EX2500A Web Page Operation
•
Module Options
: this field allows the user to enable or disable specified EX2500A features.
o
RAM ECC
: if enabled, the EX2500A will perform memory error checking and
correction (ECC). This option may slow down performance, but increases reliability.
o
Check Backplane Clocks on Startup
: if enabled, the EX2500A will check the 10 MHz
and 16 MHz backplane clocks on startup. If these clocks are not within their
specifications, an error code will be generated on the network LEDs and the emergency
backup OS will start instead of the full system.
o
PPS Output
: if enabled, the EX2500A will generate a single pulse-per-second (PPS)
waveform on its the external trigger output.
•
Change Password
