Chapter 7. Maintaining the hardware

This chapter provides instructions for maintaining the hardware. See the "Safety

notices" on page xiii before starting any of these procedures.

CAUTION:

Servicing of this product or unit is to be performed by trained service

personnel only. (C032)

The chassis requires minimal maintenance for its hardware components. IBM

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:

v Management and interface modules

v Switch fabric modules

v POE daughter card

v Copper and fiber optic modules (SFPs and XFP transceivers)

v Power supplies

v Fan tray

v Blowers

To avoid problems with the connection between the fiber optic module (SFP or

XFP) and the fiber cable connectors, IBM strongly recommends cleaning both

connectors each time you disconnect and reconnect them. In particular, dust can

accumulate in the connectors and cause problems such as reducing the optic

launch power.

To clean the fiber cable connectors, IBM recommends using the fiber-optic reel-type

cleaner that shipped with your chassis.

When not using an SFP or XFP connector, make sure to keep the protective

covering on it.
