5.2.5 FKM-Blank

The FKM-Blank is a blank face plate that must be installed in any empty FKM

slot. When the RFL 3000 4K24 chassis contains less than two front-mounted FKMs, the
empty front slots must be covered with the FKM-Blank face plate in order to maintain
proper cooling air flow, and for safety, etc

Note:

The FKM-Blank

must be installed in

each empty PM slot.

6.0 TROUBLESHOOTING

All RFL 3000 Ethernet products are designed to provide reliability and

consistently high performance in all network environments. The installation of RFL
3000 4K24 Series Switches is a straightforward procedure (see INSTALLATION,
Section 2.6); the operation is also straightforward and is discussed in Section 4.

Should problems develop during installation or operation, this section is intended

to help locate, identify and correct these types of problems. Please follow the suggestions
listed below prior to contacting your supplier. However, if you are unsure of the
procedures described in this section or if the RFL 3000 4K24 Series Switch is not
performing as expected, do not attempt to repair the unit; instead contact your supplier
for assistance or contact RFL Customer Support.

6.1

Before Calling for Assistance

1.

If difficulty is encountered when installing or operating the unit, refer back to the
Installation Section of the applicable chapter of this manual. Also check to make
sure that the various components of the network are interoperable.

2.

Check the cables and connectors to ensure that they have been properly connected
and the cables/wires have not been crimped or in some way impaired during
installation. (About 90% of network downtime can be attributed to wiring and
connector problems.)

3.

Make sure that an AC power cord is properly attached to each RFL 3000 4K24
unit. Be certain that each AC power cord is plugged into a functioning electrical
outlet. Use the PWR LEDs to verify each unit is receiving power.

4.

If the problem is isolated to a network device other than the RFL 3000 4K24
product, it is recommended that the problem device is replaced with a known
