The following tables explains the function of the LEDs.
The PCC1 and PCC2 LEDs, which correspond to the top and bottom PC card slot respectively, vary in
meaning depending on what kind of card is currently installed.
Note: Although a red LED during boot mode usually signals an error, red LED patterns are
part of the normal operation of the MSS and are not necessarily indicative of errors or
dangerous operation.
Installing in a Wired Network
The MSS should be positioned close to the device it will be servicing. Since powering down the unit will
terminate any active sessions, it may be desirable to place the server in a location secure from user access.
Also be aware of the unit’s environmental operating limits and cabling requirements. See
Appendix C and
Appendix E for details.
