Cabletron Systems manual Installing the CSMIM-T1

Installing the CSMIM-T1

Using Bypass Mode will allow a connection to the network to be maintained even though the system is powered down (or not on-line). If all channels are not being used for modem applications, the DSX1 interface could be used to drop-and-insert the PBX voice channels into the DS1 connection. (In this example, it requires that the PBX have an integral T1-CSU to terminate the network.)

CAUTION

In addition to J12 and J24, there are other jumpers on the module. These are used for diagnostic purposes, or are factory presets. Changing any of the jumper positions could cause damage to your module.

2.4INSTALLING THE CSMIM-T1

Installation should be performed by qualified personnel only.

CAUTION

The CSMIM-T1 is sensitive to static discharge. Follow static

!safety handling rules and properly wear an antistatic wrist

CAUTION strap.

When installing the CSMIM-T1, keep the following in mind:

•You may install the CSMIM-T1 in any slot except for slot 1 (farthest slot to the right) of the MMAC chassis.

•We suggest positioning the CSMIM-T1 next to any contiguous RIC MIMs or MIMs directly controlled by the hub managing device (e.g., EMME, EMM-E6, etc.). This does not apply to shunting MMAC-FNBs, where the data path remains unbroken, and allows non-interrupted communication.

NOTE

Although Cabletron Systems modules have “hot swap” capabilities, we recommend that you power down the MMAC hub prior to installation.

Install the CSMIM-T1 into the MMAC-FNB (backplane) as follows:
