LED1 (Green) lit, indicates that the SMDR-E ETU is receiving power.

2.Connection of SMDR

A.The SMDR-E ETU must be installed into either OPT1 or OPT2 slot (or a combination

slot) of any CCU. Prior to installing the SMDR-E ETU, ensure that switch SW1 is set to the ON position and that the baud rate switch, DIPl, is set to the proper position.

When installing the SMDR-E ETU, turn SW2 OFF for insertion of this ETU into the slot without powering down the CCU.

B.Route the RS-232C connector ended cable down and to the right side of the CCU in a

manner to avoid interference with the insertion and the removal of ETUs and with

the 25pair cables from Jl - 53 connectors. Remove the access panel on the right side of the CCU, which covers three openings, to

mount RS-232C connectors. (See Figure

200-26).

240.8LCR-EETU

The LCR-E ETU contains three switches, an LED and a RS-232C connector ended cable.

1.Switches:

Switch 1, designated SWL, is used to connect

backup battery to the LCR-E MEMORY. This switch should be set to the ON position to allow

memory retention during power failure or brownouts, for approximately seven days.

Switch 2, designated SW2 RESET, is a slide switch used to reset the LCR-E ETU, with interruption of all ongoing operation. This switch is also used to busy out the ETU when the ETU is
