14 RackSwitch G8052 Installation Guide
Chapter 1. The RackSwitch G8052
Introduction
This Installation Guide provides information about the Lenovo
G8052 (referred to as G8052 throughout this document).
The G8052 is a 1U rack-mountable aggregation switch with unmatched line-rate
Layer 2 and Layer 3 performance. The G8052 uses a wire-speed, non-blocking
switching fabric that provides simultaneous wire-speed transport of multiple packets
at low latency on all ports.
The G8052 contains the following switching ports:
•
Forty-eight Gigabit Ethernet (GbE) RJ-45 ports
•
Four 10 GbE Small Form Pluggable Plus (SFP+) ports
SFP+ ports
Direct-Attach Cables (DACs), and QSFP+ ports can be populated with optical
QSFP+ modules or DACs
The G8052 is rack-mountable in either the horizontal or vertical direction, depending
on your application. Mounting options are available for a variety of rack systems (as
described in Chapter 3, “Installing G8052 Hardware and Options.”
For superior reliability, the G8052 uses redundant, hot-swap power supply modules
and four hot-swap fan modules. Module options are available for either front-to-rear
airflow, or rear-to-front airflow.
You can manage the switch through the local console port, or through a remote
network connection, a Web browser-based interface, or SNMP-based network
management software. For more information, see Chapter 5, “Initializing the G8052”
on page 69.

Mini-USB Serial Console Port
The mini-USB port on the front management panel is available for switch console
management. The port operates using RS-232 serial communications. A compatible
console cable kit is included with the switch.
To connect a computer or terminal to the switch using the included kit, first connect
the console cable to the mini-USB port on the front panel. Connect one end of the
Category 5 patch cable to the RJ-45 port on the console cable, and the other end of
the patch cable to the RJ-45-to-DB9 adapter (see the following illustration).

Some laser products contain an embedded Class 3A or Class 3B laser
diode. Note the following.
Laser radiation when open. Do not stare into the beam, do not view directly
with optical instruments, and avoid direct exposure to the beam.

Four 10 GbE SFP+ ports are available on the front panel . These ports accept
supported optical or copper SFP or SFP+ transceivers, or DACs. Transceivers must
be purchased separately.

Fans
For cooling, the rear panel of the G8052 has four bays for hot-swap fan modules.
Four fan modules are required for redundancy. When four fan modules are used, if
there is a failure of one of the four fans, the switch reports the condition, the other
fans continue to run, and the switch continues to operate normally. You can replace
the failed hot-swap fan module while the switch is operating. If a second fan fails,
the switch reports the condition and shuts down to prevent overheating.
Fan operation and internal temperatures are monitored. If the air temperature
exceeds a desired threshold, the environmental monitor displays warnings.
Note: If a fan fails, the maximum operating temperature drops from +40°C (104°F)
to +35°C (95°F).
Fan LEDs
Fan LED indicators are located on the rear panel of the switch, on the individual fan
modules. The following table describes the fan module LED behavior.

The rear panel of the G8052 has two bays for hot-swap power supply modules.
Each power supply module has an individual IEC 320 C14 power connector. The
power cord attaches to a universal grounded AC power source.
Statement 5
CAUTION:
The power control button on the device and the power switch on the power
supply do not turn off the electrical current supplied to the dev ice. The device
also might have more than one power cord. To remove all electrical current
from the device, ensure that all power cords are disco nnected from the powe r
source.

Statement 31
DANGER
Electrical current from power, telephone, and communication cables is
hazardous.
To avoid a shock hazard:
•
Do not connect or disconnect any cables or perform installation,
maintenance, or reconfiguration of this produ ct during an electrical storm.
•
Connect all power cords to a properly wired and grounded power source.
•
Connect to properly wired power sources any equipment that will be
attached to this product.
•
When possible, use one hand only to connect or disconnect signal cables.
•
Never turn on any equipment when there is evidence of fire, water, or
structural damage.
•
Disconnect the attached ac power cords, dc power sources, network
connections, telecommunications systems, and seria l cables before you
open the device covers, unless instructed otherwise in the installation
and configuration procedures.
•
Connect and disconnect cables as described in th e following table when
you install, move, or open covers on this product or attached devices.
To Connect:
1. Turn OFF all power sources and
equipment that is to be attached to
this product.
2. Attach signal cables to the product.
3. Attach power cords to the product.
– For ac systems, use appliance
inlets.
– For dc systems, ensure correct
polarity of -48 V dc connections:
RTN is + and -48 V dc is -. Earth
ground should use a two-hole
lug for safety.
4. Attach signal cables to other
devices.
5. Connect power cords to their
sources.
6. Turn ON all the power sources.
Two power supply modules are required for redundancy. Each power supply can be
connected to a separate circuit to mitigate the risk of down-time during a localized
power failure. When used in a redundant configuration, the dual power supplies
have a load-sharing capability that enables each power supply to operate at
approximately 50 percent of full load.
To Disconnect:
1. Turn OFF all power sources and
equipment that is to be attached to
this product.
– For ac systems, remove all
power cords from the chassis
power receptacles or interrupt
power at the ac power
distribution unit.
– For dc systems, disconnect dc
power sources at the breaker
panel or by turning off the power
source. Then, remove the dc
cables.
2. Remove the signal cables from the
connectors.
3. Remove all cables from the
devices.
