Juniper PTX Series Quick Start

Optical Inline Amplifier Quick Start
See the complete PTX Series documentation at
http://www.juniper.net/techpubs/.
To install, connect power to, and configure the Juniper Networks
Optical Inline Amplifier, you need:
Electrostatic discharge (ESD) grounding strap (not provided).
Four screws to secure the chassis and mounting brackets to the
rack (not provided).
Screwdriver appropriate for the rack-mounting screws (not provided).
Two power cords with plugs appropriate for your geographical location (provided with
the AC model).
Two DC power connectors (provided with the DC model).
Power cable or cables appropriate for your geographical location available to connect
DC power to the optical ILA (not provided).
RJ-45 cable and RJ-45 to DB-9 serial port adapter (provided).
Management host, such as a PC laptop, with a serial port (not provided).
(Optional) Grounding cable with lug, screws, and washers (not provided).
(Optional) 23-in. mounting brackets (provided).
Part 1: Mount the Optical ILA
The optical inline amplifier (optical ILA) can be mounted on a two-post rack.
NOTE: Place the rack in its permanent location, allowing adequate clearance for airflow
and maintenance, and secure it to the building structure. If you are mounting multiple
units in the rack, mount the heaviest unit at the bottom and mount the other units from
bottom to top in order of decreasing weight. The DC-powered optical ILA weighs 11.8 lb
(5.35 kg) and the AC-powered optical ILA weighs 11.7 lb (5.30 kg).
To mount the optical ILA on two posts of a rack by using the provided mounting kit:
1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
2. Position the optical ILA in such a manner that the FRUs are next to the hot aisle.
NOTE: The 19-in. brackets are attached to the optical ILA when they are shipped. If you
want to attach the 23-in. brackets, unscrew the 19-in. brackets from the chassis, and
attach the 23-in. brackets by using the same screws.
3. Use four mounting screws (and cage nuts and washers if your rack requires them) to
attach the optical ILA to the rack as shown in the illustration.
4. Tighten the screws.
5. (Optional) Attach a grounding cable to earth ground and then attach it to the chassis
grounding point.
Part 2: Connect Power to the Optical ILA
The optical ILA is supplied with two factory-installed power supplies. For instructions on
connecting DC power, see the installation instructions in the Optical Inline Amplifier
Hardware Guide.
To connect power to an optical ILA with AC power supplies:
1. To prevent damage to the equipment caused by static discharge, attach an ESD
grounding strap to your bare wrist, and connect the strap to an approved site ESD
grounding point.
2. Ensure that the power supplies are fully inserted in the chassis and the latches are
secure.
3. If the AC power source outlet has a power switch, set it to the off (O) position.
4. Insert the coupler end of the power cord into the AC power cord inlet on the AC
power supply faceplate.
5. Open the power cord retainer by pressing the protruding tab and prying it open. Wrap
the power cord retainer around the AC power cord and push the cable clamp through
the hole to tighten.
