Chapter 2 Product Overview
RC552-FE(A) remote-manageable, bandwidth controllable, and 10/100M auto-sensing Ethernet Media
Converter is Raisecom’s self-developed IEEE802.3ah OAM-capable module, which implements Ethernet
signal electrical-optical conversion.
RC552-FE(A) module can be inserted into Raisecom’s 3U 16-slot chassis, coexisting with other RC series
media converters; and also can be inserted into single slot chassis to act as a standalone device.
When deployed with remote network management, RC552-FE(A) has two working modes: Master and
Slave. The module at central office shall work at Master mode, while the module at customer premise shall
work at Slave mode. The Master module will originate network management and manage the Slave module.
When working at Slave mode, 4 standard OAM functions are supported. They are OAM discovery, MIB
variable request respond, Loopback, and Dying Gasp alarm indication.

Chapter 7 Network Management Features
6.1 Review the Module
When RC552-FE(A) module is inserted into 16-slot chassis with management agent card, customers can review the module
status and also configure the module. The following parameters can be reviewed or configured.

Note: all configurable items of SLAVE module can only be set through MASTER module; only SLAVE module status can
be reviewed locally.
6.2 Configure the Module
In the above table, all configurable items can be set through ‘config module’ command in NMS. These items include copper

Page 16 of 25
interface speed, fault propagation, and etc. However, SLAVE module cannot be configured locally, buy only remotely through
MASTER module. That is to say, if SLAVE module is inserted into 16-slot chassis with management card, customers will only
be able to review its status rather than to configure it.
6.3 Loopback Test
For central office module, customers can enable or disable loopback test through ‘module loopback test’ command, and view
the result through ‘show module’command.

Both network management system and module command line interface can enable or disable loopback test. When enabling
loopback test and assembling loop circuit, customers can connect test equipment to module interfaces and monitor the circuit.
After test, disable loopback test and disassembly the loop circuit. Subscribers’traffics will be interrupted during loopback test.
When using NMS to enable loopback test, the loop will be assembled by the module once receiving the command. And the
module will echo ‘successful’flag if loop circuit is assembled; otherwise echo ‘failed’ flag. After successfully setup loop circuit,
the module will report ‘loopback in progress’ flag to NMS. When using NMS to disable loopback test, the module will
disassemble loop circuit once receiving the command and report ‘loopback finish’flag to NMS.
If the central office module is applied power but not loopback test, the test result shall display ‘failed’.
6.4 Reset the Module
Central office module and remote module can be reset through ‘local module reset’ and ‘remote module reset’ respectively.
Original configuration will be kept as that before reset.

Chapter 8 Configure and Manage RC552-FE(A) through CLI
7.1 Menu Introduction
[1] General overview
RC552-FE(A) module provides user-friendly menu-driven command line interface. Through this interface, customers can
flexibly manage the module, including the following activities:
¾Display the working status of the module
¾Display the fault propagation status
¾Loopback function setup
¾Firmware online upgrade
Note: customers cannot use both NMS and CLI to manage the module simultaneously. Since CLI mode has higher priority,
NMS will not take effect when entering CLI. NMS will only take effect after the module quit CLI mode.
[2] Management methods
¾The console port of RC552-FE(A) is used for local configuration and management
Local console management
Customers can manage the module through connecting a VT100 terminal or a PC or a workstation with terminal simulating
program to the console port of RC552-FE(A). This method is especially suitable for the following situation:
¾The network is not stable or no network management
¾The network management program does not have direct network connection
¾Fault diagnostics
Log on to RC552-FE(A) module
RC552-FE(A) console port default setup is [baud rate: 9600; data bit: 8; parity: 0; stop bit: 1; flow control: none], and VT100
terminal. Before logging on to the module, these parameters shall be applied to the terminal or workstation.
When logging on to RC552-FE(A) for the first time, it will prompt for password, which is default 1234.
7.2 Configure RC552-FE(A) through Console
After connecting standard console cable to the COM port of PC, and start corresponding COM port terminal simulating
program, customers will be able to manage RC552-FE(A) module through menu-driven interface.
7.2.1 Login

Page 18 of 25
Press ‘enter’ button, and input the default password ‘1234’ in command line prompt to enter module management interface.
Note: lower-case input command will be effective; press ‘ESC’to back to upper level menu from current sub-menu. In order to
operate in console interface, the menu options shall be chosen by figures.
7.2.2 Display the Module Status
Choose ‘1’ in main menu to enter module fiber interface and copper interface status display menu. Sub-menu displays interface
status and MIB information.
7.2.3 Configure the Module Loopback
Choose ‘2’in main menu to enter loopback setting interface.

Page 19 of 25
The loopback status is depicted as follows:
CO

Remote
FPGAPHY
Remote module inside loopback:
Packets sent from remote module
copper interface will be looped inside
remote module and received/discard by
remote module copper interface
Remote module outside loopback:

received/discard by CO copper interface

module and received/discard by CO
copper interface
Note 1: when RC552-FE(A) is working under SLAVE mode, only ‘remote module inside loopback’ and ‘remote module
outside loopback’ can be performed; when working under MASTER mode, all ‘CO module inside loopback’, ‘CO module
outside loopback’, and ‘remote module outside loopback’can be performed.
Note 2: at a certain time, only one kind of loopback can be enabled. For example, after ‘outside loopback’, it must be disabled
first, and then other kind of loopback can be performed.
7.2.4 Display the Module Fault Propagation Status
Choose ‘3’in main menu to enter module fault propagation status displaying interface.

Page 20 of 25
Fx-Re (fiber interface ALS): when enabled and no local optical receiving signal is detected, shut down fiber interface
transmission. Note that this function only takes effect when remote OAM is disabled.
Fx-Tp (fiber interface to copper interface fault propagation): when enabled and no local optical receiving signal is detected,
shut down local copper interface; when remote module is manageable and copper interface to fiber interface fault propagation
is enabled and no electrical signal is detected, shut down local copper interface.
Tp-Fx (copper interface to fiber interface fault propagation): when enabled and no local electrical receiving signal is detected,
shut down local fiber interface. Note that this function only takes effect when remote OAM is disabled or remote module is
unmanageable. (Because if remote module is manageable, enabling Tp-Fx may shut down fiber interface, leading to
non-manageability to remote module)
7.2.5 FPGA Firmware Online Upgrade
Choose ‘4’in main menu to enter FPGAfirmware online upgrade interface.
