Cisco ONS 15454 SDH Product Overview, R3.4

September 2002

Hardware

The European Telecommunications Standards Institute (ETSI) rack can hold up

to three ONS 15454 SDHs and two air ramps. Although the ETSI rack is not

typically supplied by Cisco, you can order shelf assemblies pre-installed in an

ETSI rack.

The shelf assembly weighs approximately 26 kilograms (57.3 pounds) without

cards installed. The rack has two front doors for added security, a fan-tray module

for cooling, and extensive fiber routing and management facilities.

LCD

The ONS 15454 SDH LCD screen provides slot- and port-level information for

all ONS 15454 SDH card slots, including the number of critical, major, and minor

alarms.

You can use the LCD screen to set the IP address, subnet mask, and default router for

the node. This allows you to accomplish these basic operations without a computer.

In CTC you can limit use of the LCD by other users by choosing to prevent LCD IP

conﬁguration. Users can still view information on the LCD, but cannot perform any

provisioning. The ONS 15454 SDH LCD is shown in Figure 26.

to alarm contacts, external interface contacts, and power terminals, LAN

connections, the BITS clock, and cable connectors.
