Equipment Options
The 3420S includes options for power, fiber optic cables types, redundancy, and management.
Power supply options include AC or DC and single or dual (redundant) power supplies with
connectors on the rear panel; see Figure 2. To reduce the load on each supply and extend their life,
both supplies provide power at the same time. If a supply fails, the power supply monitor card turns
off the corresponding Power LED, and, optionally, sends an alarm to the network management
module.
Fiber optic options includes single or dual (redundant) fiber optic transmitters and receivers. If the
primary transmitter or receiver fails, the 3240S turns on the alarm LED and, optionally, sends an
alarm to the network management module. An optional HI/LO power switch for each transmitter
(except low-power transmitters) provides compensation for link losses of typically more or less than 6
dB. Use the 3240S with 50/125 and 62.5/125 micron multimode fiber optic cable or single mode
8-10/125 micron fibers, depending on the transmitter option. The transmitter options include:
• 850 nm transmitter for multimode fiber only
• Low-power 1300 nm transmitter for multimode or single mode fiber
• High-power 1300 nm transmitter for multimode or single mode fiber
• Long-distance 1550 nm transmitter for single mode fiber only
The SNMP Management module can be installed either at the factory or in the field (for details, see
page 2-4). See Figure 1. The module provides two ports.
• 9-Pin RS-232 Serial Port Supports RS-232 protocols
• 10BASE-T Port Supports standard 10 Mbps Ethernet
