T320 Quick Start Description

Step 1: Prepare the Site for T320 Installation
Before installing the router, make sure that the site meets power, environmental, and
clearance requirements for the router. See the site preparation guidelines in the T320
Core Router Hardware Guide.
•Rack-Mounting Requirements on page 4
•Tools Required on page 5
Rack-Mounting Requirements
•You can install the router in a four-post rack or cabinet, or an open-frame rack.
•The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 25.13 in. (63.82 cm) high, 31 in. (78.7 cm) deep, and 17.4 in. (44.2
cm) wide. The front-mounting flanges and center-mounting brackets extend the width
to fit into standard 19-in. (48.3 cm) racks.
•The rack must be strong enough to support the weight of the fully configured router.
Each router can weigh up to 369.9 lb (167.8 kg) if fully configured. Up to three routers
can be installed into one standard (44-U) rack that can handle their combined weight,
which can be greater than 1100 lb (499 kg).
•For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the router. Allow at least 24 in. (61.0 cm) both
in front of and behind the router. NEBS GR-63 recommends at least 30 in. in front of
the router.
•The rack or cabinet must have an adequate supply of cooling air.
•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.

5. Tighten the screws on the connectors.
Connect to a Network for Out-of-Band Management
NOTE: Before you can use the Ethernet management port to connect to a
network for out-of-band management, you must perform the initial Junos
OS configuration after the router has been powered on. See “Step 7: Perform
Initial Software Configuration” on page 22.
1. Locate the appropriate cable and connector.
2. Plug one of the Ethernet cable connectors into the ETHERNET port on the CIP.
3. Plug the other end into the networking device.
Connect the PIC Cables
WARNING: Do not look directly into the ends of fiber-optic cables or into the
transceivers on the interface faceplate. Fiber-optic transceivers emit laser
light that can damage your eyes.
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 its 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. Identify the appropriate cable to be connected to each PIC. Remove any rubber safety
plugs from the cable receptacles, and insert the appropriate cable connector into the
PIC cable receptacle.
2. Drape the cable over the bobbins of the cable management system to protect them
from bending past their recommended bend radius.

2. Power On the Router on page 21
Connect the DC Power Cables
The T320 router uses DC power supplies.
Perform the procedure for each power supply in your router:
1. Make sure that the voltage across the DC power source cable leads is 0 V and that
there is no chance that the cable leads might become active during installation.
2. Verify that a licensed electrician has attached the cable lugs provided with the router
to the DC power cables.
3. Verify that the switch on the power supply faceplate is in the OFF (O) position.
4. Remove the clear plastic cover from the faceplate of each power supply.
5. Attach the power cable lugs to the terminal studs on the power supply faceplate.
Secure the power cable lugs to the terminal studs, first with washers, then with the
nuts. Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.
a. Connect the positive (+) cable lug to the RTN (return) terminal.
b. Connect the negative (–) cable lug to the -48V (input) terminal.
6. Attach the cable restraints to the edge of the power supply faceplate to hold the
power cables in place.
7. Verify that the power cables are connected correctly, that they are not touching or
blocking access to router components, and that they do not drape where people could
trip on them.
8. Replace the clear plastic cover.
