Precautions specific to the management modules
Be sure to perform the following procedures before you remove or replace a management module.
• Be sure to back up the configuration before you replace the management module by following the steps in Backing up the
configuration on page 73.
• The management module is sensitive to electrostatic discharge (ESD). When working with any Extreme module, use correct
electrostatic discharge (ESD) procedures.
• Any slot that is not occupied by a management module should be occupied by a filler panel to ensure correct cooling of the
chassis and protection from dust.
• Wear a wrist grounding strap connected to chassis ground (if the device is plugged in) or a bench ground. Refer to ESD ground
strap connection points on page 88 for the location of the ESD jack.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
• Store ESD-sensitive components in anti-static packaging.
CAUTION
Static electricity can damage the chassis and other electronic devices. To avoid damage, keep static-sensitive
devices in their static-protective packages until you are ready to install them.
• CAUTION
The 1GbE Management Port is suitable for connection to intrabuilding or unexposed wiring or cabling only. The
1GbE Management Port MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring.
These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE, Issue 6) and require isolation from the exposed OSP cabling. The addition of Primary Protectors
is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
ESD ground strap connection points
Many device components, such as interface modules, management modules, or switch fabric modules, require the use of an electrostatic
discharge (ESD) ground strap before removal or insertion.
Connect the ESD ground strap to the chassis as shown in the following figures. You can connect the strap to the connection on either the
front or back of the chassis.
