Removing an Expansion Module from an EX4600 Switch
Before you begin removing an expansion module from the switch:
• Ensure that you have taken the necessary precauons to prevent electrostac discharge (ESD)
damage (see Prevenon of Electrostac Discharge Damage ).
• If there are any transceivers installed in the expansion module, remove them before you remove the
expansion module. For instrucons on removing transceivers, see Remove a Transceiver .
Ensure that you have the following parts and tools available:
• ESD grounding strap
• Phillips screwdriver, number 2
• A replacement oponal module or cover panel
• An anstac bag or anstac mat
The expansion modules used in EX4600 switches are hot-removable and hot-insertable eld-replaceable
units (FRUs): You can remove and replace them without powering o the switch.
The EX4600 is congured for the QFX-EM-4Q by default, but any combinaon of the two modules is
supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F
is inserted instead of the default QFX-EM-4Q, the PFE reboots and all of the interfaces on the switch
and expansion module temporarily go down. Likewise when an EX4600-EM-8F is running on the
EX4600 and it is swapped with a QFX-EM-4Q, all of the interfaces temporarily go down, which can
cause a short disrupon in trac.
