Installing a GBIC in an MDA
Before installing a GBIC, see “GBIC MDA” on page 22 for
specific information about your MDA.
The 450-1GBIC MDA Host port is covered with a spring-loaded
filler panel that rotates out of the way as you push the GBIC into
place. You can install or replace a GBIC in an operating 450-
1GBIC MDA without turning off power to the switch.
For more information about GBICs, see the publication Installing
Gigabit Interface Converters (GBICs), part number 312865-A.
To install a GBIC in an MDA:
1 Remove the GBIC from its protective packaging.
2 Insert the GBIC into the MDA Host port ( Figure 11 ).
GBICs are keyed to prevent improper insertion. If the GBIC
resists pressure, do not force it. Remove it, turn it over, and
reinsert it.
Caution: Although GBICs are hot-swappable, MDAs
are not. To avoid damage to the switch or MDA, power
down the switch or unplug the switch module before
installing or removing an MDA.
