Useful info about Alarm Contacts in PXES6P :
1. Two-position terminal block (1,2) provided next to the DC power input, as shown above.
2. The Alarm Relay contact connected to the two terminals (1,2) is hardware operated.
3. By default it is NC (normally closed). It will open if there is any loss of power to the
electronics inside of the unit.
5.0 TROUBLESHOOTING
All Ethernet products are designed to provide reliability and consistently high
performance in all network environments. The installation of PXES6P Series 10/100 Mb/s
Switches is a straightforward procedure (see INSTALLATION, Section 3.0); 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
48
below prior to contacting your supplier. However, if you are unsure of the procedures described
in this section or if the PXES6P Series 10/100 Mb/s Switch is not performing as expected, do not
attempt to repair the unit; instead contact your supplier for assistance or contact EATON
Customer Support.
5.1
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.
If the fiber port does not link up while connecting to other device, do a quick
Loop test to test the fiber transceiver is functional or not. Use a short patch cable
of fiber and connect one end of cable to transmit and other end of receive to the
fiber port transceiver. If the Link LED turns solid green, then the fiber port is
functional and working.
4.
Make sure that an AC power cord is properly attached to each PXES6P Series
unit. Be certain that the AC power cord is plugged into a functioning and
appropriate electrical outlet. Use the PWR LEDs to verify each unit is receiving
power.
5.
If the problem is isolated to a network device other than the PXES6P Series
10/100 Mb/s switch product, it is recommended that the problem device is
replaced with a known good device. Verify whether or not the problem is
corrected. If not, go to Step 6 below. If the problem is corrected, the
PXES6P Series Switch and its associated cables are functioning properly.
6. If the problem continues after completing Step 5 above, contact your supplier
