System Overview

2.2 Switch Architecture

2.2.1 Network Management Options

7210 SAS-M CHASSIS INSTALLATION GUIDE

The 7210 SAS-M employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, that effectively doubles the bandwidth of each connection.

The 7210 SAS-M contains a comprehensive array of LEDs for at-a-glance monitoring of network and port status. It also includes a management agent that enables you to configure or monitor your switch using its CLI, or by using SNMP applications.

To manage the switch, you can make a direct connection to the console port (out-ofband Ethernet management port) or you can manage it by using a network connection (in-band SFP or XFP ports) using Telnet/SSH or SNMP-based network management software.

The management port provides a dedicated management channel that operates outside of the data transport network. This makes it possible to reconfigure or troubleshoot the switch over either a local or remote connection to the management port when using the data channel is not possible or deemed insecure.

System Overview

2.4.1 Ethernet Interfaces

2.4.1.1 Management Port

7210 SAS-M CHASSIS INSTALLATION GUIDE

The 7210 SAS-M provides 24 100/1000 SFP ports. Each port can be used for a direct connection to a subscriber’s customer premises equipment (CPE), or as an uplink to another aggregation node. The 7210 SAS-M supports 10/100/1000 Base-T copper SFPs. In addition, the 7210 SAS-M 24F 2XFP and 7210 SAS-M 24F 2XFP ETR variants support two 10G XFP ports. This port can serve as a network uplink to another aggregation node or as a direction to a subscriber's CPE.

The management port provides a dedicated management interface that is segregated from data traffic crossing the other ports.

2.4.2 Console Port

The console port uses an RJ-45 connector with serial pin assignments (see Table 11) that enables a connection to a terminal for performing switch monitoring and configuration operations. The terminal may be a PC or workstation that is running terminal emulation software, or a terminal configured as a Data Terminal Equipment (DTE) connection. A null-modem wired serial cable is supplied with the switch for connecting to this interface.

The serial port configuration requirements are as follows:

• default baud rate — 115200 bps

• character size — 8 characters

• parity — none

• stop bits — 1

• data bits — 8

• flow control — none

3HE 10089 AAAA TQZZA Edition 01 Issue: 07

Page 21

7210 SAS-M CHASSIS INSTALLATION GUIDE System Overview

2.4.3 Alarm Interface Port

The alarm interface port is a DB15 connector that supports a critical alarm output, a major alarm output, and four alarm inputs. When the system detects a critical or major issue, the CPU will cause the alarm relay to issue the alarm output and turn on the critical or major alarm LED. If you push the alarm cutoff (ACO) button, the relay will be released but the LED will stay on until the alarm is cleared.

The system signals the appropriate alarm output for the following events:

• Fan failure — critical alarm is raised.

• Power supply failure — critical alarm is raised. When the faile d power supply is removed, the critical alarm is cleared and a major alarm is raised.

• Power source failure — critical alarm is raised and the system's status LED turns amber in color and blinks.

• Chassis temperature threshold exceeded — major alarm is raised.

The system also supports four alarm inputs. The input voltage range is from 24V to 48V. If an alarm input is active, the CPU will process it, output it to the CLI, and issu e an SNMP trap. An alarm input can also be configured to issue through the appropriate alarm output pin. Please refer to the System Basics User Guide for more details on configuring the alarm inputs.

See Table 3 for the alarm interface port pin assignments.

System Overview

2.4.4.1 DC power source failure detection

7210 SAS-M CHASSIS INSTALLATION GUIDE

The 7210 SAS-M platform provides capability to detect DC power source (–48V or +24V source) failure. The 7210 SAS-M chassis allows two DC power sources to be connected to the chassis. If the system detects that the DC power source has failed, it raises a critical alarm (the Critical LED is lit and the Critical Alarm output pin is triggered) and the system's status LED turns amber and blinks. The alarm is cleared if the DC power source is restored. No user configuration is required to enable this feature. The software enables this feature automatically by detecting the capability of the hardware platform.

The system has two slots for AC or DC power supplies. It associates the DC power supply in the top slot with power source feed A (–48V or +24V Ret-A on the chassis) and the DC power supply in the bottom slot with power source feed B (–48V or +24VRetB on the chassis). The system detects the failure of power source feed A only if the DC power supply is plugged into the top slot. Similarly, the system detects the failure of power source feed B only if the DC power supply is plugged into the bottom slot. The trap message generated by the system indica tes that there was an input failure for the power supply associated with the power input feed that failed.

