conductors only. Statement 1025
Warning
When installing
the unit, the ground connection must always be made first and disconnected
last. Statement 42
This unit is to be
installed in a restrictive access location and must be permanently grounded to
minimum 6 AWG copper ground wire.
Perform the
following procedure to ground the Cisco ASR 907 Router using a 2-hole lug and
the corresponding mounting point. Most carriers require a minimum 6 AWG ground
connection. Verify your carrier’s requirements for the ground connection.
Procedure
Step 1
If your ground
wire is insulated, use a wire-stripping tool to strip the ground wire to 0.5
inch ± 0.02 inch (12.7 mm ±0.5 mm) As shown in the figure below.
Figure 14. Stripping a Ground Wire
Step 2
Slide the open
end of your 2-hole ground lug over the exposed area of the ground wire.
Step 3
Using a
crimping tool (as specified by the ground lug manufacturer), crimp the ground

Step 4
Use a Phillips
head screwdriver to attach the 2-hole ground lug and wire assembly to the
router with the 2 pan-head Phillips head screws. For a 19-inch EIA rack, attach
the 2-hole ground lug to the rear of the router.
Step 5
Connect the
other end of the ground wire to a suitable grounding point at your site.
Installing the Fan
Tray
The fan tray is a
modular unit that provides cooling to the Cisco ASR 907 Router.
Note
Do not introduce
body parts or objects in the fan tray slot when installing or removing the fan
tray module. Exposed circuitry is an energy hazard.
Follow these steps
to install the fan tray in the chassis:
Procedure
Step 1
Orient the fan
tray so that the captive screws are on the left side of the fan tray’s front
panel. The figure below shows how to orient the fan tray.
Figure 16. Installing the Fan Tray
Step 2
Guide the fan
tray into the chassis until it is fully seated.
Caution
The fans are
exposed on the left side of the fan tray. Keep your fingers, clothing, and
jewelry away from the fans. Always handle the fan tray by the handle.
Note
When
installing the cabling to the RSPs, we recommend that you leave a service loop
of extra cabling sufficient to allow for fan tray removal.
Step 3
Secure the fan
tray to the chassis using the attached captive installation screws. The
recommended maximum torque is 5.5 in.-lb (.62 N-m).
This completes
the procedure for installing or replacing the fan tray in a Cisco ASR 907
Router.
The chassis is
shipped with a blank fan filter cover. To install the dust filter:
Procedure
Step 1
Remove the
blank fan filter cover (A907-FAN-F=) by unscrewing the captive installation
screws at the top and bottom of the dust filter frame. See the figure below.

Removing the Dust Filter
Remove the dust filter for a replacement.
Note
The dust filter is a single-use component.
Use the dust filter (A907-FAN-F) within 6 months of buying as the shelf or storage life is less than 6 months. The ideal storage
condition for a filter is a cool, dry, and dark environment. Surroundings that adversely affect the dust filter are high heat,
humidity at high temperatures, and ultraviolet light.
Dust Filter Maintenance
A periodic health check of the filter, every 3 months based on the level of dust in the environment, helps in avoiding over
clogging of the filters and provides a better life. This product's filter is used as a single-use component. If the product
is installed in a controlled environment, check and replace the filter every three months, otherwise replace the filter every
month with PID (A907-FAN-F=) or equivalent.
Removing and
Replacing the Fan Tray
The fan tray supports online insertion and removal (OIR). There is no need to power down the Cisco ASR 907 Router to remove
or replace the fan tray. However, the router will shut down if the fan tray is removed from the chassis for more than 90 seconds
at 25º C due to thermal overload condition. Approximately at 25º C the system powers back in 2 minutes.
Note
If a fan tray is removed and not replaced within the stipulated time the system will automatically power-off. If the system
is powered with PSUs other than 900W DC or 1200W AC and if the system is powered off, then the system should be completely
powered off for 30 seconds with all the PSU in the system simultaneously, and then turned on for the system to power on.
Note
Do not introduce
body parts or objects in the fan tray slot when installing or removing the fan
tray module. Exposed circuitry is an energy hazard.
Caution
The router can
stay active for up to 60 seconds if the temperature is up to 30º C. However, in
the event of an overtemperature alarm, the router can shut down in less than 60
seconds. In the event of a critical temperature alarm, the router shuts down
immediately.
