7750 SR-a Chassis Features
7750 SR-a Chassis Features
The 7750 SR-a family of routers has two chassis models: the 7750 SR-a4 and 7750 SR-a8.
Both chassis are designed for a 19-in. (482.6 mm wide by 300 mm deep) EIA-310 rack with universal spacing. The chassis can also be installed in an ETSI 600 mm wide by 300 mm deep rack using the adapter brackets that are included with the chassis.
Each 7750 SR-a4 and 7750 SR-a8 router chassis is shipped with a backplane, card cage, and factory-installed air filter. Mounting brackets for the chassis are integrated so that the chassis can be mounted in a standard EIA-310 rack.
The AC or DC PSU, CPM-a, IOM-a, MDA-a, and fan tray components are packaged and shipped separately. Impedance panels, which are ordered separately, are required to cover empty slots to ensure cooling, for EMI containment during operation, and to prevent dust accumulation.
The chassis can be installed horizontally or vertically in the rack.
• In a horizontal installation, card slots are oriented horizontally; the fan tray and air filter are oriented vertically, and the airflow is side to side.
• In a vertical installation, card slots are oriented vertically; the fan tray and air filter are oriented horizontally, and the airflow is front to back. A vertical installation requires the Vertical Rack Mount Kit (3HE09608AA), which is sold separately.
Refer to the Vertical Rack Mount Kit Installation Guide (3HE10249AAAA TQZZA
Edition 01) for information about how to mount the 7750 SR-a4 and 7750 SR-a8 routers vertically.
Access to all 7750 SR-a components is from the front of the chassis.

The CPM-a does not provide a switch fabric. The IOM-a forwards traffic from the ingress to the egress ports.
At least one CPM-a must be installed in the 7750 SR-a chassis. The system cannot boot without a CPM-a installed in the chassis. Two CPM-a cards are required for system redundancy. The redundant standby (secondary) CPM-a operates in standby mode and takes over system operation if the active (primary) CPM-a fails. The 7750 SR-a CPM-a is intended only for the 7750 SR-a chassis and is not interchangeable with other 7750 SR products.
The CPM-a is field-replaceable and hot-swappable. Refer to the 7750 SR OS Basic System
Configuration Guide for information about CPM-a redundancy.
Each CPM-a supports two, Type-II capable compact flash (CF) memory devices:
• external CF slot—CF slot accessible from the front of the CPM-a card. The slot can support CF cards up to 32 Gbytes, and can be used to store accounting records, logs, and TiMOS images.
• internal CF slot—CF slot accessible on the circuit board when the CPM-a is removed from the chassis. This slot is used for the CF card that contains the system OS. See
CPM-a Internal CF Drive on page 34 for more information.

PSU Redundancy
Up to four PSUs can be installed in the front of each chassis. The chassis can support a mix of AC and DC power supplies.
For the 7750 SR-a4, one PSU can support the full system power requirements if you are operating without power redundancy. For redundancy, at least two PSUs must be installed and powered at all times.
7750 SR-a4 and SR-a8 Installation Guide 39
7750 SR-a Chassis Components
Note: For most applications, one PSU can power a 7750 SR-a4 system. However,
Alcatel-Lucent recommends that you calculate the maximum power consumption of all components in the chassis and install a second PSU, as required.
For the 7750 SR-a8, two PSUs are required to support the full system power requirements if you are operating without power redundancy. Three PSUs must be installed and powered at all times for (N + 1) redundancy.
All unused PSU slots must be filled with impedance panels to maintain EMI containment and proper air flow within the chassis.
Cooling System
The cooling system is designed to keep the internal components within the acceptable temperature range. The cooling system for the 7750 SR-a4 and 7750 SR-a8 has the following components:
• one fan tray
• one air filter with a reusable metal carrier and a field replaceable filter
• chassis right-side air intake and left-side exhaust
Fan Trays
The 7750 SR-a system is cooled by variable-speed fans housed in a fan tray. Air is pulled through the system from a right-side filtered-intake vent, through the chassis and across the line components, then exits through the fan tray in the left of the chassis.
The fan speed is reduced at normal temperatures and gradually increases up to its maximum speed as the ambient temperature increases. The fan trays are energy efficient and comply with NEBS3 acoustic requirements.
Fan trays are chassis-specific and described in Table 8
.

The fans are controlled by the system software, and their speed is set according to the environmental temperature surrounding the router. Allow at least 3 in. (7.6 cm) of clearance on each side of the rack to ensure adequate air intake and exhaust.
The fan LED located on the front panel of the fan tray indicates the tray status: normal online
for more information.
There are no field replaceable parts in the fan tray. The entire fan tray must be replaced if a component, such as a single fan, fails. See
Removing and Replacing a Fan Tray on page 185
for more information.
Fan trays must always be installed and fully operational while the 7750 SR-a chassis is powered.
Air Filters
Air filters are chassis specific:
• The 7750 SR-a4 chassis requires the 7750 SR-a4 filter.
• The 7750 SR-a8 chassis requires the 7750 SR-a8 filter.
Each chassis has one air filter slot that is located on the right side of the front panel.
The air filter has two parts: a reusable metal carrier, and a field replaceable filter. The reusable carrier and one air filter are shipped installed in the chassis.

