The 7750 SR ESA 100G extends the level of networking functionality and
generalized processing for IP/MPLS routing applications and integrated services on
the Nokia 7750 Service Router (SR).
The 7750 SR ESA 100G is supported by 7750 SR-s eXpandable Media Adapter
(XMA-s), Input/Output Module (IOM-s), and 7750 SR IOM line cards. It is directly
connected to the 7750 SR at 100G interface speeds, using QSFP optical
transceivers in the SR system and on the ESA NIC.
For more information about which specific 7750 SR interface cards support
connections to the 7750 SR ESA 100G, refer to SR OS Software Release Notes.
The chassis arrives fully assembled and must be installed in a rack; see section 4.

3 Site Preparation
This chapter describes site preparation for the 7750 SR ESA 100G and includes the
following topics:
•Safety Warnings, section 3.1
•Site Selection, section 3.2
•Installation Locations, section 3.3
•Ethernet Cabling, section 3.4
For detailed information about site preparation guidelines and equipment protection,
refer to the Best Practices for Improving Equipment Protection and Longevity guide,
located in the Nokia Documentation Center.
3.1 Safety Warnings
Danger:
• Only electrical service personnel should perform wiring and cabling to the system.
• All power to the equipment rack or cabinet should be disconnected before the
installation.
• Power cables must meet the local electric code requirements.
• The PSU on/standby switch is not intended to be used as the chassis ON/OFF switch.
Unplug the power cord from the power source and disconnect the cord from the
receptacle on the PSU to remove power.

Release 20.5
3HE 16094 AAAA TQZZA Issue: 01
3.2 Site Selection
The 7750 SR ESA 100G should be mounted in a standard 19-inch equipment rack.
The site should be a weather-protected and temperature-controlled location, and
should include the following criteria:
• maintain the site temperature within 41°F to 104°F (5°C to 40°C) and its humidity
within 5 to 85%, non-condensing, for the 7750 SR ESA 100G
• provide adequate space on the front, rear, and two sides of the chassis to enable
servicing and proper airflow
• ensure a secure environment in which only authorized and trained service
personnel are allowed to service the unit (IEC 60950 safety requirement)
Warning:
• The chassis is suitable for installation as part of the Common Bonding Network (CBN)
or an Isolated Bonding Network (IBN).
• The chassis is suitable for installation in Network Telecommunication Facilities or
locations where the NEC applies.
• All bare conductors must be coated with an appropriate antioxidant compound before
connections are made. All unplated connectors, braided strap, and bus bars must be
brought to a bright finish and then coated with an antioxidant before connecting them.
• When making the primary ground connection, a star washer must be used for
antirotation.
• When connecting the device to the rack frame, use thread-forming screws and paint-
piercing washers. The ground lug is secured to the frame and EUT by screws tightened
to a torque of 58 to 68 lbf-in (6.55 to 7.68 N·m).
• The equipment under test (EUT) is specified for DC-I power configurations. The battery
returns must remain isolated until they reach the main power bus.
• The 7750 SR ESA 100G with DC power supply should be installed only in restricted
access areas (such as dedicated equipment rooms and electrical closets) in
accordance with Articles 110-26 and 110-27 of the most recent National Electrical
Code ANSI/NFPA 70.

3.3 Installation Locations
The 7750 SR ESA 100G is intended to be installed in facilities that provide weather
protection and an extended temperature-controlled environment.
The 7750 SR ESA 100G is not intended for installation outdoors.
The 7750 SR ESA 100G is designed to work in an environment equivalent to a
modern office building, where protection is provided from contaminants, including
mold growth, precipitation, volatile or corrosive chemicals, hygroscopic dust, insects,
pests, or vermin entering the product.
When a 7750 SR ESA 100G is installed in an outside plant, such as a cell site, hut,
cabinet, or outside plant enclosure, it must be installed in an environment where,
except during installation and servicing, the compartment is sealed or properly
filtered.
The product must be protected from ingress of contaminants such as outside air,
conductive pollution, volatile or corrosive elements (for example, salt-laden air),
hygroscopic dust, insects, pests, or vermin.
The humidity levels in the cabinet must be controlled to ensure a relative humidity
level between 5% and 85% (non-condensing) with short-term levels of 10% to 95%
(non-condensing). (Short-term is a period of less than 96 consecutive hours and a
total of no more than 15 days per year. This is equivalent to 360 hours per year, with
short-term periods occurring no more than 15 times per year.) The dew point
threshold in the cabinet must not be crossed.
Note: The 7750 SR ESA 100G CPU monitors temperature sensors throughout the system.
If an over-temperature condition is detected, the control plane processor will perform a reset
and reboot the system. At boot time, the system checks the temperature sensors before
proceeding with a full system boot. At boot time, the system fans are always running at the
highest speed and are ordinarily throttled down after system boot based on the temperature
sensor readings. If the temperature at boot-up is outside proper operating limits, the CPU
will reboot and restart the system boot sequence. If the temperature sensors are within the
proper operating range at system boot-up, the system startup will proceed.
Warning: Follow the equipment rack manufacturer’s instructions for proper rack installation.
Failure to comply with the requirements and the location requirements outlined in this
section may impede proper airflow and may result in the system overheating.
