2.2 Switch Architecture

The 7210 SAS-T employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports.

2.2.1 Network Management Options

The 7210 SAS-T 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 the 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 (such as the Nokia 5620 SAM).

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 access using the data channel is not possible or deemed insecure.

2.3 Features

The 7210 SAS-T includes the following features:

• all connections front facing

• wire speed, non-blocking, service-aware Layer 2 switch

• 12 100/1000 fiber-optic SFP ports

System Overview

2.4.1 Ethernet Interfaces

2.4.1.1 Management Port

7210 SAS-T CHASSIS INSTALLATION GUIDE

The 7210 SAS-T provides 12 100/1000 fiber-optic 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-T supports 10/100/1000 Base-T copper SFPs. The 7210 SAS-T also provides 10 10/100/1000 Base-T fixed copper ports. There are four XFP ports, which provide 10G redundant network uplinks to another aggregation node or 10G redundant connectivity to a subscriber's CPE. In addition, the 7210 SAS-T ETR variant supports four PoE and PoE+ ports.

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 10) 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.

Note: The Console port LED is not used.

The serial port configuration requirements are as follows:

• Default baud rate — 115200 bps

• Character size — 8 characters

• Parity — none

• Stop bit — 1

• Data bits — 8

• Flow control — none

Page 21

7210 SAS-T CHASSIS INSTALLATION GUIDE System Overview

2.4.3 BITS Port

A Building Integrated Timing Supply (BITS) is a clock in a central office that supplies a common frequency reference to all synchronous network elements in that office. The BITS port on CCM front panel allows the node to be connecte d to such a timing supply unit. The port uses an RJ-48C connector and has both input and output signals. An appropriate cable must be used to break out the input and output signals and to provide connection to the timing supply unit. The port supports both T1 and E1 signaling formats. For pin assignments, see Table 17.

2.4.4 Alarm Interface Port

The alarm interface port is a DB-15 connector that supports a critical alarm output, a major alarm output, and four alarm inputs. When the 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.

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

• Fan failure — critical alarm is raised.

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

• On power source failure — critical alarm is raised.

• 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 signal the appropriate alarm output pin. Optionally, the 7210 SAS-T can power the device connected to the power alarm input pin. Please see section 9 for more details. Please refer to the System Basics User Guide for more details on configuring the alarm inputs.

RTN refers to the negative side of the alarm In connections floating power supply. If an external power supply is used to source the voltage for ALARM_IN1_EXT_+, ALARM_IN2_EXT_+, ALARM_IN3_EXT_+, or ALARM_IN4_EXT_+, the external power supply negative rail must not be connected to th e chassis ground and it should be 18 to 50 VDC at 100 mA.

7210 SAS-T CHASSIS INSTALLATION GUIDE System Overview

Note:

• You must use AC and/or DC power modules with the 7210 SAS-T. AC and DC power supplies can be used simultaneously.

• The 7210 SAS-T ETR variant must use the 200W power supply when PoE or PoE+ ports are enabled to supply power to exter nal devices. A maximum of up to 60W power is available for use by connected PoE and PoE+ devices.

• The 7210 SAS-T ETR variant must use a power module which supports extended temperature range.

• The +24V DC power module must not be used simultaneously with the –48V DC power supply.

2.4.5.1 DC power source failure detection

The 7210 SAS-T provides the capability to detect DC power source (–48V or +24V source) failure. The 7210 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). The alarm is cleared if the DC power source is restored. There is no user configuration required to enable this feature. The software enables this feature automatically by detecting the capability of the hardware platform.

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

Note: The power feeds are summed up internally before feeding the power supply units. Hence, both DC power modules will output power even if only one power source feed is available.

Table 3 lists the conditions under which the system detects a power source failure.

3 Installing the Chassis

This chapter describes site preparation and installation of the 7210 SAS-T and includes the following sections:

• Site Preparation, section 3.1

• Installing the Switch, section 3.2

3.1 Site Preparation

3.1.1 Selecting a Site

Mount the 7210 SAS-T in a standard 19-inch equipment rack or on a flat surface. When you mount the switch on a flat surface, ensure that the four rubber feet are installed on the bottom of the box.

The site should be a weather-protected and temperature-controlled location, and should include the following criteria:

• Maintain site temperature within 32 to 122ºF (0 to 50ºC) and its humidity within 5 to 95%, non-condensing for the 7210 SAS-T. For the 7210 SAS-T ETR variant, maintain site temperature within –49 to 149ºF (–40 to 65ºC).

• Provide adequate space on the front and two sides of the unit to enable servicing and proper air flow.

• Ensure a secure environment in which only authorized and trained service personnel are allowed to service the unit (IEC 60950 safety requirement).

