Installing the CSMIM-T1
CSMIM-T1 Hardware Installation Guide 2-5
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.)
2.4 INSTALLING THE CSMIM-T1
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.
Install the CSMIM-T1 into the MMAC-FNB (backplane) as follows:
!
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.
!
CAUTION
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
strap.
NOTE Although Cabletron Systems modules have “hot swap”
capabilities, we recommend that you power down the MMAC
hub prior to installation.