Safety Considerations
This section contains safety information about the following:
•
•
•
•
•
•
•
Placement
Danger:
• Verify that the rack is correctly bolted, braced, and grounded to a grounding electrode.
Warning:
• Install the 7750 SR-a chassis in a clean, dry, ventilated, and temperature-controlled room.
• Install the chassis in the equipment rack before installing the components.
7750 SR-a4 and SR-a8 Installation Guide 61
Safety Considerations
Grounding
Danger: AC powered units
• Chassis ground cables are not included. Use only power cords that have a grounding
(earthing) path. Main grounding (earthing) connection points are through the IEC60320 appliance inlets. Grounding (earthing) points on the sides of the equipment are for equipotential bonding only and are safety grounding (earthing) points for the equipment.
Lack of correct grounding (earthing) of the equipment may result in a safety hazard and excessive electromagnetic emissions.
The ground conductor must be #8 AWG minimum or the same AWG as the power conductors if they are larger.
• The router and equipment rack must be correctly grounded. If you ground the equipment by a method other than those provided in this manual, that method should be in compliance with all local wiring regulations and practices.
Warning:
• Electrostatic discharge (ESD) damage can occur if components are mishandled.
Always wear an ESD-preventive wrist or ankle strap in contact with bare skin. Always connect the ESD strap (with banana plug) to the ESD connection socket (grounding jack) on the front of the chassis. An ESD strap is included in the accessory box that is shipped with the chassis.
Danger: DC powered units
• The 7750 SR-a includes a terminal for chassis ground on the front of the chassis. For both AC- and DC-powered deployments, the ground terminal must be connected.
Ensure that all power is OFF from the DC circuit. Locate the circuit breaker on the panel board that serves the DC circuit. Switch the circuit breaker to the OFF position. For extra safety, you can tape the handle of the circuit breaker to the OFF position.
• When wiring the unit, the ground connection must always be made first and disconnected last.
• The correct wiring sequence is -V BAT/negative to -V BAT/negative and 0V
RTN/positive to 0V RTN/positive.
The router is suitable for installation as part of the Common Bonding Network (CBN) or an
Isolated Bonding Network (IBN).
The router is suitable for installation in Network Telecommunication Facilities or locations where the NEC applies.

Cabling
Site Preparation
For information about grounding the chassis and connecting the AC or DC supply, see
Chassis Ground Wiring on page 85
; Installing, Wiring, and Connecting an AC PSU on page
Installing, Wiring, and Connecting a –48 VDC PSU on page 98 .
Warning:
• To comply with the GR-1089-CORE, Issue 06, requirement R4-9 [31] standard for electromagnetic compatibility and safety, all intra-building ports are specified for use with shielded and grounded cables at both ends.
• Intrabuilding ports of the equipment or subassembly are suitable for connection to intrabuilding or unexposed wiring or cabling only. Intrabuilding ports of the equipment or subassembly must not be metallically connected to interfaces that connect to the
Outside Plant (OSP) or its wiring or to equipment in an Isolated Bonding Network (IBN) unless the wiring passes through an SPCW as defined in GR-295. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 06) 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. For equipment installed in an IBN, use Mesh-BN,
Mesh-IBN, or Chain-IBN. Equipment rearrangements shall maintain the existing bonding topology.
• Bare conductors must be coated with an appropriate antioxidant compound before crimp connections are made. All unplated connectors, braided strap, and bus bars must be brought to a bright finish, then coated with an antioxidant before they are connected.
• The 7750 SR-a is suitable for use in DC-I, DC-C, or AC powered installations. There are no connections between the battery returns and the chassis ground within the
7750 SR-a.
7750 SR-a4 and SR-a8 Installation Guide 63
Safety Considerations
Power
Danger:
• Only trained and qualified electrical service personnel should perform wiring and cabling to the system.
• All power to the equipment rack or cabinet should be disconnected before the installation.
• The power cables must be copper and meet your local electric code requirements.
• The circuit breaker is not intended to be used as the chassis ON/OFF switch.
Disconnect the power from the power source to remove power.
• The 7750 SR-a routers with DC PSU modules should be installed only in restricted access areas (such as dedicated equipment rooms and electrical closets).
• An external circuit breaker no greater than 60 A must be located within a readily accessible distance of the equipment. This is intended as the disconnect device.
DC Power Requirements
• A disconnect device must be provided within 9.84 ft (3 m) of the 7750 SR-a chassis.
• A #8 AWG (maximum) power conductor must be provided for each of the DC input connections.
AC Power Cord Requirements by Country
The following AC power cord requirements are applicable to all countries:
• The length of the power cord must be at least 6 ft (1.8 m) and a maximum of
9.75 ft (3.0 m).
• All power cords must be approved by an acceptable accredited agency responsible for evaluation in the country where the power cord set is used.
• The power cord must have a minimum current capacity of 10 A and a nominal voltage rating of 220 or 240 VAC, as required by each country’s power system. The power cord must have a minimum current capacity of 12 A for 100V-120 VAC.
• The appliance coupler must meet the mechanical configuration of an EN 60 320/IEC
320 Standard Sheet C13 connector for mating with appliance inlet on the unit.

