M7i Internet Router Quick Start

Quick Start Description
This Quick Start contains information you need to install and configure the router
quickly. For complete installation instructions, see the M7i Internet Router Hardware
Guide at http://www.juniper.net/techpubs/hardware/.
WARNING: This Quick Start contains a summary of safety warnings in “Safety
Warnings”on page 15. For a complete list of warnings for this router, including
translations, see the M7i Internet Router Hardware Guide at
http://www.juniper.net/techpubs/hardware/.
The M7i Internet Router is a complete routing system that provides ATM, channelized,
Ethernet, IP services, and SONET/SDH interfaces for large networks and network
applications, such as those supported by Internet service providers (ISPs).
Application-specific integrated circuits (ASICs), a definitive part of the router design,
enables the router to forward data at the high speeds demanded by current network
media.
The router accommodates up to four Physical Interface Cards (PICs). In addition to
the PICs, the Fixed Interface Card (FIC) provides two Fast Ethernet ports or one
Gigabit Ethernet port, depending on your configuration. The built-in tunnel interface
on the Compact Forwarding Engine Board (CFEB) provides tunnel services, and the
optional Adaptive Services Module (ASM) on the CFEB allows one or more services
to be configured on this interface.
The router provides very high throughput for any combination of PICs that does not
exceed 3.2 Gbps full duplex. A combination that exceeds this number is supported,
but constitutes oversubscription.
The router is shipped in a cardboard carton, secured with foam packing material.
The carton contains:
■One accessory box (the box to which this Quick Start is taped)
■One Juniper Networks router
■One Quick Start (this document)
Step 1: Prepare the Site
Before installing the router, read the site preparation guidelines in the M7i Internet
Router Hardware Guide to make sure that the site meets power, environmental, and
clearance requirements for the router.
Rack-Mounting Requirements
■You can install the router in a four-post rack or cabinet or an open-frame rack.
■The rack must be strong enough to support the weight of the fully configured
router, up to about 36.5 lb (16.6 kg). You can mount up to 21 M7i routers in a
Quick Start Description ■3
Quick Start Description

floor-to-ceiling rack. If you do so, the rack must be capable of supporting a
combined weight of over 766 lb (347 kg).
■The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 3.5 in. (8.9 cm) high, 18.2 in. (45.7 cm) deep, and 17.5 in.
(44.5 cm) wide. The mounting hardware extends the width to fit into standard
19-in. racks.
■For service personnel to remove and install hardware components, there must
be adequate space at the front and back of the router. At least 24 in. (61.0 cm)
both in front of and behind the rack or cabinet is required. NEBS GR-63
recommends at least 30 in. in front of the rack or cabinet.
■The rack or cabinet must have an adequate supply of cooling air:
■6 in. (15.2 cm) is required between the side of the router and any equipment
that produces heat.
■2.8 in. (7.1 cm) is required between the side of the router and any large
surface that does not produce heat, such as a wall.
■In a closed cabinet, there must be a minimum of 6 in. (15.2 cm) of
unobstructed airflow behind the router, or airflow baffles must be installed
to prevent recirculation of hot air and overheating.
■If the router is the only unit in the rack, mount it at the bottom of the rack.
■When mounting the router in a partially filled rack, load the rack from the bottom
to the top with the heaviest component at the bottom of the rack.

Figure 5: Connect External Devices and PIC Cables to Router
Connect a Management Console or Auxiliary Device
1. Turn off the power to the console or auxiliary device.
2. Plug the female end of the RS-232 serial connector into the CONSOLE or
AUX/MODEM port.
3. Use a 2.5 mm flat-blade screwdriver to tighten the screws on the connector.
4. Connect the other end of the cable to the console or auxiliary device.
Connect to a Network for Out-of-Band Management
1. Turn off the power to the networking device.
2. Plug one end of the Ethernet cable (with RJ-45/RJ-45 connectors) into the MGMT
port on the Routing Engine.
3. Plug the other end into the networking device.
Connect FIC and PIC Cables
WARNING: Do not look directly into a fiber-optic transceiver or into the ends of
fiber-optic cables connected to a transceiver. Fiber-optic transceivers contain laser
light sources that can damage your eyes.
Step 4: Connect External Devices and PIC Cables ■9
Step 4: Connect External Devices and PIC Cables

CAUTION: To prevent damage to fiber-optic transceivers and fiber-optic cables,
observe the following precautions:
■Do not leave a fiber-optic transceiver uncovered except when inserting or
removing cable. The safety plug keeps the port clean and prevents accidental
exposure to laser light.
■Do not bend fiber-optic cable beyond the maximum bend radius. An arc smaller
than a few inches in diameter can damage the cable and cause problems that
are difficult to diagnose.
■Do not let fiber-optic cable hang free from the connector.
■Do not allow fastened loops of cable to dangle, which stresses the cable at the
fastening point.
1. Make sure you have the appropriate cable for the FIC or PIC.
2. If you are connecting to a FIC or PIC with removable transceivers, make sure
the transceiver is installed.
3. If the transceiver is covered by a rubber safety plug, remove the plug.
4. If the cable connector is covered by a rubber safety cap, remove the cap.
5. Insert the appropriate cable connector into the cable connector port on the FIC
or PIC faceplate.
6. Arrange the cable in the cable management system to prevent it from dislodging
or developing stress points. Secure the cable so that it is not supporting its own
weight as it hangs to the floor. Place excess cable out of the way in a neatly
coiled loop in the cable management system. Placing fasteners on the loop helps
to maintain its shape.
Step 5: Connect Ground and Power Cables
NOTE: Connect each power supply to a separate external power source.
The M7i router uses either AC or DC power supplies. Perform the appropriate
procedure for each power supply in your router.
■Connect AC Power on page 10
■Connect DC Power on page 11
Connect AC Power
1. Locate the power cords shipped with the router, which should have a plug
appropriate for your geographical location.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis.
10 ■Step 5: Connect Ground and Power Cables
M7i Internet Router Quick Start