Caution
To avoid
erroneous failure messages, allow at least 2 minutes for the system to
reinitialize after the fan tray has been replaced.
Follow these steps
to remove and replace the fan tray on the Cisco ASR 907 Router:
Procedure
Step 1
Using a No. 2
Phillips screwdriver or your fingers, loosen the captive installation screw
that secures the fan tray to the chassis. The figure below shows the front of
the fan tray, including the captive installation screws.
Figure 19. Detaching the Fan Tray

Step 2
Grasp the fan
tray handle with one hand and the outside of the chassis with the other hand.
The figure above shows the front of the fan tray, including the handle.
Caution
The fans are
exposed on the left side of the fan tray. Keep your fingers, clothing, and
jewelry away from the fans. Always handle the fan tray by the handle.
Step 3
Pull the fan
tray toward you no more than 1 inch to disengage it from the power receptacle
on the midplane, as shown in the figure below.
Figure 20. Fan Tray Removal
Warning
When removing the fan tray, keep your hands and
fingers away from the spinning fan blades. Let the fan blades completely stop
before you remove the fan tray. Statement 258
Step 4
Wait at least 5
seconds to allow the fans to stop spinning. Then, pull the fan tray backward
toward you and out of the chassis.
Note
As the fan
tray slides out of the chassis, support the bottom of the fan tray with one
hand and keep your other hand on the fan tray handle.
This completes
the steps for removing the fan tray from the chassis.
Note
The chassis
must not be allowed to operate without functioning fans for more than 60
seconds.
To install the
new fan tray, follow the steps in Installing the Fan Tray .
RSP Installation
Follow these steps on handling an RSP module in the Cisco ASR 907 Router:
Installing an RSP
Module
To install an RSP
module in the router chassis, perform the following steps:
Procedure
Step 1
Choose a slot
for the module. Make sure that there is enough clearance to accommodate any
equipment that will be connected to the ports on the module. If a blank module
filler plate is installed in the slot in which you plan to install the module,
remove the plate by removing its 2 Phillips pan-head screws.
Step 2
Fully open both
the ejector levers on the new module, as shown in the figure below.
Caution
To prevent
ESD damage, handle modules by carrier edges only.
Step 3
Position the
module in the slot. Make sure that you align the sides of the module with the
guides on each side of the slot, as shown in the figure below.
Figure 21. Cisco ASR
907 Router RSP Installation
Step 4
Carefully slide
the module into the slot until the EMI gasket on the module makes contact with
the module in the adjacent slot and both the ejector levers have closed to
approximately 45 degrees with respect to the module faceplate.
Caution
If the top
slot already has an RSP module installed, and you install a second RSP module
in the slot below it, be careful not to damage the EMI gasket of the bottom RSP
module against the ejector levers of the top RSP during insertion.
Step 5
While pressing
down, simultaneously close both the ejector levers to fully seat the module in
the backplane connector. The ejector levers are fully closed when they are
flush with the module faceplate.
Step 6
Tighten the two
captive installation screws on the module. The recommended maximum torque is
5.5 in.-lb (.62 N-m).
Note
Make sure that the ejector levers are fully closed before
tightening the captive installation screws.
Step 7
Verify that the
captive installation screws are tightened on all of the modules installed in
the chassis. This step ensures that the EMI gaskets on all the modules are
fully compressed in order to maximize the opening space for the new or
replacement module.
Note
If the captive installation screws are loose, the EMI gaskets
on the installed modules will push adjacent modules toward the open slot, which
reduces the size of the opening and makes it difficult to install the new
module.
Caution
Blank module
filler plates (Cisco part number A90X-RSPA-BLANK-W) should be installed in any
empty chassis slots to keep dust out of the chassis and to maintain consistent
airflow through the chassis.
Note
When installing the cabling to an RSP, we recommend that you
leave a service loop of extra cabling sufficient to allow for fan tray removal.
Note
Close all unused RJ-45 and USB ports on the RSP module using
the appropriate dust caps to prevent dust from accumulating inside the cage.
For information on dust caps, see
Installing Dust Caps.
Removing an RSP Module
Before you remove an RSP from the router, you should save the current
configuration on a TFTP server or an external USB flash drive, using the
copyrunning-config {ftp|
tftp|
bootflash:} command. This saves you time when
bringing the module back online.
