Precautions specific to the interface modules
Before removing or replacing an interface module, make a note of the following precautions.
• If you are replacing a line card with a different type of line card, after removing the original line card, you must enter the no
linecard slot-number command to clear the current slot configuration. You must also select the new line card type using the
linecard slot_number linecard_type command before installing the new line card. For more detailed command steps, refer to
Inserting an interface module on page 97.
• Install a new line card only if it is supported by the firmware running in the chassis. Inserting a line card into a chassis running
firmware that does not support the line card may result in unexpected behavior. The list of supported line cards is provided in
Supported hardware and software on page 11.
• Any slot that is not occupied by a line card should be occupied by a filler panel to ensure correct cooling of the chassis and
protection from dust.
The line cards are sensitive to electrostatic discharge (ESD). When working with any Extreme module, use correct electrostatic discharge
(ESD) procedures.
• 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.
Time and items required for installation and
replacement
The replacement procedure for each interface module takes less than 10 minutes. Removing and restoring transceivers and cables may
take longer depending on how many must be changed. The following items are required for the interface module replacement:
• Replacement interface module or filler panel
• #2 Phillips screwdriver
• SFP+ or QSFP28 transceivers (as needed)
• Optical and copper cables (as needed)