3. Verify that the switch on each power supply faceplate is in the OFF (O) position.
4. For each power supply:
a. Insert the appliance coupler end of a power cord into the appliance inlet on
a power supply faceplate.
b. Insert the plug into an AC power source receptacle.
c. Verify that the power cord does not block access to router components or
drape where people could trip on it.
Connect DC Power
CAUTION: You must ensure that power connections maintain the proper polarity.
The power source cables might be labeled (+) and (–) to indicate their polarity. There
is no standard color coding for DC power cables. The color coding used by the external
DC power source at your site determines the color coding for the leads on the power
cables that attach to the terminal studs on the power faceplate.
1. Make sure that there is no power flowing from the external power source, so
that the voltage across the leads of the power cables is 0 V. Ensure that there is
no chance that the cable leads might become active during the procedure.
2. For each power supply, verify that the power switch on the power supply faceplate
is in the OFF (O) position.
3. Connect the grounding cable to a proper earth ground for each external DC
power source, if it is not already connected.
4. Verify that a licensed electrician has attached the cable lug provided with the
router to the grounding cable
5. Using a number 2 Phillips screwdriver, remove the screw next to the grounding
symbol above the power supplies on the chassis rear. Secure the grounding cable
lug to the grounding point by reinstalling and tightening the screw.
6. Verify that a licensed electrician has attached a listed power cable lug to each
power source cable.
7. Loop the power cables through the hook located on the faceplate to the right of
the field-wiring terminals.
8. Depending on the type of power cable lugs used, loosen or remove the screws
on the field-wiring terminals.
9. Insert each power cable lug into the appropriate field-wiring terminal. Use a
number 1 Phillips screwdriver to secure the power cable lug. Turn the screw on
each field-wiring terminal clockwise, and apply between 8 lb-in. (0.9 Nm) and
9 lb-in. (1.02 Nm) of torque to each screw.
a. Insert the positive (+) source cable into the return terminal (labeled RTN).
b. Insert the negative (–) source cable into the input terminal (labeled –48).
10. Verify that the DC source power cabling and the grounding cabling are correct,
Step 5: Connect Ground and Power Cables ■11
Step 5: Connect Ground and Power Cables

11. Verify that the power cables are not touching or blocking access to router
components, and that they do not drape where people could trip on them.
12. Switch on the external circuit breakers to provide voltage to the DC power source
cable leads.
Figure 6: Connect the Power Cables to a DC Router
Step 6: Power On the Router
1. Verify that an external management device is connected to one of the Routing
Engine ports on the Routing Engine (AUX/MODEM, CONSOLE, or MGMT).
2. Turn on the power to the external management device.
3. Verify that the power supply is fully inserted in the chassis and the thumbscrews
on their faceplates are tightened.
4. Verify that the power cord or cables are properly connected:
■Verify that the ends of the AC power cord are firmly plugged into the
appliance inlet on the power supply faceplate and the external power source
receptacle.
■Verify that the source DC power cables are connected to the appropriate
terminal on the power supply faceplate: the positive (+) source cable to the
return terminal (labeled RTN) and the negative (–) source cable to the input
terminal (labeled –48V).
5. Press the power switch on the power supply faceplate to the ON (|) position.
6. Monitor the startup procedure on the external management device to ensure
that the system boots properly.
12 ■Step 6: Power On the Router

Safety Warnings
WARNING: See installation instructions before connecting the router. This is a
summary of safety warnings. For a complete list of warnings for this router, including
translations, see the M7i Internet Router Hardware Guide at
http://www.juniper.net/techpubs/.
WARNING: The intra-building port(s) of the router is suitable for connection to
intrabuilding or unexposed wiring or cabling only. The intra-building port(s) of the
router 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, Issue 4) 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.
CAUTION: Before removing or installing components of a router, attach an ESD strap
to an ESD point and place the other end of the strap around your bare wrist. Failure
to use an ESD strap could result in damage to the router.
CAUTION: An external Surge Protective Device (SPD) should be used at the AC input
of the router.
■Only trained and qualified personnel should install or replace the router.
■Perform only the procedures described in this quick start or the M7i Internet
Router Hardware Guide. Other services should be performed by authorized service
personnel only.
■Read the installation instructions before you connect the router to a power source.
■Before installing the router, read the guidelines for site preparation in the M7i
Internet Router Hardware Guide to make sure that the site meets power,
environmental, and clearance requirements for the router.
Safety Warnings ■15
Safety Warnings

■When installing the router, do not use a ramp inclined at more than 10 degrees.
■Manually installing the router requires two people to lift. To prevent injury, keep
your back straight and lift with your legs, not your back. Do not attempt to lift
the chassis by the power supply handles.
■The router should be mounted at the bottom of the rack if it is the only unit in
the rack.
■When mounting the router 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 router in the rack.
■When removing or installing an electrical component, always place it
component-side up on a flat antistatic surface or in an electrostatic bag.
■When you install the router, the ground connection must always be made first
and disconnected last.
■Wire the DC power supply using the appropriate lugs. When connecting power,
the proper wiring sequence is ground to ground, +RTN to +RTN, then -48 V to
-48 V. When disconnecting power, the proper wiring sequence is -48 V to -48 V,
+RTN to +RTN, then ground to ground. The ground wire should always be
connected first and disconnected last.
■Do not work on the system or connect or disconnect cables during electrical
storms.
■Before working on equipment that is connected to power lines, remove jewelry,
including rings, necklaces, and watches. Metal objects heat up when connected
to power and ground and can cause serious burns or become welded to the