Note:

• New traps must be explicitly enabled by the user and are suppressed by default.

• The power feeds are summed up internally before feeding the power supply units. Therefore, the DC power supply units will output power even if only one of the power source feeds are available.

• Please refer to the release notes to determine which software release supports this feature.

Table 5 lists the conditions under which the system detects a power source failure.

7210 SAS-M CHASSIS INSTALLATION GUIDE

6.4 In-Band Access

You can access the management agent in the switch from anywhere within the attached network using Telnet or network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway.

If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

Note: The management agent can a ccept up to seven simultaneous T elnet sessions. If the maximum number of sessions already exists, an additional Telnet connection will not be able to log in to the system.

9.1 Alarm Port Pin Assignments

The alarm interface port is a DB-15 connector that supports a critical alarm output, a major alarm output, and four alarm inputs. When your system has a critical or major alarm, the CPU will cause the alarm relay to issue the alarm output and turn on the critical or major LED. If you push the alarm cut off (ACO) button, the relay will be released but the LED will stay on until the alarm is cleared.

Figure 16 DB-15 Alarm Connector

7210 SAS-M CHASSIS INSTALLATION GUIDE

The system signals the appropriate alarm output for the following events:

• Fan failure — critical alarm is raised.

• One power module failure — critical alarm is raised. The critical alarm is cleared and a major alarm is raised if the failed power supply is removed.

• Chassis temperature threshold exceeded — major alarm is raised.

The system also supports four alarm inputs. The input voltage range is from 24V to 48V. If an alarm input is active, the CPU will process it, output it to the CLI, and issu e an SNMP trap. An alarm input can also be configured to drive the appropriate alarm output pin. Please refer the System Basics user guide for more details on configuring the alarm inputs.

7210 SAS-M CHASSIS INSTALLATION GUIDE Installation Site Assessment

10 Installation Site Assessment

Before installing equipment at a site, the characteristics of the site should be considered to determine whether they will adversely affect the reliability of the equipment. The following section discusses some of the site factors to consider prior to deploying equipment.

10.1 Geographical Location

Different geographical locations carry different risk factors. For example, coastal installations with prevailing winds from the sea may be affected by Airborne Sea Salt Particles (ASSP), which can be carried many kilometers inland. As well, installations near ancient seabeds that have very high levels of salt in the soil may be affected by ASSP during windy drought conditions. Mountainous regions near coasts cause unique fog conditions. High humidity environments often cross dew point thresholds at night.

Consider whether the installation site is in an area that has the potential to experience any of the following seasonal influences: hurricanes, cyclones, tidal or river flooding, recent volcanic activity, or forest fires.

Examine the local surrounding environment of the installation site for proximity to possible sources of contaminants that may cause or accelerate corrosion, especially in the presence of high humidity.

Possible sources of contaminants include: landfills, fertilizer manufactu ring, farming, sewage, geothermal activity, swamps or marshes, oceans, ancient seabeds, power generation, automotive and diesel combustion, fossil fuel processing, cement plants, construction sites, steel blast furnaces, steel electric furnaces, coke plants, pulp manufacturing, chlorine plants, rubber manufacturing, paint manufacturing, aluminum manufacturing, ore smelting, tobacco smoke, and battery manufacturing.

If there is any uncertainty surrounding the concentration of various contaminants at the installation site, then Corrosion Classification Coupons may be used to classify the severity of the environment according to the standard ISA 71.04

Issue: 07 3HE 10089 AAAA TQZZA Edition 01 87

Page 84

Installation Site Assessment

10.2 Installation Site Type

The site must provide the appropriate environment for the installed equipment. This usually involves controlling ingress of contaminants and ensuring that humidity remains as low as possible.

Installations are typically in a hut, parking garage, room, or cabinet. Installation in data centers or telecom centers do not usually have high pollution levels but could still have high humidity levels.

10.2.1 Room

Is the room connected to the heating, ventilation, and air con ditioning (HVAC) system of the building? What protection is there to prevent ingress of dust, pollution, and humidity? To seal the environment properly, ensure that any doors, windows, vents, holes, or conduits are sealed or gasketed appropriately to ensure that the HVAC system can control the environment. These must be checked as part of routine site maintenance.

