Removing A Spim - Cabletron Systems MRX Installation Manual

ADDING/REPLACING SPIMs

5.2 REMOVING A SPIM

The steps in this section describe removing an existing SPIM. You
should use this procedure only if you are replacing an existing SPIM,
either to change from one media type to another or to replace a SPIM
that has failed. If you are adding a new SPIM where none existed
before, then you can bypass this section and go on to Installing a
SPIM. The procedure is the same for both SPIM positions. Refer to
Figure 5-2 and remove the existing SPIM as follows:
1. Disconnect the SPIM interface cable from the HUB mother board
by opening the two latch ears on the cable connector.
2. Using the special offset 1/4-inch wrench supplied with the new
SPIM, remove the two 1/4-inch hex nuts and two washers that
secure the SPIM to the studs inside the HUB rear panel. Retain
the nuts and washers for later installation.
