technicians to reset the switch, as follows:

•

Press

Reset

: The switch resets and reloads the configuration files.

•

Press and hold

Fans

Four hot-swap fan modules cool the switch unit. If an individual fan module fails,
the other fans continue to run, and the switch unit continues to operate normally.
You can replace a hot-swap fan module while the switch is operating.

Fan operation and internal temperatures are monitored. If the air temperature
exceeds a desired threshold, the environmental monitor displays warning
messages.

Note: If a fan fails, the maximum operating temperature drops from +40ºC to +35ºC

(104ºF to 95ºF)

The Service ( ! ) LED flashes and the Fan LED flashes if there is a failure of one or
more fan modules. The failed fan module LED (rear panel) flashes to indicate a
failure.

AC power supply

The G8264T has two hot-swap redundant 750W AC power supplies. Each internal
power supply has an individual IEC 320 power connector on the rear panel. The
power cord attaches to a universal grounded AC power source. You can replace a
hot-swap power supply module without powering off the switch or disrupting switch
functions.

for five seconds: The switch resets and configures all

.

DANGER

Hazardous voltage, current, or energy levels are present inside any
component that has this label attached. Do not open any cover or barrier
that contains this label.

(L001)

Each power supply can be connected to a separate AC circuit to mitigate the risk of
down time during a power failure. When used in a redundant configuration, the dual
power supplies have a load-sharing capability that allows each supply to operate at
approximately 50% of full load. Using redundant power can minimize the power
disruption during a power supply failure and extend the expected lifetime of each
supply by operating normally in a conservative power mode.

There is no power switch on the G8264T; the switch unit powers up when power is
supplied through the power cord(s). Power cords must be ordered separately.

18 RackSwitch G8264T: Installation Guide

Handling static-sensitive devices

Attention:

avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following
precautions:

•

Limit your movement. Movement can cause static electricity to build up around
you.

•

The use of a grounding system is recommended. For example, wear an
electrostatic-discharge wrist strap, if one is available.

•

Handle the device carefully, holding it by its edges or its frame.

•

Do not touch solder joints, pins, or exposed printed circuitry.

•

Do not leave the device where others can handle and damage it.

•

While the device is still in its static-protective package, touch it to an unpainted
metal part of any unpainted metal surface on a grounded rack component in the
rack in which you are installing the device, for at least 2 seconds. This drains
static electricity from the package and from your body.

•

Remove the device from its package and install it directly into the switch without
setting it down. If it is necessary to set down the device, put it back into its
static-protective package. Do not place the device on a switch cover or on a
metal surface.

•

Take additional care when you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.

Static electricity can damage the switch and other electronic devices. To

Particulate contamination

Attention:

Airborne particulates (including metal flakes or particles) and reactive
gases acting alone or in combination with other environmental factors such as
humidity or temperature might pose a risk to the device that is described in this
document. Risks that are posed by the presence of excessive particulate levels or
concentrations of harmful gases include damage that might cause the device to
malfunction or cease functioning altogether. This specification sets forth limits for
particulates and gases that are intended to avoid such damage. The limits must not
be viewed or used as definitive limits, because numerous other factors, such as
temperature or moisture content of the air, can influence the impact of particulates
or environmental corrosives and gaseous contaminant transfer. In the absence of
specific limits that are set forth in this document, you must implement practices that
maintain particulate and gas levels that are consistent with the protection of human
health and safety. If IBM determines that the levels of particulates or gases in your
environment have caused damage to the device, IBM may condition provision of
repair or replacement of devices or parts on implementation of appropriate remedial
measures to mitigate such environmental contamination. Implementation of such
remedial measures is a customer responsibility.
