Upgrade Information

While SEQ-1G and SCS-1G plug-in accessories will address all bandwidths up to 1 GHz, you may
wish to reuse your current equalizers and cable simulators until you expand your system to
1 GHz.The following plug-in accessory information applies to all FlexNet 700, 800, and 900 series
upgrades. Please note:
SPB series PADs cannot be used. NPB series PADS are required.
MEQ return equalizers can be used.
All SEQ-750 and SEQ-862 series equalizers (with and without covers) can be used.
While the Flex Max901e trunk amplifiers are designed for 1 GHz operation, they can be
configured for use as spares in existing 750 or 870 MHz systems. Refer to Power Supply
Configuration beginning on page 5-3 for the appropriate plug-in accessories and locations
for 1 GHz or 750/870 operation.
Equalizers are keyed so they can only be installed one way. The Flex Max901es may have factory
installed jumpers that provide a continuous signal path across accessory plug-in areas. The two
types of jumpers include:
soldered-in jumpers
removable jumper wires
Before installing any accessories, these jumpers/jumper wires must be removed. Soldered-in
jumpers must be cut from the motherboard (see Soldered-in Jumper Removal on page D-5 for
instructions), while removable jumper wires can be pulled out. When the jumpers/jumpers wires are
removed, use an NPB-000, SEQ-0, or SEQ-1G-00 where appropriate to provide continuity (zero
loss) for the signal path.
