Thes e limits ar e design ed to prov ide re asona ble prote cti on agai nst harmf ul interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the inst ruction ma nua l, may ca use harmf ul interfer ence to ra dio com muni cations. Oper atio n of this e quipme nt in a residential area is likely to cause harmful interfe rence , in whi ch case users will be require d to corr ect the int erfer ence a t their own expen se.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and televisi o n r e ce p t ion. Thi s equipmen t has bee n teste d and fo und to co mply with the limits f or a Cla ss B di gital device in acco rdan ce with th e spec ific atio ns in part 15 of the FCC rules. These specifications are designed to provi de reason able pr otec tion agains t su ch interf erenc e in a resid ential installati on. Ho we ver, the re i s no gu a rantee that interference will not occur in a particular installation.

Modifying the equipment wit hout C isco’s w ritten authoriza tion may r esult in the e quipme nt no longer c omplyi ng with F CC requ irements for Class A or Class B digital devices.

Online Insertion and Removal

The Cisco AS5800 universal access server supports online insertion and removal (OIR). This feature

allows you to remove and replace a trunk card or port-handling card, while the system is operating,

without aff ect in g sy s tem op er at io n .

Caution In order to maintain traffic flow in a single dial shelf controller (DSC) configuration, the DSC

shouldn’t be removed while the system i s operational. If the DSC is removed, the interconnect

link between the DSC and router shelf will be lost and all other dial shelf cards will go down.

The router console port will display the following message:

AUG 2 10:57:02.017 CST: %DSC_REDUNDANCY-3-BICLINK: Link to active DSC down

CHAPTER

Each dial shelf card contains a female connector that connects to a male connector on the system

backplane. Each mal e backplan e connector comprises a s et of tiered pins in two lengths. The backplane

pins send s pe cifi c si gn al s to t he s y stem as th ey ma ke co nt act w it h th e ca rd c on n ect ors . Th e s y ste m

removed ones.

Each dial shelf card is designed with two ejector levers to be used when you install or remove a card.

The func tio n o f th e e jector levers is t o align and securely seat the ca rd co n ne cto r s in t he b ack p lan e.

Caution Do not fo r ce t h e d ia l sh el f car d s in to a slo t, as t hi s ca n damage the backp lan e co nn ec to r

pins if they are not aligned properly with the card connectors.

Busyout Command

To remove a CT1/CE1 trunk card without dropping calls or c onnections , you must first take the card out

of service by using the bus yout command to re mov e DS 0s and m odem re sou rces fro m the a v ail abl e pool

as calls ar e co m pleted. The busyou t command is run on a per card (slot) basis.

touchi ng the circui tr y o r any co nn e c tor pi ns.

Step 3 Slide the card into the slot until the ejector levers make contact with the chassis frame. (See Figure 1-2.) Step 4 Seat the card in the backplane by pushing the card firmly until the ejector levers fold in toward the card’s

front panel and the front panel is flush with the chassis frame.

Caution Always use the ejector levers to disengage or seat trunk cards, modem cards, VoIP cards,

or dial shelf controller cards in the backplane. Failure to do so can cause erroneous system error messages indicating a card failure. However, do not use the ejector levers to lift or support th e w eight of the c ar ds .

Chapter1 Replacing or Installing Dial Shelf Cards

Step 5 Tighten the pa ne l fa ste ne rs using a N o. 2 P hi ll ip s scr ewd r iver. This secur es the back p lan e co nn ec tio n

and ensures proper EMI shielding.

Caution Always tighten the panel fasteners. These fasteners prevent accidental removal and provide

proper grounding for the system.

Step 6 Repeat Step 2 through Step 5 for any other CT1/CE1 trunk cards that you want to install. Step 7 Install a bl an k fi ll er card ( D S 58- BLANK= ) in al l e m pt y card slots to ke ep th e ch ass is du s t-f re e a nd

maintain proper airflow.

Caution To prevent the overhea ti ng of inte rn al co mp o nents, alway s i nst all blank filler c a rds in

empty slots to maintain the proper flow of cooling air across the cards.

This completes the CT1/CE1 trunk card replacement procedure.

Instead of using the default algorithm for clock selection, you can specify clocks through global configuration and select a maximum of two clocks per trunk card.

If you configure fewer than two clocks on a trunk card and all other configured clocks fail, clock selection resorts to the default algorithm on that card and the second clock will be selected automatically.