Installing the 7750 SR-a Chassis
Chassis Ground Wiring
Danger:
• Only trained and qualified personnel should install or replace this equipment.
• The 7750 SR-a chassis ground studs located on the left-hand side mounting bracket must be a permanent connection to the earth (building) ground point. The connection requires the use of the supplied lug and nuts.
• When wiring the 7750 SR-a router, the ground connection must always be made first and disconnected last.
Preparing the Ground Wire
The 7750 SR-a chassis must be correctly connected to earth ground.
Grounding cables are not provided with the 7750 SR-a chassis. The length of the grounding wire that you need depends on the location of the 7750 SR-a router and its proximity to the correct grounding facilities. You must use a minimum of #8 AWG wire for the ground connection.
Alcatel-Lucent supplies the chassis ground lug (Burndy YAZ8C2TC1045, Alcatel-Lucent
PN 52-1178-01). Because of the compact design of the 7750 SR-a chassis, the lug is angled at 45 degrees. The lug and two 10-32 nuts are included in the accessory kit that is shipped with the chassis. The lug is designed for #8 AWG ground wire.
Note: If you require a gauge larger than #8 AWG, the lug must be a two-hole, 45-degree lug for #10 studs. The spacing between the two holes in the lug must be 5/8 in. (1.59 cm).

Installing the Wire-Form Cable Guides
Note: When routing cables to the sides of the chassis, the egress cables may impede the removal and replacement of the fan on the left or the air filter on the right. For this reason, left mounting the cable guide may be the preferred option, because the air filter must be removed frequently for inspection.
Guides are normally installed after the chassis is mounted in a rack. For EIA racks, you must remove two of the four rack-mount screws completely, then re-use the screws to mount the guides to the chassis and the chassis to the rack. If ETSI brackets are used, you can install the guides with the adapter brackets before you mount the chassis in the rack.
Required tools:
• a torque driver for the cable guide screws. Refer to the rack manufacturer’s documentation for instructions.
• EIA rack screws (not supplied), or 12-24 screws supplied with the ETSI adapter brackets
To install the wire-form cable guides:
Step 1.
Remove the screws in holes 1 and 3 on the left side of the chassis flange.
Step 2.
Orient the cable guide so the mounting eyelets are pointing toward the chassis, as indicated in
.
Step 3.
Replace and tighten the two screws. Refer to the rack manufacturer’s documentation for instructions. See
Torque Specifications for Rack Mounting on page 59
for more information.
Step 4.
Remove the screws in holes 2 and 4 on the right side of the chassis flange.
Step 5.
Orient the cable guide so the mounting eyelets are pointing toward the chassis, as indicated in
.
Step 6.
Replace and tighten the two screws. Refer to the rack manufacturer’s documentation for instructions. See
Torque Specifications for Rack Mounting on page 59
for more information.

Warnings and Notes
Danger:
• Only trained and qualified personnel should install or replace this equipment and connect the power cables.
• Confirm that the DC power source is OFF during installation. The power source should be a safety extra-low voltage (SELV) source.
• Turn off power at the power source before you install or remove power cords.
• Before working on equipment that is connected to power, remove jewelry, such as rings, necklaces, and watches. When metal objects are in contact with power and ground, serious burns can occur or the objects can be welded to the terminals.
• Make all ground connections first.
• The router and equipment rack must be correctly grounded.
• You must use power cables that meet the local electrical code requirements.
• This product relies on the building’s installation for short-circuit (overcurrent) protection.
For AC powered systems, ensure that a circuit breaker, or other equivalent means, rated 20 A, is used in the building’s AC branch circuit for the current carrying conductors.
• For DC powered systems, the unit should be connected to a DC branch circuit with a maximum 60 A circuit breaker that meets the requirements for branch circuit protection.
A suitable disconnect device must be provided in the DC branch, either a circuit breaker or switch that can disconnect power from the system during servicing.
Warning:
• Impedance panels are required in all empty slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference. Impedance panels do not have board components or connector pins.
• Electrostatic discharge (ESD) damage can occur if components are mishandled.
Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis.
• Do not install equipment that appears to be damaged.
92 7750 SR-a4 and SR-a8 Installation Guide
Installing PSUs
Note:
• The 7750 SR-a4 chassis requires a minimum of one PSU to operate, but two are recommended for redundancy. The 7750 SR-a8 chassis requires a minimum of two
PSUs to operate, but four are recommended for redundancy.
• For full redundancy, each PSU module should be attached to an independent power source with a dedicated circuit breaker. A fully redundant system must be connected to both DC PSU modules, or both AC PSU modules, or one DC and one AC PSU module.
• In the event of a PSU module failure, the entire AC or DC PSU must be replaced. There are no field-serviceable parts inside the PSU.
• Empty PSU slots in the chassis must be covered by impedance panels. Panels must be ordered separately. See
Impedance Panels on page 43 for more information.

