Installing the Supervisor in the Cisco cBR
Chassis
This section provides information on installing the Supervisor.
Check if your hardware might have a supervisor card. For supervisor cards that are shipped as a spare module,
the supervisor card bootflash would be empty. Ensure that you manually copy the image on the bootflash to
avoid issues while booting.

Installing the Supervisor 250G
Installing the Supervisor PIC in the Cisco cBR Chassis
Perform this procedure to install the following PICs:
•Supervisor PIC
•Blank PIC for the Supervisor
Do not support mix use of 250G and 160G SUP and SUP-PIC.Note
Before You Begin
If you are adding a new Supervisor PIC or upgrading the existing Supervisor PICs, ensure that the power
modules installed in the chassis are adequate to support the Supervisor PICs.
Warning
•Attach an ESD-preventive wrist strap to your wrist and connect the other end to the grounding lug
connected to the chassis.

•Be aware of the weight and size of the equipment. Handle it with care.
Restrictions
•If you are using a single Supervisor, you must install the Supervisor PIC in the slot corresponding to
the Supervisor Card.
In the Cisco cBR-8 router,Note
•Slot 4/1 for the Supervisor PIC corresponds to slot SUP0 for the Supervisor Card.
•Slot 5/1 for the Supervisor PIC corresponds to slot SUP1 for the Supervisor Card.
Required Tools and Equipment
•ESD-preventive wrist strap
•Supervisor PIC or blank PIC for the Supervisor
•3/16" flat-blade torque screwdriver
Step 1 Grasp the faceplate of the PIC with one hand and place your other hand under the PIC to support its weight.
Step 2 Carefully align the PIC with the plastic guides in the slot.
Step 3 Slide the PIC into the slot applying even pressure using both your hands until it is within an inch of full insertion.
Step 4 Open the ejector levers and fully insert the PIC into the slot applying even pressure on both sides until it mates with the
midplane connectors.

Step 6 Tighten the four captive screws using a 3/16" flat-blade torque screwdriver with a torque of 6-8 in-lb (0.68-0.90 Nm) to
secure the PIC.
What to Do Next
•If you are using a single Supervisor PIC, install a blank PIC for the Supervisor in the empty slot.
•Install the Supervisor PIC cable management bracket (recommended).
•Install the Supervisor Card (if not already installed).
Installing the Supervisor PIC Cable Management Bracket
The Supervisor PIC cable management bracket is shipped separately in the chassis accessory kit. It has a
smaller slot for fiber-optic cables and a larger slot for the RJ-45 cables.
Before You Begin
•Attach an ESD-preventive wrist strap to your wrist and connect the other end to the grounding lug
connected to the chassis.
•Install the Supervisor PIC (recommended).

Step 1 Align the captive screws on the Supervisor PIC cable management bracket with the mounting holes on the Supervisor
PIC.
Ensure that the lower slot in the cable management bracket is the smaller slot for fiber-optic cables and the
upper slot is the larger slot for RJ-45 cables.

Step 2 Tighten the captive screws using a 3/16" flat-blade torque screwdriver with a torque of 6-8 in-lb (0.68-0.90 Nm) to secure
the Supervisor PIC cable management bracket.
What to Do Next
•Install the chassis-mounted fiber/cable routing guide (if not already installed).
•Route the Supervisor PIC cables through the Supervisor PIC cable management bracket and
chassis-mounted fiber/cable routing guide.

Installing the QSFP+ or QSFP28 Transceiver Modules in the Supervisor PIC
The 40-Gigabit (GE) QSFP+ and 100 Gigabit (QSFP28) transceiver module is a hot-swappable, parallel
fiber-optical module with four independent optical transmit and receive channels. These channels can terminate
in another 40-Gigabit QSFP+ transceiver, or the channels can be broken out to four separate 10-Gigabit SFP+
transceivers. The QSFP+ transceiver module connects the electrical circuitry of the system with an optical
external network.
The following figure shows the 40-Gigabit optical QSFP+ transceiver. The transceiver is used primarily in
short reach applications in switches, routers, and data center equipment where it provides higher density than
SFP+ modules. The 100-Gigabit optical QSFP28 transceiver is similar to the 40-Gigabit optical QSFP
transceiver.

Electrical connection to the module circuitry340GBASE QSFP+ transceiver body1
Bail-clasp latch2
The QSFP+ or QSFP28 transceiver module can have either a bail-clasp latch or a pull-tab latch. Installation
procedures for both types of latches are provided.
Before You Begin
Do not install or remove the QSFP28 module with fiber-optic cables still attached to it. Doing so may
damage cables, cable connectors, or the optical interfaces and may interfere with the QSFP28 module
latching properly into its socket connector. Disconnect all cables before removing or installing an QSFP28
module.
Caution
The QSFP+ or QSFP28 transceiver module is a static-sensitive device. Always use an ESD wrist strap or
similar individual grounding device when handling QSFP+ or QSFP28 transceiver modules or coming
into contact with system modules.
Caution
•Attach an ESD-preventive wrist strap to your wrist and connect the other end to the grounding lug
connected to the chassis.

Installing the QSFP+ or QSFP28 Transceiver Modules in the Supervisor PIC

•You must use the supported QSFP28 modules. The following QSFP28 modules are supported on the
Supervisor PIC:
◦QSFP-100G-SR4-S
◦QSFP-100G-LR4-S
◦QSFP-40G-SR4 with breakout cable
◦QSFP-4x10G-LR-S with breakout cable
Required Tools and Equipment
•Wrist strap or other personal grounding device to prevent ESD occurrences.
•Antistatic mat or antistatic foam to set the transceiver on.

•Fiber-optic end-face cleaning tools and inspection equipment.
Step 1 Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack.
Step 2 Remove the QSFP+ or QSFP28 transceiver module from its protective packaging.
Step 3 Check the label on the QSFP+ or QSFP28 transceiver module body to verify that you have the correct model for your
network.
Step 4 For optical QSFP+ or QSFP28 transceiver modules, remove the optical bore dust plug and set it aside.
Step 5 For QSFP+ or QSFP28 transceiver modules equipped with a pull-tab, hold the transceiver so that the identifier label is
on the top.
Step 6 For QSFP+ or QSFP28 transceiver modules equipped with a bail-clasp latch, keep the bail-clasp aligned in a vertical
position.
Step 7 Align the QSFP+ or QSFP28 transceiver module in front of the module’s transceiver socket opening and carefully slide
the QSFP+ or QSFP28 transceiver into the socket until the transceiver makes contact with the socket electrical connector
(see the figure below).
Figure 5: Installing the 40-Gigabit QSFP+ or 100-Gigabit QSFP28 Transceiver Module (Optical Transceiver Equipped with a Bail-Clasp
Latch Shown)
Step 8 Press firmly on the front of the QSFP+ or QSFP28 transceiver module with your thumb to fully seat the transceiver in
the module’s transceiver socket (see the below figure).

Step 9 For optical QSFP+ or QSFP28 transceiver modules, reinstall the dust plug into the QSFP+ or QSFP28 transceivers optical
bore until you are ready to attach the network interface cable. Do not remove the dust plug until you are ready to attach
the network interface cable.
What to Do Next
•Verify if the QSFP+ or QSFP28 module is seated and latched properly. Grasp the QSFP+ or QSFP28
module and try to remove it without releasing the latch. If the QSFP+ or QSFP28 module cannot be
removed, it is installed and seated properly. If the QSFP+ or QSFP28 module can be removed, reinstall
it.
•Connect fiber-optic cable to the QSFP+ or QSFP28 port.
