RCMS2902-2E1GE-BL Product Description
1 Overview
Raisecom Technology Co., Ltd. 2

Transmit network management information through overheads transmitted over the fiber,
realizing remote network management.

Support configuring Ethernet interface status through the NView NNM system.

Support configuring Ethernet rate limiting through the NView NNM system.

Support IEEE 802.3x-based flow control in full duplex mode and back-pressure flow
control in half-duplex mode.

Provide complete alarm indication.

Support remote power-off detection.

Support optical interface Automatic Laser Shutdown (ALS).

Support failover from the local optical interface to GE electrical interface or from remote
GE electrical interface to local GE electrical interface.

The DIP switch supports local E1 tributary bidirectional loopback and remote E1
tributary internal loopback. The NView NNM system supports local E1 tributary
internal/external/bidirectional loopback and provides embedded Bit Error Rate Tester
(BERT) for detecting links at the line and user side, helping providing and maintaining
services.

Support upgrading the card software online.
1.3 Working modes
1.3.1 Classification of working modes
The RCMS2902-2E1GE-BL supports the master mode and slave mode.

Master mode: in this mode, the RCMS2902-2E1GE-BL is used as a local card only.

Slave mode: the slave mode is further divided into the local slave mode and remote slave
mode.
− Local slave mode: the working mode of the remote card when managing the remote
through the local card
− Remote slave mode: manage the remote card directly through the RC002 Element
Management System (EMS) where the remote card is.
1.3.2 Configuring working modes
The fourth switch of the DIP switch SW1 is used to adjust the working mode of the
RCMS2902-2E1GE-BL. ON represents the slave mode and OFF indicates the NView NNM
system automatically recognizing the working mode.
For example, if the RCMS2902-2E1GE-BL is inserted into the RC002-16 chassis at local or is
inserted at the RC001-1M single-slot chassis at remote, the RCMS2902-2E1GE-BL at local
works in master mode and the one at remote works in slave mode.
1.3.3 Viewing working modes
You can view the current working mode of the RCMS2902-2E1GE-BL through the Command
Line Interface (CLI) and RC002 EMS.

Use the show info command to view the current working mode of the RCMS2902-
2E1GE-BL through CLI.
