Warning:
• ESD damage can occur if components are mishandled. The chassis and
equipment rack must be properly grounded. A typical grounding point is one
of the ground studs on the chassis or a properly grounded rack or work
bench.
• Always wear an ESD-preventive wrist or ankle strap connected to a nearby
ground point that is connected to the site grounding point when workin g on
the
chassis or the 100W High Voltage Power Supply.
The risk of damage to an ESD-sensitive device is reduced considerably after
assembly in a circuit designed to protect sensitive components; however, the
following basic precautions should be taken to reduce ESD to harmless levels.
• Handle all units as if they contained ESD-sensitive devices unless they are
known not to contain ESD-sensitive parts.
• Wear an anti-static ESD strap on your wrist or heel prior to and while touching
or handling units containing ESD-sensitive devices.
• For surfaces with resistance to ground in excess of 100 MΩ, such as ordinary
tile, either cover them with properly grounded static dissipative runners or
wax them with a static dissipative wax.
• Store (even temporarily), pack, and ship units in anti-static bags or
containers.

The 7210 SAS-R12 employs a wire-speed, non-blocking switching fabric that
permits simultaneous wire-speed transport of multiple packets at low latency on all
ports utilizing the following common components:
• SF/CPM—a CPU for control-plane tasks paired with a switch fabric including
control plane CPU, CPM packet processor, and switch fabric.
• IMM—packet processor data-plane forwarding functionality including
data-plane packet processor and Ethernet interfaces
• Switch fabric—connectivity between IMMs, and between IMMs and

SAS-R12 CHASSIS INSTALLATION GUIDE System Overview
3.3 Network Management Options
The 7210 SAS-R12 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 the CLI, or by using SNMP
applications.
To manage the 7210 SAS-R12, you can make a direct connection to the console
ports on the SF/CPM (Figure 8), out-of-band Ethernet management ports, or you can
manage it by using a network connection using Telnet/SSH or SNMP-based network
management software (such as ALU 5620 SAM).
The management ports provide 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.
3.3.1 Connectivity
The 7210 SAS-R12 IMMs offers the following connectivity options:
• 1G fiber-optic SFP (small form factor pluggable) or 1G fiber-optic CSFP
(compact small form factor pluggable) ports
• 10G SFP+ (enhanced small form-factor pluggable) ports
• 100G CFP4 ports
IEEE 802.3-2005 Gigabit Ethernet (GE), and Ten-Gigabit compliance ensures
compatibility with standards-based network cards and switches from any vendor.
IEEE 802.3bm (2015) and IEEE 802.3ba-2010 Gigabit Ethernet (GE), and
100-Gigabit compliance ensures compatibility with standards-based network cards
and switches from any vendor.

SAS-R12 CHASSIS INSTALLATION GUIDE
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. Table 36 for pin assignments.
The 7210 SAS-R12 OMC port supports use and management of the 1830 VWM
flexible CWDM clip-on device, see Figure 9.1830 VWM is a cost-optimized managed
CWDM passive device, which is an add-on shelf/NE and provides CWDM extension
to devices that do not have built-in CWDM capabilities. Table 37 for pin assignments.
For more information about 1830 VWM, refer to 7210 SAS M, T, X, R6, R12 OS Basic
System Configuration Guide and 1830 Versatile WDM Module (VWM) Product
Information and Planning Guide.

3.4.2.5 Alarm Interface Port
The alarm interface port is a D-type 15-pin connector (see Figure 52) 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
corresponding critical or major 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.

Page 43
SAS-R12 CHASSIS INSTALLATION GUIDE System Overview
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 generated.
• Chassis temperature threshold exceeded—major alarm is raised.
The system supports four alarm inputs. To process alarm inputs, you must configure
the alarm to enable processing and also specify the action to take when the alarm
input is active. If an alarm input is active, the CPU will process it, output it to the CLI,
and issue an SNMP trap. An alarm input can also be configured to signal the
appropriate alarm output pin. Additionally an option is provided to power the device
connected to the power alarm input pin. For more information about alarm inputs and
interface port pin assignments, see section 11.1. For more information about alarm
input configuration, refer to 7210 SAS M, T, X, R6, R12 OS Basic System
Configuration Guide.
3.4.2.6 USB Port
The USB port provides support for USB storage devices and can be used to store
accounting records, logs, and TiMOS images (uf1:/). The list of supported USB
devices is provided in the release notes.
3.4.2.7 Compact Flash Memory Card Slot
The compact flash memory card slot, labeled as CF2 on the SF/CPM, accepts a
compact flash card. It can be used to store accounting records, logs, and TiMOS
images. It can also be used to boot the system. Please refer to the 7210 SAS-R12
release notes for detailed information on the supported compact flash storage
devices supported on the 7210 SAS-R12.