If the module is running Cisco IOS software, save the current running
configuration by entering the
copyrunning-configstartup-config command.
Warning
Hazardous voltage or energy is present on the backplane when the
system is operating. Use caution when servicing. Statement 1034
Warning
Invisible laser radiation may be emitted from disconnected fibers
or connectors. Do not stare into beams or view directly with optical
instruments. Statement 1051
To remove an RSP module, perform the following steps:
Procedure
Step 1
Disconnect any cables attached to the ports on the module.
Step 2
Verify that the captive installation screws on all the modules in
the chassis are tight. This step ensures that the space created by the removed
module is maintained.
Note
If the captive installation screws are loose, the EMI gaskets
on the installed modules will push the modules toward the open slot, which in
turn reduces the size of the opening and makes it difficult to remove the
module.
Step 3
Loosen the two captive installation screws on the module you plan
to remove from the chassis.
Step 4
Place your thumbs on the ejector levers (see ) and simultaneously
rotate the ejector levers outward to unseat the module from the backplane
connector.
Step 5
Grasp the front edge of the module and slide the module straight
out of the slot. If the chassis has horizontal slots, place your hand under the
module to support its weight as you slide it out from the slot. Do not touch
the module circuitry.
Caution
To prevent ESD damage, handle modules by the carrier edges
only.
Step 6
Place the module on an antistatic mat or antistatic foam, or
immediately reinstall the module in another slot.
Step 7
Install blank module filler plates (Cisco part number
A90X-RSPA-BLANK-W) in empty slots, if any.
Warning
Blank faceplates and cover panels serve three important
functions: they prevent exposure to hazardous voltages and currents inside the
chassis; they contain electromagnetic interference (EMI) that might disrupt
other equipment; and they direct the flow of cooling air through the chassis.
Do not operate the system unless all cards, faceplates, front covers, and rear
covers are in place. Statement 1029
Hot-Swapping an RSP Module
The Cisco ASR 907 Router provides a feature that allows you to remove
and replace a redundant RSP module without powering down the router. This
feature, called hot-swapping or OIR, allows you to remove and replace a
redundant module without disrupting router operation.
When two redundant modules are installed in the router, only one of the
modules is active. The other one runs in standby mode, ready to take over
processing if the active module fails.
When you remove or insert a redundant module while the router is
powered on and running, the router does the following:
Determines if there is
sufficient power for the module.
Scans the backplane for
configuration changes.
Initializes the newly inserted module. In addition, the system notes
any removed modules and places those modules in the administratively shutdown
state.
Places any previously configured interfaces on the module back to
the state they were in when they were removed. Any newly inserted interfaces
are put in the administratively shutdown state as if they were present (but
unconfigured) at boot time. If you insert the same type of module into a slot,
its ports are configured and brought online up to the port count of the
original module.
The router runs diagnostic tests on any new interfaces and the test
results indicate the following:
If the tests pass, the router is operating normally.
If the new module is faulty, the router resumes normal operation but
leaves the new interfaces disabled.
If the diagnostic tests fail, the router stops operating, which
usually indicates that the new module has a problem in the bus and should be
removed.
Use the following guidelines when performing an OIR on an IM:
Allow at least 2 minutes for the system to reinitialize before
inserting a new IM.
Avoid inserting a new IM during bootup until the active and standby
RSPs have reached an OK state.
When inserting multiple IMs into the chassis, wait until each IM
reaches an OK state before inserting the next IM.
Installing the
Interface Module Carrier
Note
It is
recommended that you always install the IM carrier (A9XX-2IMA-CARRIER) in the
lower slot before installing the carrier in the upper slot.
Procedure
Step 1
Before
inserting an IM carrier, make sure that the chassis is grounded.
Step 2
To insert the
IM carrier, carefully align the edges of the IM carrier between the upper and
lower edges of the router slot.
Step 3
Carefully slide
the IM carrier into the router slot until the IM carrier makes contact with the
backplane. See the figure below.
Figure 22. Installing the IM Carrier
Interface Module

module.
Figure 23. Inserting an Interface Module
Step 4
ITighten the
locking thumbscrews on both sides of the interface module. The recommended
maximum torque is 5.5 in.-lb (.62 N-m).
Step 5
Connect all the
cables to each interface module.
