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.
