Replacing the IOM in Slot 1
Enterasys I-Series Hardware Installation Guide 3-9
13. Insert the IOM into the sockets as follows:
a. Locate the sockets. The IOM must be inserted into these sockets.
b. Firmly push the IOM toward the front panel opening to compress the sealing gasket.
c. Carefully line up the two posts with the holes in the back of the IOM. Let the IOM rest on
the posts.
d. Gently push down on the IOM until the IOM plugs into the sockets. The IOM will be flush
against the posts.
14. Insert the two screws previously removed from the posts. Do not overtighten. The torque
should be 8 in-lbs.
15. Secure the IOM to the front of the switch.
a. If the replacement IOM had an attached cable retention bracket but you do not plan to use
it, use the two front panel screws previously removed to secure the IOM to the front of the
switch.
b. If you do plan to use the cable retention bracket, you will attach it to the chassis after the
port cables have been inserted, which at the same time will secure the IOM to the front of
the switch. Refer to “Securing the IOM Cables” on page 2-34 for more information.
16. Replace the bottom cover and reinsert the screws.
17. If necessary, replace the switch in the rack (described in Installing the Switch into a Rack on
page 2-11) or reinstall the DIN rail clip (described in Installing the Switch to a DIN Rail on
page 2-14).
18. Go to “Completing the Installation” on page 2-35 for the procedure to reapply power and
check the LEDs.