What to do next
Caution
Do not use
interface module and power supply ejector handles to lift the chassis; using
the handles to lift the chassis can deform or damage the handles.
Note
Close all unused
RJ-45, SFP, XFP, and QSFP ports on the interface module using the appropriate
dust caps to prevent dust from accumulating inside the cage. For information on
dust caps, see
Installing Dust Caps .
Removing an Interface Module
Procedure
Step 1
To remove an interface module, disconnect all the cables from
each interface module.
Step 2
Loosen the locking thumbscrews on both sides of the interface
module.
Step 3
Slide the interface module out of the router slot by pulling on
the handles. If you are removing a blank filler plate, pull the blank filler
plate completely out of the router slot using the captive screws.
Hot-Swapping an
Interface Module
The Cisco ASR 907
Router provides a feature that allows you to remove and replace an interface
module without powering down the router. This feature, called hot-swapping or
OIR, allows you to remove and replace a redundant module without disrupting
router operation.
Note
The Cisco ASR 907
Router does not support hot-swapping an interface module with another module of
a different type. For example, you cannot swap an SFP Gigabit Ethernet module
with a copper Gigabit Ethernet module without disrupting router operation.
Note
If the TDM interface
module is swapped with the Gigabit Ethernet module in the same slot or
vice-versa, the router must be reloaded.
Note
If you perform OIR
on an interface module and move the module to a different slot, the router does
not retain the module configuration; you must reconfigure the interface module.
Replacing a configured interface module with a different interface module in
the same slot is not supported on the router.
Note
Always refer to the interface module compatibility matrix tables in the Data Sheet before you swap any IM.
When you remove or
insert a redundant module while the router is powered on and running, the
router does the following:
Determines if there is sufficient power for the module.
Scans the backplane for configuration changes.
Initializes the newly inserted module. In addition, the system notes any removed modules and places those modules in the administratively
shutdown state.
Places any previously configured
interfaces on the module back to the state they were in when they were removed.
The router runs
diagnostic tests on any new interfaces and the test results indicate the
following:
If the tests pass, the router is operating normally.
If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.
If the diagnostic
tests fail, the router stops operating, which usually indicates that the new
module has a problem in the bus and should be removed.
Caution
To avoid erroneous
failure messages, note the current configuration of all interfaces before you
remove or replace an interface module, and allow at least 2 minutes for the
system to reinitialize after a module has been removed or replaced. This time
is recommended in order to allow for synchronization between components within
the interface module and for synchronization with the standby RSP.
Installing the Power Supply
The Cisco ASR 907 router provides the choice of two different power supplies:
Attention
The RSP3-400-W requires only two PSUs (either AC or DC). We recommended you to use only two PSUs with RSP3-400-W in any of
the two slots of ASR 907 router.
1200 W DC power: - 40.8VDC to -72VDC
The DC power supply uses 3 position terminal block-style connector with positive latching or securing and labeled connections
for 48V, GRD, 48V. The terminal block connector is of suitable size to carry the appropriate AWG wire size to handle the input
current of the power supply. No ON/OFF switch is provided.
AC power: 85VAC to 264VAC
The AC power supply has an IEC-320-C21-type power receptacle and a 20-A service connector. You can use standard right angle
power cords with the AC power supply. The power supply includes a power cord retainer. No ON/OFF switch is provided.
Caution
The power supply must be wired before plugging the power supply in the chassis. Ensure that the branch circuit breaker is
turned off. Only after installing the power supply in the chassis, should the branch circuit breaker be turned on. The branch
circuit breaker must be turned off before unplugging the power supply.
Each power supply provides a single primary input power connection. You
can install dual power supplies for redundancy.
Warning
Read the installation instructions before connecting the system to
the power source. Statement 10
Note
Products that have an AC power connection are required to have an
external surge protective device (SPD) provided as part of the building
installation to comply with the Telcordia GR-1089 NEBS standard for
electromagnetic compatibility and safety.
Caution
Do not use the interface module and power supply ejector handles to lift the chassis. Using the handles to lift the chassis
can deform or damage the handles.
Preventing Power Loss
Use the following guidelines to prevent power loss to the router.
To prevent loss of input power, ensure that the total maximum load on each circuit supplying the power supplies is within
the current ratings of the wiring and breakers.
