Hardware maintenance schedule
The device requires minimal maintenance for its hardware components. Brocade recommends
cleaning the fiber-optic connectors on a fiber-optic port and the connected fiber cable each time
you disconnect the cable.
Otherwise, you can replace the following hardware components as needed:
• Copper and fiber optic modules (SFPs (mini-GBICs))
Replacing a fiber optic module
You can remove an SFP from a slot and replace it with a new one while the FWS624 is powered on
and running.
This section provides information about the following tasks:
• Removing a fiber optic module
• Installing a new fiber optic module
• Cabling a fiber optic module
Removing a fiber optic module
You can remove a fiber SFP (also called a mini-GBIC) from a slot while the device is powered on and
running.
Before removing a fiber optic module, have the following on hand:
• An ESD wrist strap with a plug for connection to the ESD connector on the device.
For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.
