Initial Setup

ZTE OLT initial steps

Step 1: Connect to the OLT

Connect to the OLT using one of these methods:

Telnet: Use Putty with the default IP address 136.1.1.100
Serial Cable

: Connect to CL1 or CLI port using the original SERIAL cable with the correct pinout
- Common serial settings: 9600-8-N-1, 57600-8-N-1, or 115200-8-N-1
Mikrotik Console: If your Mikrotik has an RJ45 CONSOLE port, you can use a LAN cable from this port to the OLT CLI port

Important Information:

Factory IP address for ZTE C3xx OLTs: 136.1.1.100
Default username: zte
Default password: zte
If the console displays > instead of #, enter the enable command to gain high privilege mode
Default password for "enable" mode: zxr10

For Telnet Connection:

Connect an ethernet cable to the dedicated (out-of-band) management port of the OLT
- This management port is typically labeled 10/100 or MNG
- Located near the CL1 or DIAG port
- This is an isolated port for management only and cannot transport customer traffic
Configure your PC or Mikrotik ethernet port with IP address 136.1.1.1/255.255.255.0
Verify connectivity by pinging 136.1.1.100
Connect using:

telnet 136.1.1.100
Trying 136.1.1.100...
Connected to 136.1.1.100.

Step 2: Enable Plug-and-Play Detection

Enable PnP detection of OLT boards and add the chassis type:

For C320 OLT:

conf t
set-pnp enable
add-rack rackno 1 racktype C320Rack
add-shelf rackno 1 shelfno 1 shelftype C320_SHELF

For C300 OLT:

conf t
set-pnp enable
add-rack rackno 1 racktype IEC19
add-shelf rackno 1 shelfno 1 shelftype IEC_SHELF

Verify the status of the cards using:

show card

Example output:

Step 3: Configure Management IP Address

Configure a new management IP address on the (out-of-band) mng1 interface:

conf t
interface mng1b
ip address [IP] [MASK]

Reconnect to the OLT using the new IP address you assigned.

Add the default gateway and save configuration:

conf t
no ip route 0.0.0.0 0.0.0.0
ip route 0.0.0.0 0.0.0.0 [IP of the GATEWAY]
exit
write

Step 4: Create Dedicated Username/Password

Create a username/password that will be used between QuickOLT and your OLT:

conf t
username QuickOLTusr password (enter a strong password) max-sessions 16 privilege 15

Step 5: Enable Telnet Service

Enable telnet service (typically disabled by default):

conf t
no ssh server only

Connecting to QuickOLT

At this stage, your OLT is ready to be interconnected with the QuickOLT system:

Open your quickolt.com site
Go to Settings → OLTs → Add OLT
Fill in the required fields
Click the Save button

Additional Settings

If you use QuickOLT, these are configured automatically (no manual configuration needed):

conf t
auto-write enable
auto-write 18:00:00 everyday
mib-compatibility iftable v2
ntp server 20.101.57.9 priority 1 version 4
ntp server 216.239.35.4 priority 2 version 4
ntp enable

Optional: In-band IP Configuration

You can configure an "in-band" IP address on a VLAN interface:

conf t
vlan 300
exit
interface vlan300
ip address [IP] [MASK]

Note: This is useful when you want to manage the OLT using the same physical interface that is used for normal traffic. However, this is not recommended because if a loop occurs in the ONT that is undetected by the ONT/OLT, and the uplink port is shutdown by the uplink device as a reaction to the loop, you will also lose IP connectivity with the OLT.