7210 SAS-M CHASSIS INSTALLATION GUIDE

If outside air is brought in for ventilation, does it pass through a filter? What is the type and rating of the filter? Filters can help but the type of filter must be appropriate for the pollutants you are trying to exclude. For example, a standard fiberglass type air filter only prevents large debris and dirt from entering, but will do nothing to prevent entry of small particles (such as ASSP), humid air or gaseous contaminants. It is important to understand the local conditions and consider what type of filtering is most appropriate. Minimum Efficiency Reporting Value (MERV) charts may serve as a good source to understand particle sizes and filter options

One simple yet effective way to keep pollutants out is to ensure that positive pressure is maintained inside the room or cabinet as compared to the outside by having fans blowing properly filtered air into the room.

Does the site have an air conditioner or dehumidifier? Is the rating and capacity adequate for the space? Where does the dehumidifier or air conditioner water drainage go?

Humidity reduction is one of the key elements in corrosion control. Air conditioners and dehumidifiers are recommended to reduce local relative humidity at the site. Another method is to keep the temperature in the cabinet high enough to maintain the relative humidity at less than 50%. Condensate, if allowed to stay in the site or enclosure, will evaporate over time and lead to higher relative humidity and corrosion.

Page 85

7210 SAS-M CHASSIS INSTALLATION GUIDE Installation Site Assessment

10.2.2 Cabinet

There are 3 major classifications of cabinets.

• Direct Air Cooled (DAC) cabinets bring air into the cabinet to cool the equipment. DAC cabinets may or may not be filtered. Unfiltered air intake and exhaust is not recommended since issues will occur if unfiltered air is allowed into the cabinet. The ideal filter is a hydrophobic filter (GORE) since it filters particles smaller than 1 micron. Hydrophobic filters will prevent passage of water droplets but still allow water vapor to pass. Some chemical pollutants may require carbon or other types of filters particularly suited to the type of pollution.

• Heat Exchange (HEX) cabinets use a sealed cabinet and a heat exchanger to withdraw heat from the cabinet interior without bringing outside air into the cabinet. This results in no contamination influx and low humidity within the cabinet.

• Air Conditioned (AC) cabinets use a mechanical or Thermal Electric Cooling (TEC) refrigeration unit to handle higher levels of heat in high-power installations. AC implementation is similar to HEX since the cabinet should be sealed. Proper AC implementation should never allow unfiltered air into the cabinet interior.

10.3 Site Influences

Is backup power generation located in the same area as the communications equipment? Are batteries located in the same area as the equipment?

Backup generators that are located in the same enclosed area as the communications equipment may cause a great deal of site pollution, such as nitrous oxides and hydrogen sulphides, which can be detrimental to the long-term reliability and performance of equipment. A best practice is to house motor generator sets in a separate enclosure from the communications equipment. Batteries will out-gas during charge and discharge cycles. These gases are very corrosive and may also be explosive in sufficient concentration. Batteries should always be housed in a properly vented enclosure or compartment, separate from the communications equipment.

Is the equipment located above the water grade? Is there adequate water drainage and leak controls?

Issue: 07 3HE 10089 AAAA TQZZA Edition 01 89

Page 86

Installation Site Assessment

Many areas are prone to flooding during rainy season or spring thaws, and it is important for the site to be located above typically an ticipated flood levels, or to have sump pumps to keep the installation site dry. Drainage with a back flow preventer should be installed if the site has provision for water sources, such as cooling towers.

What protection is there to prevent entry of insects, pests, and vermin? Pests and vermin such as insects, mice, and spiders prefer warm, sheltered areas.

All entries into the enclosure or shelter should be appropriately sealed and regularly maintained.

10.4 Site Assessment Checklists

The following site assessment checklists are intended to act as a tool in assessing the potential risks that must be managed at an installation site. The checklists are not intended to provide an exhaustive list of all risk factors, but rather to indicate some of the most common risks.

7210 SAS-M CHASSIS INSTALLATION GUIDE

The first two checklists indicate environmental factors that may result in malfunctioning or failing equipment if the installation site is not appropriately deployed and maintained to counteract the detrimental effects of the environment. For each risk factor that is present, you must consider how to best design the installation site to avoid the negative effects of the risk factor. For the final checklist, any question that is answered in the negative indicates that measures must be taken to correct the installation site appropriately to reduce the risk of equipment damage.

10.4.1 Seasonal Influences

Is the installation site in an area with the potential to experience any of these seasonal influences?