For more information about installation site assessment, see section 10.

3.1.2 Installation Locations

Warning: Follow the equipment rack manufacturer’s instructions for proper rack installation.

Failure to comply with the requirements and the location requirements outlined in this section may impede proper airflow and may result in the system overheating.

Edition: 08 3HE 10091 AAAA TQZZA Edition 01 35

Installing the Chassis

7210 SAS-T CHASSIS INSTALLATION GUIDE

The 7210 SAS-T is intended to be installed in facilities that provide weather protection and an extended temperature-controlled environment. The 7210 SAS-T is not intended for installation outdoors.

The 7210 SAS-T is designed to work in an environment equivalent to a modern office building, where protection is provided from contaminants including mold growth, precipitation, volatile or corrosive chemicals, hygroscopic dust, insects, pests, or vermin entering the product.

When a 7210 SAS-T is installed in an outside plant, such as a cell site, hut, cabinet, or outside plant enclosure, it must be installed in an environment where, except during installation and servicing, the compartment is sealed or properly filtered.

The product must be protected from ingress of contaminants such as outside air, conductive pollution, volatile or corrosive elements (for example, salt-laden air), hygroscopic dust, insects, pests, or vermin.

The humidity levels in the cabinet must be controlled to ensure a relative humidity level between 15% and 85% (non-condensing) with short-term levels of 5% to 95% (non-condensing). (Short-term is a period of less than 96 consecutive hours and a total of no more than 15 days per year. This is equivalent to 360 hours per year, with short-term periods occurring no more than 15 times per year.) The dew point threshold in the cabinet must not be crossed.

Protection is typically achieved by deploying the product in a cabinet that is sealed and is provided either with air-to-air heat exchangers or with air-conditioning and/or heaters as required for the local climate. If the cabinet is the type that allows outside air to ventilate the cabinet, it must have Hydrophobic Membrane filters, at the air inlet and air exit, with all other parts properly sealed against outside contaminants and moisture.

Typically, cabinets that comply with Telcordia GR-487, Generic Requirements for Electronic Equipment Cabinets, provide this level of protection.

The ambient air temperature must be within the specifications defined in section 7.1. For proper thermal performance, the following conditions must be met:

• For seismic applications, the rack must be a Telect Global Seismic Frame (GS series).

• The rail mounting holes in the equipment rack must align with the mounting holes on the chassis mounting brackets. The 7210 SAS-T mounting brackets are factory-installed for a NEBS mount in a 19-inch rack.

7210 SAS-T CHASSIS INSTALLATION GUIDE Installing the Chassis

Required tools and hardware:

• #2 Phillips screwdriver

• Flathead screwdriver

• Anti-static bags, mats, and packaging

• ESD wrist strap

3.1.3 Ethernet Cabling

To ensure proper operation when installing switches in to a network, make sure that the cables are suitable for 100/1000 fiber-optic or 10/100/1000 Base-T copper operation, as appropriate. Ensure that the installation complies with the following guidelines:

• Cable type: shielded twisted pair (STP) cables for GR-1089 locations; Category 3 or better for 10 Base-T, Category 5 or better for 100 Base-TX, and Category 5, 5e or 6 for 1000 Base-T.

• Make sure that the cables are not damaged and that the RJ-45 connectors are connected securely.

• For inter-building connection use fiber-optic cables.

• Copper ports are suitable for connection to intra-building or unexposed wiring or cabling, and are intended for indoor applications only. The intra-building ports of the equipment must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

• Avoid installing copper cables close to strong electromagnetic fields generated by electric generators, elevator engines, or other similar heavy electric machines.

• Make sure you only use SFPs that are supported by Nokia.

3.1.4 Equipment Checklist

After unpacking the switch, check the contents to make sure all the components are present. Before installation, make sure you have all the necessary equipment.

the LEDs on both modules are lit as indicated in step 4.

Step 6. Ensure that PS1 and PS2 LEDs on the 7210 SAS-T front panel are lit if both

primary and redundant power supplies have been installed.

The 7210 SAS-T chassis supports the –48V and +24V DC power modules. Hence, the steps below are applicable for either the –48V or the +24V DC power modules.

Note: Below the DC power entry block is an additional ch assis ground point for at taching a DC power chassis ground if required by local electrical codes. The ground point should be connected with an M4 screw and a terminal lug as specified by local electrical codes.

Danger: Before wiring the DC plug or connecting power to the switch, en sure that power to the feed lines is turned off at the supply circuit breaker or disconnected from the power bus.

Caution: Do not install a –48V and a +24V AC power module in to a 7210 SAS-T chassis the same time.

