La sequenza di avvio del PRE prevede i seguenti passaggi distinti:
Caricare l'helper di avvio.
c10k-eboot-mz.120-16.6.ST1
Non supporta schede di linea; è possibile utilizzare solo l'interfaccia Fast Ethernet (FE) sul PRE.
Caricare l'immagine principale.
ubr10k-p6-mz.122-1.XF ubr10k-k8p6-mz.122-1.XF
Ognuno di questi tipi di schede di linea esegue un polling al PRE per il firmware:
Scheda di linea via cavo
TCC+
Tostapane
Gigabit Ethernet
POS (Optical Carrier 12)

La sequenza di avvio della scheda di linea RF prevede i seguenti passaggi:
ROM Monitor (ROMmon) carica l'helper di avvio nella scheda di linea.
L'assistente all'avvio invia il numero di versione del software e il tipo di scheda.
PRE scarica l'immagine corrispondente al tipo di scheda.
L'immagine software Cisco IOS viene decompressa ed eseguita.
L'interfaccia Barium è configurata in modo che i dati possano essere trasferiti al PRE.

L'helper di avvio continua a inviare il numero di versione del software e il tipo di scheda come keepalive. Se il microcodice viene aggiornato nell'ambiente PRE, il nuovo microcodice viene scaricato e l'aggiornamento viene eseguito automaticamente.
La sequenza di avvio di una scheda LAN o WAN prevede i seguenti passaggi:
La scheda di linea richiede la registrazione utilizzando il numero di versione del software e il tipo di scheda.
PRE scarica l'immagine corrispondente al tipo di scheda.
