Description

This front-to-back airflow plenum is an accessory for the Cisco NCS 540 N540-6Z18G-SYS-A and SYS-D fixed-port cell-site and aggregation router. It redirects the chassis' native front-to-side airflow to front-to-back, which suits racks and cabinets that need air to travel through the equipment from front to rear. It is typically used in 5G transport, mobile backhaul and small-footprint access and aggregation deployments.

The -23 variant is the version for 23-inch rack mounting. Its sibling, N540-6Z18G-PL-E, is the ETSI version. The host chassis is a 1 RU unit with 18x 1GE SFP and 6x 10/1GE SFP+ ports, up to 125 Mpps forwarding performance, a 4-core 2GHz CPU, 8 GB DRAM and 16 GB eMMC, running Cisco IOS XR. The DC chassis variant takes a wide-range DC feed of -20V to -72V. The system operating temperature is limited to 50 C when the plenum is fitted.

The plenum is a passive part that draws no power and needs no licence. It applies only to the N540-6Z18G-SYS-A/D router and is not applicable to other NCS 540 models. The plenum part number is 800-110707-01 and it is fixed with six screws.
