AT-AR745 routers have a dedicated PAC slot. PAC slots can accommodate the
following PACs:
AT-AR060 EPAC, Encryption PAC.
AT-AR061 ECPAC, Compression/Encryption PAC.
PACs should only be installed by authorised service personnel. Unauthorised
opening of the router lid may cause danger of injury from electric shock, damage
to the router, and invalidation of the product warranty.
Front and Rear Panels
Front and rear panels of the AT-AR745 router with a PIC installed in each PIC
bay, and an AT-AR040 4-PIC NSM installed in the NSM bay, are shown in

LEDs and what they mean
Functions of the AR745's LEDs are shown in Table 22 on page 50. Additional
rear panel LEDs may be present if a PIC or NSM is installed. Functions of PIC
and NSM LEDs are described in their respective Hardware References.