Note:

• An additional chassis ground point is located below the DC power entry block, for attaching a DC power chassis ground if required by local electrical codes. The ground point should be connected with an M4 screw and a terminal lug as specified by local electrical codes.

• If a single power feed (either A or B) is connected to provide power to the system, it supplies power to both of the power modules if two modules are plugged in. The DC power feeds, A and B, are internally bridged using a diode.

• To provide adequate circuit protection between the DC power supply and the switch, all intermediate wiring and circuitry should be rated to carry a load at least two times the maximum rating for this switch (see section 7).

To connect DC power: Step 1. Before a VDC power supply module can be used, you must connect an

external DC power source to the DC power connection on the left side of the front panel (see Figure 1). The external DC power supply must be between

-36 to -72 VDC, and protected with a circuit breaker.

Step 2. The wiring between the DC power supply and the switch must be stranded

copper wire within the range of 16 to 20 AWG in accordance with local electrical codes.

Step 3. Connect the VDC power feed using the VDC input and RETA/B (return)

lines for power source A and B, respectively. Insert the wires in to the DC input plug (using a small flat-tip screwdriver). Color code the wiring according to local standards to ensure that the input power and ground lines can be easily distinguished.

Figure 16 illustrates how to connect a –48 VDC power source to the

chassis:

Danger: If the power leads are plugged in to the wrong holes, the power supply will not work properly and may damage the switch.

Step 4. After the power source is turned on, set the power butt on on the front of the

power supply module to the ON position (marked “—”).

Step 5. Check the LEDs on the power supply module as the switch is powered on

to verify that the –48V/+24V LED indicating external power status is on, and that the +12V LED indicating internal power conversion is on. If not, recheck the power supply and power cable connections at the supply source and at power supply module.

Step 6. If you have installed both a primary and redundant power supply module,

verify that the LEDs on both modules are lit as indicated in the preceding step.

Step 7. Ensure that PS1 and PS2 LEDs on the 7210 SAS-T front panel are lit if both

the primary and the redundant power supply has been plugged in.

5.1 Initializing the System and Downloading Software

The 7210 SAS-T ships with bootloader and TiMOS on the compact flash memory device (cf). When the system is powered up for the first time, the bootloader will attempt an auto-init procedure (see the System Basics Guide for more information). However, the auto-init can be interrupted and the boot operation controlled manually.

Note: By default, 7210 SAS platforms attempt the autoinit procedure unless interrupted by the user and forced to use TiMOS from flash memory.

5.1.1 Booting in the Lab

There are several ways to boot the 7210 SAS-T from the network. User can choose to boot the device using one of the following options:

• Using the USB port

• Using the external compact flash card (cf2:\)

• Using the image shipped on the internal flash (cf1:\)

• Using the network to load the image and boot the device

The subsequent sections describe how to boot the device using either of the options listed above.

7210 SAS-T CHASSIS INSTALLATION GUIDE Troubleshooting

6.3 Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the othe r components are functioning properly.

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 into the system.

9 Alarm Pin Assignments

This appendix contains Alarm port pin assignments.

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 a critical or major alarm condition occurs, 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 20 DB-15 Alarm Connector

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

• Fan failure — critical alarm is raised.

• One power supply 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.

See Table 18 for the alarm interface port pin assignments.

RTN refers to the negative side of the alarm input connections floating power supply. If an external power supply is used to source the voltage for ALARM_IN1_EXT, ALARM_IN2_EXT, ALARM_IN3_EXT, and ALARM_IN4_EXT, its negative rail must not be connected to chassis ground and it should be 18 to 50 VDC at 100 mA.

When using the internal isolated 24 VDC power supply on pin 4 of the DB-15 connector, Alarm RTN pins must be connected to chassis ground. The metal shell of the alarm plug may be used as a chassis ground connection for the internal +24V supply providing that the plug mounting (hold down) screws are firmly attached to the 7210SAS-T alarm connector.

Major and Critical alarm dry relay contact outputs are provided on pins 3,10,11 and 1,2,9. These reflect the Major and Critical alarms output by the box and can be manually cleared by pressing the ACO button.

The four alarm inputs are customer configurable to monitor alarms provided by additional equipment. These inputs require either using the voltage source provided through pin 4 of the DB-15 connector or a separate isolated DC power supply between 18 to 50 VDC at 100 mA. If an external power source is used its outputs must be isolated from chassis ground; for example, do not connect the alarm power supply return to the chassis or rack ground in this scenario. See the 7210 SAS-T software configuration guide for more information.

7210 SAS-T 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

Edition: 08 3HE 10091 AAAA TQZZA Edition 01 95

Page 96

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-T 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 97

7210 SAS-T 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?

Edition: 08 3HE 10091 AAAA TQZZA Edition 01 97

Page 98

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-T 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.