Installing, Wiring, and Connecting an AC PSU
AC-Input Power Supply Guidelines
Danger:
• The AC power cord is not supplied and must be ordered to comply with local country codes and the intended voltage. When applying power to the chassis, be sure to use an approved AC power cord set, and ensure that you do not use any other product's AC power cord set.
• AC units are rated 100-120 V or 200-240 V. For 100-120 V, you must use a cord rated for a minimum of 12 A. For 200-240 V, you must use a cord rated for a minimum of 10 A.
• For AC powered units, use only power cords that have a grounding (earthing) path.
Main grounding (earthing) connection points are through the IEC60320 appliance inlets.
Grounding (earthing) points on the front of the equipment are for equipotential bonding only and are not the safety grounding (earthing) points for the equipment. Lack of correct grounding (earthing) of the equipment may result in a safety hazard and excessive electromagnetic emissions.
Warning:
• If you ground the equipment by a method other than those provided in this manual, that method should be in compliance with all local wiring regulations and practices.
• In order to comply with the GR-1089 Lightning Criteria for Equipment Interfacing With
AC Power Ports, an external Surge Protective Device is intended to be used at the AC input of the router.
Note: To facilitate power redundancy, you must connect all PSU modules to an appropriate
source (see DC-Input Power Supply Guidelines on page 100 .)
Connecting the AC Power Cord to the PSU
There is one input AC power cord receptacle for each AC PSU. The AC PSU has an AC plug inlet to accept an AC power cord. The other end of the AC power cord must have a plug that
can fit into the power source receptacle that is standard for your geographic region. Figure 28
shows how to connect the AC power cord.
Table 41 describes the connections.
96 7750 SR-a4 and SR-a8 Installation Guide
Installing PSUs
Warning: Do not apply power to the chassis. The chassis does not have an ON/OFF switch.
The unit will be powered on if you plug the power cord into an AC power source receptacle.

Installing, Wiring, and Connecting a –48 VDC PSU
DC-Input Power Supply Guidelines
Danger:
• Ensure that all power is OFF from the DC circuit. Locate the circuit breaker on the panel board that serves the DC circuit. Set the circuit breaker to the OFF (O) position.
• When wiring the unit, the ground connection must always be made first and disconnected last.
• The correct wiring sequence is positive PSU terminal to the power source return terminal, and negative PSU terminal to the –48V terminal.
• 7750 SR-a systems equipped with DC-input power supplies should be installed in restricted access areas, such as a dedicated equipment room or an equipment closet, in accordance with Articles 110-16, 110-17, and 110-18 of the National Electric Code
ANSI/ NFPA 70.
Warning:
• Use a minimum of #8 AWG wire for the –48 VDC and RTN connections.
• Use a minimum of #8 AWG wire for the ground connections.
• A ring lug (approved by an accredited safety agency) and associated approved crimp tool must be used.
• Consult your local electrical code for more information.
If you intend to use DC-input power in the 7750 SR-a chassis, observe the following:
• The 7750 SR-a4 chassis requires a minimum of one PSU to operate, but two are recommended for redundancy. The 7750 SR-a8 chassis requires a minimum of two
PSUs to operate, but four are recommended for redundancy.
• A fully redundant system operates with two power systems. AC and DC power types are available in the 7750 SR-a chassis. Ideally, the power sources should be connected to separate breakers.
• DC-input power connections require copper wire cables.
• DC power cables are not shipped with the 7750 SR-a chassis.
• For DC power connections, a ground connection on the chassis is required.
Grounding cables are not provided.
Wiring the DC Inputs
The –48 VDC PSU has one ground screw and a terminal block with positive and negative

