Removing An I/O Module - Extreme Networks PoS Installation And User Manual

Removing an I/O Module

To remove an I/O module, follow these steps:
1 Put on the ESD-preventive wrist strap that is provided with the chassis, and verify
that the metal end of the leash is connected to the ground receptacle located on the
top-left corner of the BlackDiamond 6800 series switch front panel.
2 Identify the I/O module to be replaced and write down the following information
for later use:
— The chassis slot number and the type of I/O module. When you install the
replacement I/O module, install it in the same chassis slot.
— The optical-fiber cable connections to the I/O module connectors. You must
reconnect the cables to the same connectors on the replacement I/O module.
3 Disconnect all of the optical-fiber cables from the I/O module and set them carefully
aside.
4 Use the #1 Phillips-head screwdriver to loosen the captive screw at each end of the
I/O module front panel.
5 Grasp both ejector/injector handles and pivot them simultaneously away from each
other to unseat the module from the chassis backplane.
6 Use the ejector/injector handles to pull the module part way out of the chassis slot.
Do not touch the printed circuit board or any connector pins.
7 Grasp the module front panel with one hand and place your other hand under the
metal card carrier to support the weight of the module. Slide the module completely
out of the chassis slot. Place the module immediately into an antistatic sack to
protect it from ESD damage and prevent dust from collecting on the module's
optical-fiber connectors.
8 Install and secure the replacement module as described in the "Inserting and
Securing a Module" on page 2-7.
9 Check your notes on the slot assignment and cable connection information that you
wrote down before removing the defective I/O module, then reconnect the network
interface cables to their assigned ports on the I/O module.

Be very careful in handling optical-fiber cables: kinks and sharp bends can
destroy or degrade the cable's ability to convey light pulses accurately.
There is an EMI-preventive gasket attached to one edge of the module front
panel. To prevent diminished EMI protection, handle the module carefully and
avoid damage to this gasket.
