Removing a Virtual Chassis Module from a J-EX4500 Switch
The Virtual Chassis module is installed horizontally on the rear panel of the switch. See
“Rear Panel of a J-EX4500 Switch” on page 9. Use the procedure described in this topic
to remove the module from the switch chassis.
CAUTION: Operating a J-EX4500 switch without the Virtual Chassis module
installed is not supported. You cannot start the switch unless the Virtual
Chassis module is installed in the chassis.
Before you begin removing the Virtual Chassis module from the switch:
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage (see “Prevention of Electrostatic Discharge Damage” on page 186).
• Have instructions and tools for removing the fan tray. See “Removing a Fan Tray from
a J-EX4500 Switch” on page 130.
Ensure that you have the following parts and tools available:
•
ESD grounding strap
•
Phillips screwdriver, number 2
• A replacement Virtual Chassis module. (Install the replacement module immediately
after removing the module. Operating the switch without this module is not supported.)
•
An antistatic bag or antistatic mat
NOTE: You must remove the fan tray from the switch before removing the
Virtual Chassis module. See “Removing a Fan Tray from a J-EX4500 Switch”
on page 130.
To remove the Virtual Chassis module from the switch (see Figure 57 on page 134):
1.
Halt the switch using the request system halt CLI command:
user@switch>
