ES1008 Operating Manual Page 8
5.0 TROUBLESHOOTING
All Waters’ Ethernet products are designed to provide reliability and consistently high performance in all
network environments. The installation of Waters’ ES1008 switches is a straightforward procedure (see Section 3);
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 Waters’ ES1008 family of switches is not
performing as expected, do not attempt to repair the unit; instead contact your supplier for assistance or contact
Waters Network Systems’ Customer Service at 800-328-2275.
5.1 Before Calling for Assistance
1. If difficulty is encountered when installing or operating the unit, refer 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 Waters’ ES1008 switch. 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 Waters’ ES1008 switch, it is recommended that the
problem device be replaced with a known good device. Verify whether or not the problem is corrected. If not,
go to Step 5 below. If the problem is corrected, Waters’ ES1008 switch and its associated cables are
functioning properly.
5. If the problem continues after completing Step 4 above, contact Waters Network Systems Customer Service
at 800-328-2275 or email [e-mail] for assistance.
