HDV Network Module LEDs
High-density network modules have an enable (EN) LED, and five LEDs for the PVDM banks,
numbered 0 through 4. The enable LED indicates that the module has passed its self-tests and is available
to the router. The BANK 0 through BANK 4 LEDs indicate the current operating condition of the
PVDMs installed on the card. (See
Figure 12 .) If the BANK LEDs do not come on after initial
installation and configuration, check that the PVDMs are properly seated in their slots.
