EC-1s, to “A” or “B” side of chassis. Accommodates up to 84 DS-1s and three DS-3/EC-1s per chassis side.
•
Backplane filler (BP-COVER-A and BP-COVER-B) – blank backplane filler for use when EIA is not installed.
Q.
What is the minimum hardware configuration required for the ONS 15310-MA?
A.
The minimum equipment required for the Cisco ONS 15310-MA consists of a chassis, fan tray, filter, one CTX card with SFP optics, one
CTX filler card, four expansion-slot filler cards, and two backplane covers, if EIA cards are not installed.
Q.
What are the power requirements of the Cisco ONS 15310-MA?
A.
The Cisco ONS 15310-MA installation requires the use of ground cable, #6 AWG stranded copper conductors for grounding, and
#14 AWG stranded copper conductors for power. Use of a 15-ampere (A) fuse is recommended. The system operates between –40.5 volts (V)
and –56.7V DC. A typical configuration would draw about 300 watts (approximately 6.5A DC at –48V).
Q.
Does the Cisco ONS 15310-MA support redundant power supply?
A.
Yes, the Cisco ONS 15310-MA has the following power characteristics:
•
Redundant terminal blocks are used for connecting power, and inputs are on the back of the sub-rack with “A” and “B” at opposing corners.
•
Battery A and B are independent.
•
Return A and B are independent.
•
A feed and B feed are independently monitored.
