Chapter 6. SNMP Option

November 2001
6.1 Installation
Installation of the SNMP optional feature should be performed by
qualified service personnel only. As with all electronic devices that are
powered from an AC line, dangerous voltages may be present inside the
unit. The technician should exercise proper care and judgement. Only open
the unit for service after disconnecting the unit from the power source.
This documentation will explain in detail the proper procedure for
installation of the SNMP printed circuit board feature for the
ETU01-A. This procedure may also require replacement of the
operational firmware for older versions of the ETU01-A as the older
firmware does not support the SNMP card functions.
6.1.1 Required tools and supplies
1. No.2 Philips head screwdriver
2. thread lock compound (such as Glyptol™)
3. small, flat blade screwdriver (to aid in replacing firmware IC)
6.1.2 Procedure (Please refer to the attached drawing)
1. Inspect the contents of the SNMP kit. It should contain one(1) SNMP
card, three(3) brass standoffs, six(6) 3mm screws, MIB file floppy
diskette or CDROM, and possibly a 32pin EEPROM.
2. From the rear of the unit, disconnect all power, data port, and E1
cabling from the unit. Loosen the two captive thumb-screws located on
the lower left and right of the unit. Carefully slide the mother PCB out
of the case and place on a flat, clean work area. (Refer to Figure 6-1:
Firmware Chip Location.)
