:

flash_erase /dev/$(awk -F: '$2 ~ /"kernel1"/ {print $1}' /proc/mtd) 0 0
nandwrite -p /dev/$(awk -F: '$2 ~ /"kernel1"/ {print $1}' /proc/mtd) /tmp/SIEPONA_kernel.bin
flash_erase /dev/$(awk -F: '$2 ~ /"rootfs1"/ {print $1}' /proc/mtd) 0 0
nandwrite -p /dev/$(awk -F: '$2 ~ /"rootfs1"/ {print $1}' /proc/mtd) /tmp/SIEPONA_rootfs.bin

flash_erase /dev/$(awk -F: '$2 ~ /"kernel0"/ {print $1}' /proc/mtd) 0 0
nandwrite -p /dev/$(awk -F: '$2 ~ /"kernel0"/ {print $1}' /proc/mtd) /tmp/SIEPONA_kernel.bin
flash_erase /dev/$(awk -F: '$2 ~ /"rootfs0"/ {print $1}' /proc/mtd) 0 0
nandwrite -p /dev/$(awk -F: '$2 ~ /"rootfs0"/ {print $1}' /proc/mtd) /tmp/SIEPONA_rootfs.bin

Reboot the Stick

Reboot or power off the device:

reboot

The reboot process takes approximately 180 seconds. If an error occurs with the reboot command, simply turn off the power.

Access the Web UI

Open the following URL in your browser:

• http://192.168.0.1

Set PON MAC Address

From the menu, select “PON MAC Address” and configure the EPON MAC address of your ONT.

Configure Forced Bridge Mode

From the menu, select “Forced Bridge mode” and enable it.

Reboot the Stick

Select “Reboot” from the menu. The reboot process takes approximately 180 seconds.

Connect the Fiber

Connect the ISP fiber cable to the stick.

ONT Authentication

Once authentication is successful, the “PON” and “AUTH” status indicators under the “Status” menu will show “OK”. At this point, the stick is successfully connected to the ISP network.

EPON ONT status

Getting the operational status of the ONT

Check the ONT Registration State with the following command:

ca-iros-> wca_epon_mpcp_registration_status_get -device_id 0 -port_id 0x20007 -llid 0
[deregistration_cause = 0]
[mpcp_llid = 65535]
[olt_mac_addr = 00:00:00:00:00:00]
[reg_state = 0]
[retry_times = 0]
Return Value : 0 - CA_E_OK
0

Check the ONT auth state with the following command:

ca-iros-> wca_epon_llid_traffic_enable_get -device_id 0 -port_id 0x20007 -llid 0x0
[downstream = 1]
[upstream = 1]
0

EPON/OAM TLV settings

The XE-99S Custom firmware uses a web UI for configuration.
