Maintenance Safety
Take the following precautions:
●
Use only original accessories and/or components approved for use with this system. Failure to
observe these instructions may damage the equipment or even violate required safety and EMC
regulations.
●
The chassis cover should only be removed by Extreme Networks personnel. There are no customer
serviceable components in this system. Repairs to the system must be performed by an Extreme
Networks factory service technician.
●
The power on button for the system may not turn off all system power. To remove power from the
system, you must unplug all power cords from wall outlets. The power cord is the disconnect device
to the main power source.
●
Disconnect all power before removing the back panel of any Extreme Networks switch, unless
otherwise instructed by a product specific maintenance procedure.
●
Disconnect all power cords before working near power supplies, unless otherwise instructed by a
maintenance procedure.
●
When handling modules, optic devices, power supplies, or other modular accessories put on the
electrostatic discharge (ESD) preventive wrist strap to reduce the risk of electronic damage to the
equipment. Leave the ESD-preventive wrist strap permanently attached to the chassis so that it is
always available when you need to handle ESD-sensitive components.
●
Install all cables in a manner that avoids strain. Use tie wraps or other strain relief devices.
●
Replace power cord immediately if it shows any signs of damage.
General Safety Precautions
Follow these guidelines:
●
Do not attempt to lift objects that you think are too heavy for you.
●
When installing in rack, caution should be taken to load heavier devices in lowest portions of rack to
avoid a top heavy hazard.
●
For Summit desktop switches, do not place a monitor or other objects on top of the equipment. The
chassis cover is not designed to support weight.
●
Only use tools and equipment that are in perfect condition. Do not use equipment with visible
damage.
●
Protecting ESD: To protect ESDs always wear a wristband before carrying out any work on PC
boards and modules. Transport PC boards only in electrostatic packaging. Always place PC boards
on a grounded surface before working on them.
●
Laying cables: Lay cables so as to prevent any risk of these cables being damaged or causing
accidents, such as tripping.
