Installing the 3240S
To install the 3420S, follow these steps:
1. Place the 3420S on a flat, secure surface as a standalone unit or use the brackets to mount it in a
standard 19-inch rack. Figure 7 shows how the brackets can be attached.

2. On the main board, set the W12/W13 jumper for the relay contacts for the external alarm. With
the power off, pull out any I/O card(s) for access to the main board, then place the jumper on
W12 for normally closed contacts or on W13 for normally open contacts.
3. To insert an I/O Card, slide the card into the guides and press it firmly at the center to seat the
connector in the backplane, then hand-tighten the thumbscrews. To remove an I/O card, loosen
the thumbscrews and grasp them to pull the card out.
Normally installed at the factory, you can install the SNMP module in the field; see Figure 1.
Caution: The SNMP module is not hot-swappable.
4. Remove the blank cover panel over the SNMP module slot.
5. Slide the SNMP module along the card guides and press it securely into the connector, then
tighten the captive screws.
Note: Dirty optical connectors are a common cause of link loss or attenuation problems, especially
for single mode fiber (SMF). Clean the connectors before plugging in a cable and whenever
there is a significant or unexplained light loss. To prevent contamination, always install
protective dust covers on unused fiber optic connectors.
6. Wipe the ferrule and the end-face surface of the male fiber coupler with a lint-free, isopropyl
alcohol pad from a fiber cleaning kit.
7. Use canned air to blow any dust out of the female fiber coupler.
