1.6 Cabinet RoutingOverview

The cabinet outlet falls into the micro coaxial cable, optical fiber, Ethernet cables, and trunkcables, and other cables. The routing mode of cables is different from that of optical fibers.

Fiber Routing

For the convenience and good-looking of shelf-routing, optical fibers, while passing therouting sub-rack under each shelf, are put into the routing trough in the front and led toboth sides of the cabinet to be further led out of the cabinet.

Figure 1-15 shows the optical fiber routing sub-rack.

Figure 1-15 Fiber Routing Sub-Rack

Power Cable Routing

The power cable is taken out from the rear board panel. Then it goes downwards to passthrough the plugging/unplugging space of the rear board, where it is bundled to the rearhorizontal routing sub-rack. Finally, it enters the vertical routing trough from both sides,and then goes out of the cabinet.

Figure 1-16 shows the routing of rear outlets.

6.1 Alarm System ComponentsDescription

The alarm system enables users to learn the faults occurring to devices at any time. If adevice is faulty or runs improperly, it sends alarm information to the alarm server that notonly presents the current or history alarms but also forwards alarms to the alarm box in realtime. The alarm box generates sounds or lights to prompt the received alarms of differentlevels and forwards alarm information to preset mobile phone number if necessary.

Components

The alarm system consists of two components, namely the alarm server (generally it is anOMM server) and the alarm box, as shown in Figure 6-1.

Figure 6-1 Alarm System

l The alarm server allows users to determine the levels of alarms to be forwarded to thealarm box as well as the mobile phone number to which the alarm box sends alarmshort messages.

l The alarm server transfers alarm messages to the alarm box through the TCP/IPprotocol. The mobile phone module of the alarm box sends alarms to the specifiedmobile number through short messages.

6-1



l Alarms are not only presented on the LCD screen of the alarm box but also promptedby the alarm indicator, alarm server indicator, and sounds.

6.2 Alarm Box FunctionsDescription

The alarm box is connected with an alarm server through HUB or a layer-2 switch. Thealarm box presents different levels of alarm data sent from the server in various ways, forexample, on the LCD screen, through indicators, and by generating sounds.

Functions

l Alarm short message sending: The alarm server can be configured to interact with thein-built mobile phone module of the alarm box, enabling the alarm box to send alarmshort messages to the specified mobile number of a maintainer. The alarm box sendsalarm short messages based on severity of alarms to CDMA or GSM subscribers(however, CDMA and GSM cannot be supported simultaneously).

l Sound prompt: The in-built speaker produces voice or buzzer alarms to prompt thereceived alarms and the alarm levels.

l Alarm indicator: The four alarm levels are represented by different colors, namely,yellow, orange, blue, and red (listed from high to low).

l Alarm server indicator: The alarm box panel provides 10 alarm server indicatorsrepresenting 10 group of alarm servers (generally it is recommended that oneindicator represent one server). Each indicator shows the link status and the alarmstatus for a specific group of server servers.

l LCD display: The alarm information sent from the alarm server is displayed on theLCD screen of the alarm box. Moreover, the alarm box menu and keys on the panelare available to configure the working parameters, for example, the IP address, UDPport, key tone control, and backlight control.

l Remote deployment: An alarm server can be connected to both local alarm boxes (inthe same network section with the alarm server) but also the remote alarm boxes indifferent network sections by configuring routing information in the alarm box. Remotedeployment allows more flexible usages of alarm boxes. For example, the alarm boxcan be deployed in the office rather than in the equipment room.

l Multi-office-in-one: Up to 128 alarm servers can be configured on an alarm box,and up to 10 groups of alarm servers can be simultaneously connected to an alarmbox. The alarm servers may reside in different network segments, and therefore themulti-office-in-one function is employed together with the remote deployment function.

l Cross-VLAN alarming: The alarm box can be simultaneously connected to alarmservers from different VLANs. In this scenario, a layer-2 switch rather than a layer-3device is deployed to achieve VLAN isolation, reducing the networking cost.

l Network storm detection and alarming: Thresholds can be configured to detect thenetwork status and avoid network congestion caused by data broadcast.

6-2


Chapter 6 Integrated Alarm Box

l Group-based alarm acknowledgement: Alarms can be acknowledged on a per-groupbasis as alarm servers can be classified into groups, and each group of alarm serversis represented by an alarm server indicator.

l Alarm statistics query: The alarm box can show the statistics of alarms reported byeach alarm server on the LCD screen.

l Permanent mute: Alarm prompts can be muted based on the alarm severity.l Remote access: The alarm box supports Telnet-based remote access. Users

can telnet the alarm box to configure relevant parameters by using man-machinecommands. The alarm box supports the configurations concerning alarm servers,routing, VLAN, short message transfer, system time, and so on.

6.3 Integrated Alarm Box PrincipleSchematic Diagram

Figure 6-2 shows the principle of the integrated alarm box.

Figure 6-2 Integrated Alarm Box Principles

Principle Description

The integrated alarm box is composed of the ALMP, ALMK and ALML boards.

l ALML board: Includes alarm indicators with four levels (in 4 colors) and correspondingdrive circuits.

6-3



l ALMK board: Includes keys, adaptive socket of LCD module, backlight power supplyfor LCD module to work normally, and negative circuit for LCD display. This boardand LCD module can be removed if the LCD is not necessary.

l ALMP board: Main processor card completes alarm information receiving andprocessing, generates and transmits audio & visual alarms. It consists of controlcircuit, interface circuit, and acts as a mother board for connection of the ALML andALMK boards.