In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types that use ferroresonant
technology. These UPS types can become unstable with systems like the Cisco ASR 907 Router, which can have substantial current
draw fluctuations due to bursty data traffic patterns.
Use the information in the DC Power Supply Specifications table to estimate the power requirements and heat dissipation of
a Cisco ASR 907 Router based on a given configuration of the router. Determining power requirements is useful for planning
the power distribution system needed to support the router.
Power Connection Guidelines
This section provides guidelines for connecting the Cisco ASR 907
Router power supplies to the site power source.
Warning
Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate
electrical inspection authority or an electrician if you are uncertain that
suitable grounding is available. Statement 213
Warning
The plug-socket combination must be accessible at all times because
it serves as the main disconnecting device. Statement 1019
Note
The above statement is applicable only to the AC power supplies.
Warning
This product requires short-circuit (overcurrent) protection, to be
provided as part of the building installation. Install only in accordance with
national and local wiring regulations. Statement 1045
Guidelines for DC-Powered Systems
Basic guidelines for DC-powered systems include the following:
Each chassis power supply
should have its own dedicated input power source. The source must comply with
the safety extra-low voltage (SELV) requirements in the UL 60950, CSA 60950, EN
60950, and IEC 60950 standards.
The circuit must be
protected by a dedicated two-pole circuit breaker. The circuit breaker should
be sized according to the power supply input rating and local or national code
requirements.
The circuit breaker is considered the disconnect device and should
be easily accessible.
The system ground is the power supply and chassis ground.
Do not connect the DC return wire to the system frame or to the
system grounding equipment.

data carrier detect (DCD) and data terminal ready (DTR) operations.
Connecting a Management Ethernet Cable
When using the Ethernet Management port in the default mode (speed-auto
and duplex-auto) the port operates in auto-MDI/MDI-X mode. The port
automatically provides the correct signal connectivity through the
Auto-MDI/MDI-X feature. The port automatically senses a crossover or
straight-through cable and adapts to it.
However, when the Ethernet Management port is configured to a fixed
speed (10 or 100 Mbps) through command-line interface (CLI) commands, the port
is forced to MDI mode.
When in a fixed-speed configuration and MDI mode:
Use a crossover cable to
connect to an MDI port
Use a straight-through
cable to connect to an MDI-X port
Warning
To comply with the Telcordia GR-1089 NEBS standard for
electromagnetic compatibility and safety, connect the Management Ethernet ports
only to intra-building or unexposed wiring or cable. The intrabuilding cable
must be shielded and the shield must be grounded at both ends. The
intra-building port(s) 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 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.
Installing and Removing SFP and XFP Modules
The Cisco ASR 907 Router supports a variety of SFP and XFP modules,
including optical and Ethernet modules. For information on how to install and
remove SFP and XFP modules, see the documentation for the SFP or XFP module at
For information about inspecting and cleaning fiber-optic connections,
see
http://www.cisco.com/en/US/partner/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml
Caution
We recommend that you wait 30 seconds between removal and insertion
of an SFP on an interface module. This time is recommended to allow the
transceiver software to initialize and synchronize with the standby RSP.
Changing an SFP more quickly could result in transceiver initialization issues
that disable the SFP.
Connecting a USB

Connecting Ethernet Cables
The Cisco ASR 907 Router interface modules support RJ45 or SFP
Ethernet ports. For instructions on how to connect cables to Ethernet SFP
ports, see Connecting Cables to SFP Modules .
The RJ45 port supports standard straight-through and crossover
Category 5 unshielded twisted-pair (UTP) cables. Cisco Systems does not supply
Category 5 UTP cables; these cables are available commercially.
Warning
To comply with the Telcordia GR-1089 NEBS standard for
electromagnetic compatibility and safety, connect the Gigabit Ethernet ports
only to intra-building or unexposed wiring or cable. The intrabuilding cable
must be shielded and the shield must be grounded at both ends. The
intra-building port(s) 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 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.
Note
When installing the cabling to the RSPs, we recommend that you
leave a service loop of extra cabling sufficient to allow for fan tray removal.
Follow these steps to connect the cable to a copper Gigabit Ethernet
port:
Procedure
Step 1
Confirm that the router is powered off.
Step 2
Connect one end of the cable to the Gigabit Ethernet port on the
router.
