Removing An Uplink Module From An Ex4300 Switch - Juniper EX4300 Series Hardware Manual

Removing an Uplink Module from an EX4300 Switch

Before you begin removing an uplink module from the switch:
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD)
damage (see Prevention of Electrostatic Discharge Damage
• If there are any transceivers installed in the uplink module, remove them before you remove the
uplink module. For instructions on removing transceivers, see
Ensure that you have the following parts and tools available:
• ESD grounding strap
• Phillips (+) screwdriver, number 2
• A replacement uplink module or cover panel
• An antistatic bag or antistatic mat
The uplink module in EX4300 switches is hot-removable and hot-insertable field-replaceable unit (FRU):
You can remove and replace it without powering off the switch or disrupting switch functions.
CAUTION: We recommend that you install either a replacement uplink module or a
cover panel in the empty module slot to prevent chassis overheating and dust
accumulation.
To remove an uplink module from the switch (see
Figure 94 on page 306):
1. Take the uplink module offline by issuing the following CLI command:
user@switch> request
chassis pic offline fpc-slot slot-number pic-slot slot-number
2. Wrap and fasten one end of an ESD wrist strap around your bare wrist, and connect the other end of
the strap to the ESD point on the switch.
3. Loosen both captive screws on the faceplate of the uplink module by using your fingers. If you are
unable to unscrew the captive screws by using your fingers, use the screwdriver.
CAUTION: Do not pull the uplink module out of the module slot by holding the
faceplate of the uplink module.