7750 SR-a4 and SR-a8 Installation Guide 119
Managing Cable Connections to MDA-a and MDA-aXP Cards
Managing Cable Connections to MDA-a and MDAaXP Cards
All cable connections to MDA-a cards are made from the front of the 7750 SR-a chassis. The
MDA-a cards can be connected using Ethernet, copper, or fiber-optic cables. The 7750 SR-a chassis are designed to enable cable routing and management from the front of the chassis.
Ethernet and Copper Wire Cables
For a horizontally mounted chassis, Ethernet and copper wire cables can be routed to the left or right of the chassis using the (optional) wire-form cable management brackets, described
in Installing the Wire-Form Cable Guides on page 89
.
To maintain EMC compliance, cables that are shielded and grounded at both ends must be used with the adapter card interfaces. Use CAT5e shielded cables with Gigabit Ethernet interfaces (electrical).
Warning: To prevent damage to the components during installation, such as damage to the faceplate connectors, avoid excessive bending, twisting, and pulling of Ethernet and copper wire cables. When bundling the cables, leave enough slack to allow room to move the cables aside during servicing and to prevent stress at the termination to the module.
To attach Ethernet and copper wire cables:
Step 1.
Attach the cable to the port connector or SFP connector on the adapter card.
Step 2.
Route the cables to the left or right of the chassis.
Step 3.
Attach the cable to a distribution panel or appropriate connector.
120 7750 SR-a4 and SR-a8 Installation Guide
Installing Components
Fiber Cables
Warning:
• Fiber cables are sensitive to bending, twisting and pulling. Extreme caution is recommended when handling fiber cable.
• To ensure that the minimum fiber bend radius is maintained in the allowable space
AT&T TP-76450 specifies a minimum of 1.0 in (25.4 mm) inside radius for single fibers.
• Use fiber cable with a pre-installed open-angled 90º boot.
• Observe correct fiber connector handling regarding the use of dust covers and cleaning.
Fiber-optic cables are routed in a similar fashion to Ethernet and copper wire cables. Cables are routed to the left or right of the chassis.
Hardware required:
• Velcro straps (optional)
To attach fiber cables:
Step 1.
Attach the cable to the port connector or SFP connector on the adapter card.
Step 2.
Route the cables to the left or right of the chassis. If needed, use a Velcro strap to bundle the cables from each card.
Step 3.
Attach the fiber cable to a distribution panel or appropriate connector.
Alarm Port Connections
The Alarm port on the CPM-a has a 15-pin DB connector. Use a shielded cable to connect the Alarm port to a suitable alarm panel, such as a punch-down or wire-wrap panel. See
Alarms Interface Port Pinouts on page 218 for the required pinout information.
To connect the Alarm port:
Step 1.
Connect the cable assembly to the External Alarm port.
Step 2.
Route the cable to the left or the right of the chassis.
Step 3.
Connect the far end of the cable to the alarm panel.

Powering Up the 7750 SR-a
Powering Up the 7750 SR-a
The 7750 SR-a4 and 7750 SR-a8 do not have a power switch or internal circuit breaker to turn the power ON or OFF:
• For AC power, power is supplied from an AC power outlet.
• For –48 VDC power, the 7750 SR-a system DC power is supplied by a DC branch circuit.
Danger:
• You must comply with the general safety precautions and product requirements described in
Site Preparation on page 47 and the requirements described in
PSUs on page 91 before performing the procedures contained in this chapter.
• Do not power up a 7750 SR-a before verifying that all common equipment (chassis, power, cooling, and grounding) is connected correctly.
• Always keep your fingers away from rotating fan blades. Do not put your fingers or any tool in the fan tray if the fans are still spinning.
Warning: For correct thermal operation, ensure that Impedance panels are installed in all empty slots before powering up the 7750 SR-a.
Note:
• You must complete the procedure

• The primary copy of the 7750 SR-a TiMOS software is located on the compact flash
memory card that must be installed on the CPM, as described in Installing the Internal
CF Card on the CPM-a on page 111
.
• At power up, the fans initially run at full speed. Thereafter, the control system reduces the fan speed based on temperature. During normal operation, fans never turn off completely.
Power-Up
To power-up an AC powered system:
126 7750 SR-a4 and SR-a8 Installation Guide
Powering Up, Initializing, and Configuring
Step 1.
To initiate the boot process, plug the male end of the power cord into a 3-terminal, single-phase power source that provides power within the acceptable range, as described in
Step 2.
Check that the LED on each PSU is green. A green LED indicates that the AC standby and main power supply outputs are operating within specification. If the
LED is off, there is no power input. Refer to
for more information.
To power-up a DC powered system:
Step 1.
Turn on the power at the remote power sources to initiate the boot process.
Step 2.
Check that the LED on each PSU is green. A green LED indicates that the DC standby and main power supply outputs are operating within specification. If the
LED is off, there is no power input. Refer to
for more information.
Component LED Verification
To verify that the components power up correctly:
Step 1.
Verify that the system is initializing.
The system searches the CF card on the CPM for the boot.ldr
file (also known as the bootstrap or boot loader file).
The Status LED on the CPM-a slowly blinks green during initialization.
After initialization (approximately 30 s), the Status LED on the active CPM turns solid green to indicate that the CPM boot/load process is complete and that the
CPM-a is operational as the primary CPM.
The Status LED on the inactive secondary CPM-a rapidly blinks green to indicate that the CPM-a boot/load process is complete and that the CPM-a is operational as the secondary CPM-a.
If the LEDs do not operate as described above, or if they blink and turn off, refer to
Troubleshooting Initial Startup on page 134
.
Step 2.
Verify the operational status of the router components by checking all the LEDs on the CPM-a, IOM-a, fan tray and MDA-a components.
Refer to
Appendix A: Connectors and LEDs on page 137 and
Appendix B: MDAa and MDA-aXP Card Descriptions on page 147