Step 3
Connect the other end to the BTS patch or demarcation panel at
your site.
Connecting Cables to SFP Modules
For information on connecting cables to Cisco optical and Ethernet SFP interfaces, see
The physical layer interface for the Cisco ASR 907 Router T1/E1 port is
a customer-installed high-density connector. The high-density connector has
thumbscrews which should be screwed into the interface when the cable is
installed.
Note
Patch panels are required in order to connect the high-density
interface connectors to individual T1/E1 lines.
Installing the Cable Connectors
T1/E1 Cable
Connectors
One end of the cable (see the figure above) has a 68-pin connector that plugs into the T1/E1 interface module and the other
end of the cable with a 68-pin connector is connected to a RJ48, AMP64 or a DIN patch panel. Use the thumbscrews on either
side of the connector to secure the cable to the interface.
Figure 31. T1/E1 Cable Connector

RJ45 Cable Pinouts
T1 lines from individual subscribers are attached to RJ45 connectors on the front of the 24-port patch panel. Each RJ45 port
accommodates an individual T1 subscriber line.
For the T1/E1 ports, see the
T1/E1 Port Pinout
.
RJ48 Cable
Pinouts
T1 lines from individual subscribers
are attached to RJ45 connectors on the front of the 24-port patch panel. Each
RJ45 port accommodates an individual T1 subscriber line.
For the T1/E1 ports, see the T1/E1 Port Pinouts (RJ-48) section.
Connecting Cables to the Patch Panel
If you are connecting two T1/E1 interfaces to each other, you must
cable both interfaces’ patch panels together using a T1 cross-over cable or a
T1 straight-through cable. Use shielded cables. The type of cable you use
(cross-over or straight-through) depends on how the T1/E1 interfaces are cabled
to their patch panels:
If both T1/E1 interfaces
are connected to their patch panels in the same manner (TX to Transmit and RX
to Receive, or TX to Receive and RX to Transmit), use a T1 cross-over cable to
connect the patch panels.
If both T1/E1 interfaces
are connected to their patch panels in a different configuration (TX to
Transmit and RX to Receive on one interface, and TX to Receive and RX to
Transmit on the other interface), use a T1 straight-through cable (standard
RJ45 patch cable) to connect the patch panels.
Warning
To comply with the Telcordia GR-1089 NEBS standard for
electromagnetic compatibility and safety, connect the T1/E1 ports only to
intra-building or unexposed wiring or cable. The intrabuilding cable must be
shielded and the shield must be grounded at both ends. The intra-building
port(s) 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 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.

Patch Panel Cabling for Redundancy
You can connect the patch panels with the interface modules for redundancy, using the Y-cables. The Y-cable stub lengths
are reduced, so that the cable does not exceed from the rack spacer. The Y-cables are numbered based on the different stub
length. Cable lengths differ for even numbered and odd numbered slots in the chassis.
Note
Do not try to interchange the cables as the length may vary based on odd and even slots.

Connecting the Fan Tray Alarm Port
The fan tray includes an alarm port that maps to 4 dry contact alarm
inputs.
The pins on the alarm port are passive signals and can be configured
as Normally Open (an alarm generated when current is interrupted) or Normally
Closed (an alarm is generated when a circuit is established) alarms. You can
configure each alarm input as critical, major, or minor. An alarm triggers
alarm LEDs and alarm messages. The relay contacts can be controlled through any
appropriate third-party relay controller. The open/close configuration is an
option controlled in IOS.
Warning
To comply with the Telcordia GR-1089 NEBS standard for
electromagnetic compatibility and safety, connect the alarm ports only to
intra-building or unexposed wiring or cable. The intrabuilding cable must be
shielded and the shield must be grounded at both ends. The intra-building
port(s) 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 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.
Only Pins 1, 2, 4, 6, and 8 are available for customer use. The
remaining pins are for Cisco manufacturing test, and should not be connected.
Use a shielded cable for connection to this port for EMC protection. To
understand the pinouts on the alarm port in Troubleshooting.
Procedure
Step 1
Attach an RJ45 cable to the alarm port.
Step 2
Attach the other end of the RJ45 cable to the relay controller.
What to do next
For information about how to map alarm inputs to critical, major, and
minor alarm conditions, see the Cisco ASR 907 Router Software Configuration
Guide .