3.4.3.2 AC to DC Rectifiers
SAS-R12 CHASSIS INSTALLATION GUIDE
AC to DC rectifiers (Figure 12) change 120/240V AC power to -48 Vdc power.
Each AC power shelf (Figure 13) can accommodate up to four AC to DC rectifiers
that plug into a common power backplane in the AC-input power shelf.
For the 7210 SAS-R12 chassis, four rectifiers are required with two for each feed if
using 90-154 Vac input voltage. Two rectifiers are required with one for each feed if
using 180-264 Vac input voltage.
The AC to DC rectifiers in each feed of the power shelf provide automatic loadsharing. When a rectifier is removed, the remaining rectifiers adjust to fulfill the power
requirements and maintain uninterrupted system power.

Figure 13 AC Rectifier Shelf
For the AC power shelf, when the AC input voltage is 180-264 Vac the maximum
rated output power for each feed is 5000 W with two rectifiers. When the AC input
voltage is 90-154 Vac, the maximum rated output power for each feed is 3000 W with
two rectifiers.
The AC to DC rectifiers in the AC power shelf are hot-swappable. You can remove
or replace a power module while the system is operating without affecting system
operation.
The power source (outlet) should be located near the equipment rack and be easily
accessible.
For maximum redundancy, connect each AC-input power module to a separate AC
power feed.
Each AC to DC rectifier includes two LEDs that indicate power and failure conditions.
Table 7 describes LED behavior.

The 1-port 100GE CFP4 IMMv3 (imm-sas-c) delivers 100Gb/s per slot performance.
Note:
• From release 7210 SAS 9.0R6, the 7210 SAS-R12 platform supports IMMv3 cards
(imm-sas-c).
• Before using IMMv3 (imm-sas-c) cards, you must configure the system for IMMv3 cards
using the command: configure> system> chassis> allow-imm-family imm-sas-r-c,
followed by a reboot of the node to allow the system to correctly initialize when using
IMMv3 cards.
• The IMMv2 (imm-sas-b) cards and IMMv3 (imm-sas-c) cards can co-exist in a single
chassis. To configure the system for both IMMv2 (imm-sas-b) cards and IMMv3
(imm-sas-c) cards, use the CLI command: configure> system> chassis> allow-immfamily
• For 100G bandwidth, two SF/CPMs must be installed and provisioned for full 100Gb/s
bandwidth. With a single SF/CPM installed in the chassis, 60Gb/s of bandwidth is
available.
• System scaling of the functions supported when a mix of IMMv2 and IMMv3 are in use
in the chassis, is the lower of the scaling supported by each of the cards. Please refer
to the scaling guide or talk to your Nokia representative for more information.

Each 7210 SAS-R12 supports up to twelve IMMs, two SF/CPM, and two DC PEMs.
Each system is shipped with impedance panels installed in the component slots,
rack-mounting brackets, and a console cable. Impedance panels are required in
empty slots to ensure proper airflow path within the chassis, to control
electromagnetic interference, and to prevent dust accumulation.
Warning: Remove impedance panels only when replacing with live card assemblies.
4.1.1 Selecting a Site
Mount the chassis in a standard 19-inch equipment rack, or an European
Telecommunications Standards Institute (ETSI) rack; see section 4.4.3.
The site should be a weather-protected and temperature-controlled location, and
should include the following criteria:
Edition: 06 3HE 10320 AAAA TQZZA 67
Page 67
Site Preparation and Installation
• Maintain site temperature within 32 to 122ºF (0 to 50ºC) and humidity within
5 to 93%, non-condensing for the 7210 SAS-R12.
• 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 13.
4.1.2 Ethernet Cabling
To ensure proper operation when installing chassis into a network, make sure that
the cables are suitable for 10/100/1000 fiber-optic operation, as appropriate. Make
sure 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.
SAS-R12 CHASSIS INSTALLATION GUIDE
• 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.

Site Preparation and Installation
Note:
• Prepare the equipment rack and site before installing the switch. Plan the switch
placement near the power sources and network interface connections.
• Remove paint and other nonconductive coatings from surfaces between the mounting
hardware and the rack. Clean surfaces with an anti-oxidant before you install the switch
in the rack. The path between the chassis and the rack must be of sufficiently low
impedance to facilitate the operation of any circuit over-current protection and it must
be capable of safely conducting any fault current likely to be imposed.
• The chassis is suitable for connection to a CBN grounding system.
• The chassis is intended to be located in a Central Office.
• An empty 7210 SAS-R12 chassis weighs approximately 34.1 lbs (15.47 kg). A fully
equipped chassis weighs approximately 64.9 lbs (17.74 kg).
• Use a hand cart or mechanical lift to lift or move the switch.
• Always install the heaviest equipment on the bottom of the rack to keep the center of
gravity of the equipment rack as low as possible.
• To provide necessary stability, ensure that the equipment rack is bolted to the floor.
Ceiling brackets are useful to provide additional stability.
• The equipment rack must be properly grounded.
• Install components after the chassis is installed in the rack.
• Maintain a clearance of at least 12 in. (30.48 cm) at the front of the switch to ensure
adequate room for component installation and service.
• Maintain adequate air flow to and from all equipment in the rack, ensuring that nothing
impedes with intake or exhaust air flow.
• The 7210 SAS-R12 chassis includes factory-installed rack-mounting brackets to install
in a 19-inch equipment rack. These mounting brackets are integral to the chassis. For
ETSI racks, you must use mounting bracket extenders, which can b e found in the Cable
Management and the ETSI Extension Bracket Kit, see Table 41.