Telnet Connection
After a successful initialization, you can access the router with a Telnet connection from a PC
or workstation connected to the network, after the management port (see Figure 43
) has been configured using the bof>address
command. Telnet access provides the same options for user and administrator access as those available through the Console port.
To configure the 7750 SR-a for Telnet access, you need to have a device with Telnet software located on the same network. The 7750 SR-a must have a management IP address. The IP address is manually configured. Each 7750 SR router is limited to a total of seven inbound/ outbound Telnet or SSH sessions to guarantee that either inbound or outbound sessions will be available. For information about configuring router parameters, refer to the appropriate
Router Configuration Guide. For pinout information, refer to Appendix D: CPM-a Pinout

Troubleshooting Initial Startup
Troubleshooting Initial Startup
If the Status LED does not light after 30 s, as described in
Component LED Verification on page 127
, the compact flash card is most likely faulty.
If the system cannot load or cannot find the boot.ldr
file on the cf3: slot, the Status LED on the CPM turns off and the system checks for a manual boot sequence interruption. Perform a manual boot sequence interruption by connecting a terminal to a Console port and pressing any key when prompted by the display. Unless an unsuccessful system initialization is manually interrupted, the system will continuously reboot in an attempt to successfully find and load the boot.ldr
file. Insert a compact flash card with the appropriate boot.ldr
file into the cf3: slot, as described in
Replacing the Internal Compact Flash Card on the CPMa on page 195
.
When the system finds the boot.ldr
file, the system processes the initialization parameters from the BOF. The BOF must be on the same drive as the boot loader file. If the BOF cannot be found or loaded, the system prompts for a different image and configuration location.
When the image is successfully loaded, control is passed from the boot loader file to the image. The runtime image attempts to locate the configuration file as configured in the BOF.
The configuration file include chassis, IOM-a, MDA-a, and port configurations, as well as system, routing, and service configurations.
The following example shows the output when either no flash is present or the boot.ldr file cannot be found.

Rebooting...
When the system finds the boot.ldr
file, the system processes the initialization parameters from the BOF (boot option file). The BOF should be on the same drive as the boot.ldr
file. If the BOF cannot be found or loaded, then the system prompts the user for alternate software and configuration file locations.
When the system software is successfully loaded, control is passed from the boot loader file to the system software. The system software attempts to locate the configuration file as configured in the BOF. The configuration file includes chassis, CPM-a, IOM-a, MDA-a, and port configurations, as well as system, routing, and service configurations.
It is important that cables connected to the Console port on the 7750 SR-a chassis are correctly terminated and terminal servers should be correctly configured so as to not negatively affect the functioning of the node.
Noisy lines can be interpreted by the node as keystrokes and could interrupt the boot sequence resulting in an outage. After reboot, the CPM can go into a continuous reboot cycle if the boot process is interrupted by random characters received on the Console port.
To prevent random characters received on the Console port, terminate all console connections. If a terminal server is connected to the 7750 SR-a CPM-a ensure that it is configured to not send unwanted characters to the CPM-a that could interrupt the boot cycle.
For example, configure a no exec
or equivalent CLI command on the terminal server.

Port Line Rate
The 2-port 10GigE SFP+ and 12-port 1GigE SFP Combo MDA-a car is an oversubscribed 25
Gb/s MDA-a. The card’s connection to the IOM is only 25 Gb/s.
If you install both 10GE ports and more that five 1GE ports, the card will be oversubscribed.
If all twelve 1 GE ports and one 10GE port are installed, only 22 Gb/s are used. In this scenario, the other 10GE port could be used as a standby link, and the card would not be oversubscribed.
The card is limited to 25 Gb/s, installing the card in a 100 Gb/s slot does not increase the throughput.

Port Line Rate
The 4-port 10GigE SFP+ MDA-a card is an oversubscribed 25 Gb/s MDA-a. The card’s connection to the IOM is only 25 Gb/s. The card supports 10 Gb/s line rate out of each port only if 2 or fewer ports are in use.
If more than 2 ports are in use, the per-port maximum simultaneous line rate diminishes as a ratio of 25 Gb/s divided by the number of ports in use. For example, if all 4 ports are installed and are run at full speed, the line rate is approximately 25 Gb/s divided by 4 ports, which is
6.25 Gb/s per port.

Port Allocation
The type of modules that you install affects the numbering of the allocated ports.
One dual-port-CSFP occupies one slot and two ports. If all 22 slots have dual-port CSFPs installed, 44-ports are allocated. The card requires 22 CSFPs for full 44-port operation.
One single-port SFP occupies one slot and one port. Single-port SFPs use one odd-numbered port when plugged into a CSPF slot. If all 22 slots have single-port SFPs installed, 22 ports are allocated as 1, 3, 5...41, 43.
The card also supports a mixed configuration of CFSPs and SFPs. If you install a mix of single-port and dual-port (CSFP) modules, the allocated port numbers will be non-consecutive. For example, if the first and fourth modules are dual-port CSPFs and the second and third modules are SFPs, the following ports are used 1, 2, 3, 5, 7, 8.
Port Line Rate
The 1GigE CSFP/SFP MDA-a card is an oversubscribed 25 Gb/s MDA-a. The card’s connection to the IOM is only 25 Gb/s. The card supports 1 Gb/s line rate out of each port only if 25 or fewer ports are in use.
7750 SR-a4 and SR-a8 Installation Guide 167
44-port 1GigE CSFP/SFP MDA-a Overview
If more than 25 ports are in use, the per-port maximum simultaneous line rates diminishes as a ratio of 25 Gb/s divided by the number of ports in use. For example, if all 44 ports are installed and are run at full speed, the line rate is approximately 25 Gb/s divided by 44 ports, which is 560 Mb/s per port.
The card is limited to 25 Gb/s; installing the card in a 100 Gb/s slot does not increase the throughput.

