2. BIOS Configuration  

Introduction 

The EPC-26A/27 uses the Phoenix BIOS. This section details the various 
menus and sub-menus that are used to configure the system. Your system 
may be pre-configured and require very little intervention. This section is 
written as though you are encountering each field in sequence and for the first 
time. 

 

Installation 

Before installing the EPC, unpack and inspect it for shipping damage. 

 

DO NOT REMOVE THE MODULE FROM ITS ANTI

-

STATIC BAG UNLESS 

YOU ARE IN A STATIC

-

FREE ENVIRONMENT

.

  THE EPC

,

 LIKE MOST 

OTHER ELECTRONIC DEVICES

,

 IS SUSCEPTIBLE TO ESD DAMAGE

.

  

ESD DAMAGE IS NOT ALWAYS IMMEDIATELY OBVIOUS

,

 IN THAT IT 

CAN CAUSE A PARTIAL BREAKDOWN IN SEMICONDUCTOR DEVICES 

THAT MIGHT NOT IMMEDIATELY RESULT IN A FAILURE

. 

 

ENSURE THAT THE INSTALLATION PROCESS AS DESCRIBED HEREIN 

IS ALSO PERFORMED IN A STATIC

-

FREE ENVIRONMENT

. 

Insertion in an EXM Carrier 

Insertion of the EPC into an EXM carrier is straightforward.  Remove a blank 
EXM panel from the carrier (by unscrewing the thumbscrews) and insert the  
EPC into the card guides.  Firmly press the EPC front panel to ensure that the 
module is properly seated in the subplane and secure it with the thumb-
screws.
