How Do I Change the Password for Web Login?




If you forget or want to change the web login password, log in to the switch through the console port, Telnet, or STelnet and set a new password after login.

NOTE:
The Telnet protocol has security vulnerabilities. It is recommended that you log in to the device through the console port or using STelnet V2.
# Set the user name and password to admin123 and Huawei@123 respectively.

The Optix OSN 1500A Hardware Description (2) – Slot Allocation



An OptiX OSN 1500A subrack has only one layer structure. The subrack consists of a board area, an auxiliary interface board area, a power interface board area, a fan area, and a cable routing area.
Figure 1 Structure of an OptiX OSN 1500A subrack 




1. Fan area
2. Processing board area
3. Power interface board area
4. Auxiliary interface board area
5. Cable routing area
-

The functions of the areas are as follows:
·                 Fan area: This area houses one fan module, which dissipates heat generated by the equipment.
·                 Processing board area: This area houses the service boards of the OptiX OSN 1500A.
·                 Power interface board area: This area houses two power interface boards, which supply power to the equipment.
·                 Auxiliary interface board area: This area houses the line, tributary, and Ethernet processing boards of the OptiX OSN 1500A.
·                 Cable routing area: This area houses fiber jumpers and cables in a subrack.
NOTE:
An interface board is also called an access board or a transit board. An interface board provides physical interfaces for optical signals and electrical signals, and transmits the optical signals or electrical signals to the corresponding processing board.


The slot allocation
An OptiX OSN 1500A subrack has only one layer, where 12 slots are available before division of slots. After slot division, there are 14 slots. The mappings between the slots for the access boards and the slots for the processing boards and the mappings between paired slots are specified.
Figure 2 shows the slot layout (before slot division) of an OptiX OSN 1500A subrack.
Figure 2 Slot layout of an OptiX OSN 1500A subrack (before slot division) 

Each of slots 12 and 13 in an OptiX OSN 1500A subrack can be divided into two half-width slots. See Figure 3.
Figure 3 Slot layout of an OptiX OSN 1500A subrack (after slot division) 
The slots in an OptiX OSN 1500A subrack are allocated as follows:
·                 Slots for line unit, SCC unit, cross-connect unit, and timing unit integrated boards: slots 4-5
·                 Slots for processing boards before division of slots: slots 6-9 and 12-13
·                 Slots for processing boards after division of slots: slots 2-3, 6-9, and 12-13
·                 Slot for an orderwire board: slot 9 (also for a processing board)
·                 Slot for an auxiliary interface board: slot 10
·                 Slots for power interface boards: slots 1 and 11
·                 Slot for a fan board: slot 20
 NOTICE:
Do not divide slots by yourself. If slots need to be divided, the division is performed before delivery.

Mapping Between Slots for Interface Boards and Slots for Processing Boards

Table 1 lists the mapping between slots for interface boards and slots for processing boards.
Slot for Processing Board
Slot for Interface Board
Slot 12
Slots 6 and 7

Paired Slots

If overhead bytes pass through the backplane bus between two slots, the two slots are called paired slots. Paired slots achieves automatic transparent transmission of overhead bytes such as K bytes, D bytes, and E1 overhead bytes. This improves multiplex section protection (MSP) switching performance and protects orderwire and DCC communication with other NEs even after the system control board on the local NE cannot be
detected. Table 2 lists paired slots.

The Optix OSN 1500 Hardware Description (1) – Structure Overview



The optix OSN 1500 hardware overview
The OptiX OSN 1500 consists of a cabinet, subracks, and boards.
The OptiX OSN 1500 can be installed in an ETSI cabinet (300 mm or 600 mm deep) or a 19-inch standard cabinet. It can also be installed against the wall.
The OptiX OSN 1500 uses various boards and forms a system architecture where the SDH cross-connect matrix unit and the packet switching unit are the core. As shown in Figure 1, the system architecture of the OptiX OSN 1500 consists of the units listed in Table 1.

The Cabinet of Huawei SDH OSN 1500
The OptiX OSN 1500 can be installed in an ETSI cabinet (300 mm or 600 mm deep) or a 19-inch standard cabinet or many other cabinets.
There are 300 mm and 600 mm ETSI cabinets, of which 300 mm ETSI cabinets are available in two types: T63 cabinets and N63E cabinets. Figure 2 shows the appearance of a T63 cabinet and the appearance of an N63E cabinet.