Warnings and Notes
Danger:
• Make the ground connections first.
• Only trained and qualified personnel should install or replace this equipment and connect the power cables.
• External power must be disconnected at the power source. Disconnect and unplug the power cables before you remove and replace a PSU module.
• You must use power cables that meet local electrical code requirements.
Warning:
• Do not install equipment that appears to be damaged.
• Impedance panels are required in all empty slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference. Impedance panels do not have board components or connector pins.
• Electrostatic discharge (ESD) damage can occur if components are mishandled.
Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis.
172 7750 SR-a4 and SR-a8 Installation Guide
Appendix C: Field-Replaceable Units
Note:
• The 7750 SR-a4 chassis requires a minimum of one PSU to operate, but two are recommended for redundancy. The 7750 SR-a8 chassis requires a minimum of two
PSUs to operate, but four are recommended for redundancy.
• For full redundancy, each PSU module should be attached to an independent power source with a dedicated circuit breaker. A fully redundant system must be connected to both DC PSU modules, or both AC PSU modules, or one DC and one AC PSU module.
• In the event of a PSU module failure, the entire module must be replaced. There are no field-serviceable parts inside the PSUs.
7750 SR-a AC PSU
If you are operating your 7750 SR-a with redundant PSU modules, you can install, remove, or replace a PSU module without affecting system operation.
Danger: Unplug the power cable from the remote power source during the PSU module removal and replacement procedures.
Note: Refer to
7750 SR-a –48 VDC PSU LED and Connectors on page 139
for a description of the PSU.

7750 SR-a –48 VDC PSU
If you are operating the 7750 SR-a with redundant PSU modules, you can install, remove, or replace a PSU module without affecting system operation.
7750 SR-a4 and SR-a8 Installation Guide 177
Removing and Replacing a PSU
Danger:
• Ensure that all power from the DC circuit is OFF. Locate the circuit breaker on the panel board that serves the DC circuit. Switch the circuit breaker to the OFF position. For extra safety, lock out the circuit breaker by taping the handle of the circuit breaker in the OFF position.
• When wiring the unit, the ground connection must always be made first and disconnected last.
• The correct wiring sequence is ground/negative to ground/negative and positive/return to positive/return.
Note:
Refer to 7750 SR-a –48 VDC PSU LED and Connectors on page 139
for a description of the PSU.

Removing and Replacing a Fan Tray
The procedures in this section apply to the following fan trays:
• SR-a4 fan tray for the 7750 SR-a4 5-RU chassis
• SR-a8 fan tray for the 7750 SR-a8 7-RU chassis
Where figures in this section only show the fan tray that is used in the 7750 SR-a4 chassis, the figures also apply to the 7750 SR-a8 chassis.
This section includes information about:
•
Warnings and Notes on page 185
•

•
Replacing a Fan Tray on page 187
Warnings and Notes
Danger: Always keep your fingers away from rotating fan blades. Do not put your fingers or any tool in the fan tray if the fans are still spinning. Wait until the fans stop spinning (about
2 s) before completely removing the fan tray from its slot.
Warning:
• The fan tray is hot-swappable. The 7750 SR-a chassis operates safely for up to one minute while you replace the fan tray. If a longer maintenance time is required, power off the system to prevent over-heating.
• In the event of a single fan failure, the remaining fans switch to their highest speeds.
The remaining fans continue to provide adequate cooling for the system, but the fan tray must be replaced as soon as possible. Individual fans are not field replaceable.
Note: When a fan tray is replaced, the fans initially run at full speed. Thereafter, the control system reduces the fan speed based on temperature. During normal operation, fans never turn off completely.

Appendix C: Field-Replaceable Units
Removing and Replacing an Impedance Panel
Empty slots in the chassis must be covered by impedance panels. Panels must be ordered
separately. See Impedance Panels on page 43
for more information.
If you need to install a component in a slot which has an impedance panel, remove the panel only when you are ready to install a component in its place.
An impedance panel slides into a slot using the chassis slot guides in the same way as the corresponding component. MDA and IOM impedance panels have captive screws to secure the panel. PSU impedance panels have a latch lock that operates like the latch lock on the PSU components.

Management Port
Use a shielded twisted-pair (STP) cable for RJ-45 connections and 100-ohm Category 3, 4, or 5 cable for 10 Mb/s connections or 100-ohm Category 5 cable for 100 Mb/s connections.
Make sure that the length of any shielded twisted-pair cable does not exceed 328 ft (100 m).
The RJ-45 ports on the router support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port on these switches, you can use either straight-through or crossover cable.

