CAUTION
Electronic modules can be damaged by ESD. When handling modules, wear an antistatic discharge wrist strap to prevent damage to electronic components. Place modules in antistatic packing material when transporting or storing. When working on modules, always place them on an approved antistatic mat that is electrically grounded.
Instructions for Installing the Module
The SHDSL T1/E1 LTU inserts into any access module slot (1 through 28) of a Total Access 3000 chassis. To install the SHDSL T1/E1 LTU, perform the following steps:
1.If present, remove the Access Module Blank (P/N 1181953L1) from the appropriate access module slot of the Total Access 3000 chassis.
2.Hold the unit by the front panel while supporting the bottom side with the ejector latch at the bottom, and the latch opened to engage the chassis edge when it is plugged in.
3.Align the module edges to fit in the lower and upper guide grooves for the designated slot.
4.Slide the module into the access module slot while pressing equally on the top and bottom of the front panel until the module is firmly positioned against the backplane of the chassis.
5.Lock the module in place by pushing in on the locking lever located on the lower
The SHDSL T1/E1 LTU initializes and goes opera- tional upon insertion into an active Total Access 3000 chassis. Initialization is indicated by the front panel LEDs.
LED Indicators
The front panel of the SHDSL T1/E1 LTU has five LED status indicators. Table 2 lists the LED descriptions.