4.5 Grounding the Chassis
Warning:
• Only qualified personnel should perform wiring and cabling to the system.
• All power to the equipment rack or cabinet should be disconnected before the
installation.
• You must use cables that meet local electric code requirements.
• An external circuit br ea ke r no grea te r tha n 15 A must be loca te d with in a re ad ily
accessible distance of the equipment. This is intended as the disconnect device.
• If you ground the equipment by a method other than those provided in this manual,
those means should be in compliance with all local wiring regulations and practices.
• The intra-building ports (Console, Management, OES1, OES2, Alarm, BITS1/ToD,
BITS2/ToD, 1PPS, 10MHz, and OMC) must be connected to shielded and grounded
cables at both ends.
• The intra-building ports (Console, Management, OES1, OES2, Alarm, BITS1/ToD,
BITS2/ToD, 1PPS, 10MHz, and OMC) of the equipment or sub-assembly are suitable
for connection to intrabuilding or unexposed wiring or cabling only. The intra-building
ports of the equipment or subassembly must not be metallically connected to interfaces
that connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue
6) and require isolation from the exposed OSP cabling. The addition of primary
protectors is not sufficient protection to pe rm it co nn ec tio n of th es e inte r faces
metallically to OSP wiring.
• The 7210 SAS-R12 must be grounded via a copper ground conductor. The
7210 SAS-R12 utilizes a Burndy YAZV10-2TC14 grounding lug with a wire gauge of 10
AWG that is secured to the frame and EUT by screws tightened to a torque of 58 to
68 lbf-in (6.55 to 7.68 N·m).
• All bare conductors must be coated with an appropriate antioxidant compound before
connections are made. All unplated connectors, braided strap, and bus bars must be
brought to a bright finish and then coated with an antioxidant before connecting them.
When making the primary ground connection, a star washer must be used for antirotation. When connecting the device to the rack frame, use thread-forming screws and
paint-piercing washers.
• The 7210 SAS-R12 is specified for DC-I power configurations. The battery returns must
remain isolated until they reach the main power bus.
Danger: The earth connection must not be removed unless all supply connections have
been disconnected.
The switch is suitable for installation as part of the Co mmon Bonding Network (CBN).
The switch is suitable for installation in Network Telecommunication Facilities or
locations where the NEC applies.

4.10 Installing SF/CPMs
Warning: Impedance panels are required in all empty slots to ensure pro per airflow path
within the chassis, and to control electromagnetic interference.
Note:
• Each SF/CPM module has two ejector levers which seat and release the card from the
backplane connectors.
• During installation, the ejector levers must be positioned outward and then rotated
inward to lock into place.
• The ejector levers must remain in the locked position while the card is installed in the
chassis.
Step 1. Remove the SF/CPM module from the packaging. Avoid touching board
components and connector pins. Ensure that you follow standard ESD
procedures.
Step 2. The SF/CPM must be installed in one of the middle two chassis slots
labeled
SF/CPM A or SF/CPM B.
Hold the card by the edges and then rotate the ejector levers outward
toward the faceplate.
Step 3. Align the card with the slot guides and slide inward until the locking
mechanism engages with the card cage.
Step 4. Simultaneously, rotate the ejector levers inward to lock the backplane
connectors and SF/CPM in place. If an ejector lever can not be moved to
the locked position, the card is probably not seated properly in the
backplane. Pull the card out halfway, adjust the levers, and reinsert the
card. Rotate the levers to the locked position.
Step 5. Secure the card in place by tightening the captive screws.

4.11 Installing IMMs
Warning: Impedance panels are required in all empty slots to ensure pro per airflow path
within the chassis, and to control electromagnetic interference.
Step 1. Remove the IMM from the packaging. Avoid touching board components
and connector pins. Ensure that you follow standard ESD procedures.
Step 2. Holding the IMM by the edges, align the IMM with the slot guide and slide
the IMM into the slot.
Step 3. Attach the IMM handle to the captive screws on the card.
Step 4. Using the handle, insert the IMM until the connectors are seated with the
backplane.
Step 5. Secure the IMM into place by tightening the captive screws.