Alarms Interface Port
The alarms interface port is a D-type 15-pin 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 causes 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.
shows the DB-15 Alarm Connector. Pinouts are numbered as follows:
• top row: right to left, pins 1 to 8
• bottom row: right to left, pins 9 to 15
Figure 81: DB-15 Receptacle Alarm Connector

24597
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 24 VDC to 48
VDC. 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 activate the appropriate alarm output pin.

RTN refers to the negative side of the Alarm-In connections when a floating power supply is used. If an external power supply is used as the voltage source for Alarm-In 1-4, 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 DB15 connector, the
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 +24 VDC supply providing that the plug mounting (hold down) screws are firmly attached to the 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 chassis and can be manually cleared by pressing the ACO button.
The four alarm inputs are customer configurable to monitor alarms provided by additional
equipment. See Figure 82 . These inputs must use one of the following:
• the voltage source provided on pin 4 of the DB15 connector
• a separate isolated DC power supply, rated between 18 to 50 VDC at 100 mA
If an external power source is used, its outputs must be isolated from chassis ground, as shown in
. Do not connect the alarm power supply return to the chassis or rack ground in this scenario.

Warnings and Notes
Warnings and Notes
Danger:
• Fiber-optic equipment can emit laser or infrared light that can injure your eyes. Never look into an optical fiber or connector port. Always assume that fiber-optic cables are connected to a light source.
• CFP and QSFP+ pluggable optic modules are very hot while in use. Touch only the captive screws when removing the module. Allow the module to cool before further handling.
Warning:
• Make sure that the safety cap on the transceiver is inserted while you install or remove the SFP, SFP+, CSFP, CFP, or QSFP+ transceivers. Only remove the safety cap when you are ready to attach network cables.
• Always replace the dust cover when the SFP, SFP+, CSFP, CFP, or QSFP is removed.
• Use only approved small form factor pluggable (SFP) and compact form factor pluggable (CFP) fiber-optic devices in MDA-a ports.
• Before using the optics, verify that the optical path is in compliance with the parameters of the optical components. In particular, verify any minimum attenuation requirements for the optics. If minimum attenuation requirements are not met, the optical receiver components may be permanently damaged.
• Electrostatic discharge (ESD) damage can occur if router components, including SFP,
SFP+, CSFP, CFP, and QSFP+ transceivers are mishandled. Always wear an ESDpreventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis.
Caution:
• Always place router components on an antistatic surface.
• Avoid bending fiber-optic cable beyond its minimum bend radius.
• Do not exceed the recommended minimum bend radius for fiber-optic cables. AT&T TP-
76450 specifies 1.0 in. (25.4 mm) inside radius for single fibers.
Note:
• Discard SFP, SFP+, CSFP, CFP, and QSFP+ transceivers according to all local laws and regulations.
• SFP, SFP+, CSFP, CFP, and QSFP+ transceivers can be installed and replaced without disabling the interfaces.
• SFP, SFP+, CSFP, CFP, and QSFP+ transceivers are keyed to prevent incorrect insertion.
222 7750 SR-a4 and SR-a8 Installation Guide
Appendix E: Pluggable Transceivers
Preparation
Clean the connector on the fiber cable before inserting it into the transceiver to prevent the transfer of small particles and contaminants to the transceiver. If you switch an SFP, SFP+,
CSFP, CFP, or QSFP+ from one port to another ensure that you clean the fiber connectors before reinserting them.
Apply high standards when inspecting and cleaning fiber connectors. Use a “dry” cleaning method to clean fiber connectors.To clean the connector, you can either:
• Wipe the side and end of the ferrule with a lint-free alcohol-dampened cloth.
• Blow dry the ferrule with compressed air and inspect for lint. Do not insert the compressed air nozzle into the receptacle.
Locking Mechanisms
SFP, SFP+, CSFP, CFP, and QSFP+ transceivers use different lock and release methods.
Possible lock and release mechanisms include:
• Bail— A bar or wire in the front of the transceiver that you use to release the module.
SFP, SFP+, and CSFP transceivers use bail-actuated bottom latching. QSFP+ use bail-actuated side latching.
• Captive screws—Fixed screws on both sides of the transceivers. Screws are used on
CFP transceivers.

A CFP module can be installed on the following MDA-aXP card:
• 1-port 100GigE CFP MDA-aXP
Installing an SFP, SFP+, CSFP, or QSFP+
To install an SFP, SFP+, CSFP, or QSFP+ transceiver:
Step 1.
Locate the transceiver receptacle on the MDA-a card.
Step 2.
Remove the transceiver from its antistatic packaging.
Step 3.
While holding the transceiver by its sides, slide the unit into the port at the correct angle. If other transceivers are present, you may need to push on the face to fully seat the transceiver. The transceiver is seated when it clicks into place. See
Figure 84 . Table 112 describes the SFP installation features. The same features
apply to SFP+s and CSFPs.
