CAUTION
The procedures in this chapter are for qualified service personnel.
CAUTION
Do not unscrew and remove the top cover of the Brocade ICX 7450. There are no user-serviceable parts inside the Brocade
ICX 7450.

Temperature threshold levels

The fan speed settings are set by the Brocade ICX 7450, and are not configurable.

Hardware maintenance schedule

Brocade ICX 7450 switch hardware components require minimal maintenance. Brocade recommends cleaning the fiber-optic
connectors on a fiber-optic port and the connected fiber cable each time you disconnect the cable.

Replacing a fiber-optic transceiver

You can remove an SFP, SFP+, or QSFP+ transceiver from a slot and replace it with a new one while the Brocade ICX 7450 is powered
on and running.
This section provides information about the following tasks:
•
Removing a copper or fiber-optic transceiver
•
Cabling a fiber-optic transceiver
•
Cleaning the fiber-optic connectors

Removing a fiber-optic transceiver

While removing a fiber-optic transceiver, be sure to wear an ESD wrist strap that is connected to ground.
CAUTION
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
