3.2.3 Installing the TRXMIM into an MMAC
Note:
The installer should be prepared to monitor the LANVIEW LEDs
as described in Section 3.2.4, Boot-up Check. Because the sequence may
proceed rapidly, please read Section 3.2.4 to prepare for this task before
installing the TRXMIM.
Note:
Although the TRXMIM may be “hot swapped” when servicing,
Cabletron Systems recommends powering-down the hub before installing
any module, whenever practical.
Install the TRXMIM into the MMAC as follows:
1. Remove the coverplate from the selected MMAC slot and slide
the TRXMIM into the MMAC chassis (see Figure 3-9). Be sure
that the card is in the card guides at the top and bottom of the
chassis.
2. Secure the module to the MMAC by tightening the knurled
knobs. Failure to firmly secure the MIM may result in improper
operation.
The TRXMIM is now installed.
