Prepare for Installation

Review Installation Guidelines

Take care when connecting units to the supply circuit so that wiring is not overloaded.

•

This equipment must be grounded. 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.

To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the

•

handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to
support the weight of the unit.

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution

•

when servicing.

When installing or replacing the unit, the ground connection must always be made first and disconnected

•

last.

The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide

•

the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams

•

or view directly with optical instruments.

Review Installation Guidelines

Before installing the chassis, verify that these guidelines are met:

Site is properly prepared so that there is sufficient room for installation and maintenance. For specifications

•

on the clearances required for chassis installation, see Clearance Requirements, on page 62.

Operating environment is within the ranges listed in Environmental and Physical Specifications, on

•

page 59

Chassis is mounted at the bottom of the rack if it is the only unit in the rack.

•

When mounting the chassis in a partially filled rack, load the rack from the bottom to the top with the

•

heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the

•

chassis in the rack.

Airflow around the chassis and through the vents is unrestricted.

•

Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting

•

fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.

Guidelines for Connecting Ports

Depending on the chassis and installed line cards, you can use Quad Small Form-Factor Pluggable Plus
(QSFP+), QSFP28, SFP, SFP+, and RJ-45 connectors to connect the ports on the line cards to other network
devices.

To prevent damage to the fiber-optic cables that can separate from their cables, Cisco recommends that you
keep the transceivers disconnected from their fiber-optic cables when installing the transceiver in the line
card. Before removing such a transceiver from the router, remove the cable from the transceiver.

To maximize the effectiveness and life of your transceivers and optical cables, do the following:

CHAPTER 4

Wear an ESD-preventative wrist strap that is connected to an earth ground whenever handling transceivers.

•

The router is typically grounded during installation and provides an ESD port to which you can connect
your wrist strap.

Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions

•

can shorten its useful life.

Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to

•

prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should
be kept below 0.35 dB.

Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.

Installing and Removing QSFP+/QSFP28 Transceiver Modules

Installing and Removing QSFP+/QSFP28 Transceiver Modules

This section provides the installation, cabling, and removal instructions for the 40-Gigabit Quad Small
Form-Factor Pluggable Plus (QSFP+) and 100 Gigabit (QSFP28) transceiver modules. The modules are
hot-swappable input/output (I/O) devices that connect the system’s module port electrical circuitry with either
a copper or a fiber-optic network.

Overview

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

Verify Chassis Installation

After installing the NCS 5500 Series Chassis, you can use the show commands to verify the installation and
configuration. If any issue is detected, take corrective action before making further configurations.

Step 1

Step 2

Step 3

show inventory

Example:

sysadmin-vm:0_RP0 #show inventory

Displays information about the field replaceable units (FRUs), including product IDs, serial numbers, and version IDs.

show environment

Example:

sysadmin-vm:0_RP0 #show environment

Displays all of the environment-related router information.

show environment temperature

Example:

sysadmin-vm:0_RP0 #show environment temperature

Displays temperature readings for card temperature sensors. Each system controller, route processor, line card, and
fabric card has temperature sensors with two thresholds:

Minor temperature threshold-When a minor threshold is exceeded, a minor alarm occurs and the following actions

•

occur for all four sensors:

Displays system messages

◦

Sends SNMP notifications (if configured)

◦

Log environmental alarm event that can be reviewed by running the show alarm command.

◦

Major temperature threshold-When a major threshold is exceeded, a major alarm occurs and the following actions

•

occur:

For sensors 1, 3, and 4 (outlet and onboard sensors), the following actions occur:

•

Displays system messages.

•

Sends SNMP notifications (if configured).

•

Hardware Installation Guide for Cisco NCS 5500 Series Fixed-Port Routers

Verify Chassis Installation

Logs environmental alarm event that can be reviewed by running the show alarm command.

•

For sensor 2 (intake sensor), the following actions occur:

•

If the threshold is exceeded in a switching card, only that card is shut down.

•

If the threshold is exceeded in an active route processor card with HA-standby or standby present, only

•

that route processor card is shut down and the standby route processor card takes over.

If you do not have a standby route processor card in your router, you have up to 2 minutes to decrease

•

the temperature. During this interval, the software monitors the temperature every 5 seconds and
continuously sends system messages as configured.
